[1] Metamorphic rocks originate from—
A.
igneous rocks
B.
sedimentary rocks
C.
both igneous and sedimentary rocks
D.
None of these
Ans:
both igneous and sedimentary rocks
Explanation :
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build-up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are.
[2] The term 'epicentre' is associated with—
A.
earthquake
B.
folding
C.
faulting
D.
earth's interior
Ans:
earthquake
Explanation :
The epicenter is the point on the Earth's surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates. In the case of earthquakes, the epicenter is directly above the point where the fault begins to rupture, and in most cases, it is the area of greatest damage. However, in larger events, the length of the fault rupture is much longer, and damage can be spread across the rupture zone.
[3] Our atmosphere is divided into layers.
A.
Two
B.
Three
C.
Four
D.
Five
Ans:
Five
Explanation :
Earth has five primary layers, which are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. From the Earth upwards, those layers are: Troposphere: 0 to 12 km: Stratosphere: 12 to 50 km; Mesosphere: 50 to 80 km; Thermosphere: 80 to 700 km; Exosphere: 700 to 10,000 km.
[4] The forests which act as barriers against cyclones are :
A.
Alpine forests
B.
Mangrove forests
C.
Evergreen forests
D.
Monsoon forests
Ans:
Mangrove forests
Explanation :
Mangrove Forest acts as barriers against cyclones and other natural disasters like tidal waves and tropical storms. They act as live sea walls against disasters and help minimize damage done to property and life. They also slow soil erosion and stabilize tidal banks against rising sea level, another climate change hazard.
[5] Cyclones are caused due to –
A.
low pressure
B.
high pressure
C.
low temperature
D.
high density
Ans:
low pressure
Explanation :
Cyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure. In the northern hemisphere, cyclones are called hurricanes or typhoons and their winds blow in an anti-clockwise circle. In the southern hemisphere, these tropical storms arc known as cyclones, whose winds blow in a clockwise circle.
[6] What is a 'tornado'?
A.
A very high pressure centre
B.
A very low pressure centre
C.
A very high ocean wave
D.
A planetary wind
Ans:
A very low pressure centre
Explanation :
A tornado is a closed low pressure circulation which is marked by a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Low-pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.

less than the present
Explanation :
If there is no carbon dioxide in the earth's atmosphere, the temperature of earth's surface would be less than the present because carbon emission in the atmosphere is one of the major causes of global warming.
[8] Name the continent where 'Tundra' type of climate is not found –
A.
Europe
B.
Asia
C.
Africa
D.
North America
Ans:
Africa
Explanation :
The meaning of the word 'tundra' is 'a region in continents of Asia, Europe and North America, where the growth of trees is prevented due to low temperatures and permanently frozen subsoil'. These kinds of geographic areas are found near the North Pole and the South Pole. In physical-geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra.

The first known description of an anemometer was given by Leon Battista Alberti around 1450.
[10] Trade winds are due to –
A.
Conduction
B.
Convection
C.
Radiation
D.
Scattering
Ans:
Convection
Explanation :
The air moving across the surface towards the extra heated region is known as the trade winds. The region where the northern convective airflow meets the southern and the air starts heading up instead of across the surface is known as the doldrums by sailors. The upwelling warm moist air expands, cools and drops heavy rain, but since it's moving up instead of across it won't fill sails.
[11] The ocean which touches the Asian and American shores is-
A.
Atlantic
B.
Indian
C.
Antarctic
D.
Pacific
Ans:
Pacific
Explanation :
The Pacific Ocean extends from the Arctic in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, bounded by Asia and Australia in the west, and the Americas in the east. This largest division of the World Ocean and, in turn, the hydrosphere - covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined.
[12] El Nino is –
A.
a warm ocean current
B.
sea storm
C.
tropical disturbance
D.
another name of typhoon
Ans:
a warm ocean current
Explanation :
El Nino (Spanish name for the male child), initially referred to a weak, warm current appearing annually around Christmas time along the coast of Ecuador and Peru and lasting only a few weeks to a month or more. Every three to seven years, an El Nino event may last for many months, having significant economic and atmospheric consequences worldwide.
[13] Soil erosion on hill slopes can be checked by –
A.
Afforestation
B.
Terrace cultivation
C.
Strip cropping
D.
Contour ploughing
Ans:
Terrace cultivation
Explanation :
Terrace farming is a type of farming that was developed first by the Inca people. This method of farming uses "steps", called andenes that are built into the side of a mountain or hill. On each anden, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level. Additionally, these "steps" prevent a free flowing avalanche of water that would take plants with it and destroy the all of the crops on the hillside.
[14] The crop mainly grown in hills is :
A.
sweet corn
B.
sweet jowar
C.
sweet potato
D.
sweet pea
Ans:
sweet jowar
Explanation :
Sweet potato may be grown either on hills or beds. Rows need to be spaced 90-120 cm apart with plants spaced 30-40 cm apart in the row. It is known in Nepal as 'sakar kand.' It is grown both in the terai and the mid-hills throughout the country. It is the second most important root crop after potato in terms of production and area.
[15] Dumping of solid waste in lowlying areas earth cover is called as :
A.
Sanitary land filing
B.
Open dumping
C.
Composting
D.
Incineration
Ans:
Sanitary land filing
Explanation :
Sanitary landfills are low lying sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high.
[16] The cause of loss of forest cover is –
A.
Agriculture
B.
Building Industry
C.
Increasing population
D.
Toursim & pilgrimage
Ans:
Increasing population
Explanation :
Deforestation is a consequence of a quantum jump in population and the consequent over-exploitation of our natural ecosystems for space, energy and materials. Expanding agriculture due to a burgeoning population base is one of the most important causes of deforestation. As demands on agricultural products rise more and more land is brought under cultivation for which forests are cleared, grass-lands ploughed, uneven grounds leveled, marshes drained and even land under water is reclaimed.
[17] Coastal Andhra Pradesh and Orissa often face natural disasters due to –
A.
Cyclones
B.
Earthquakes
C.
Landslides
D.
Tornadoes
Ans:
Cyclones
Explanation :
During summer, the Bay of Bengal is subject to intense heating, giving rise to humid and unstable air masses that produce cyclones. Widespread death and property destruction are reported every year in exposed coastal states such as Andhra Pradesh and Odisha. Although cyclones affect the entire coast of India, the East Coast is more prone compared to the West Coast. Out of the cyclones that develop in the Bay of Bengal, over 58 percent approach and cross the east coast in October and November.
[18] A broad, low embankment built up along the banks of a river channel during floods is called –
A.
Delta
B.
Levee
C.
Flood Plain
D.
Dune
Ans:
Levee
Explanation :
A levee, dike, dyke or flood bank is a broad, low embankment built up along the banks of a river channel during floods. Levees are usually parallel to the way the river flows, so levees can help direct the flow of the river. Levees can also be artificially created or reinforced.
[19] Which of the following is an alternative theory to the Big Bang theory developed in 1948, stating that the universe does not change even though it is expanding over time?
A.
Oscillating Universe
B.
Steady State Universe
C.
Mirror Universe
D.
Eternal Inflation
Ans:
Steady State Universe
Explanation :
The Steady State theory (also known as the Infinite Universe theory or continuous creation) was developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter. It asserts that the observable universe is basically the same at any time as well as at any place.
[20] The constellation `Sapta Rishi' is known to Westerners as the –

Poles
D.
Equator
Ans:
Equator
Explanation :
An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 23 September. The equinoxes are the only times when the Sun is exactly overhead at a point on the equatorial line. On an equinox, day and night are of approximately equal duration all over the planet.
[25] Nappe is a kind of –
A.
fluvial feature
B.
folded structure
C.
erosional plain
D.
delta region
Ans:
folded structure
Explanation :
In geology, a nappe or thrust sheet is a large sheet like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding. They form when a mass of rock is forced (or "thrust") over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.
Explanation :
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build-up, and this causes them to change.

D.
Scattering
Ans:
Convection
Explanation :
The air moving across the surface towards the extra heated region is known as the trade winds. The region where the northern convective airflow meets the southern and the air starts heading up instead of across the surface is known as the doldrums by sailors. The upwelling warm moist air expands, cools and drops heavy rain, but since it's moving up instead of across it won't fill sails.
[11] The ocean which touches the Asian and American shores is-
A.
Atlantic
B.
Indian
C.
Antarctic
D.
Pacific
Ans:
Pacific
Explanation :
The Pacific Ocean extends from the Arctic in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, bounded by Asia and Australia in the west, and the Americas in the east. This largest division of the World Ocean and, in turn, the hydrosphere - covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined.
[12] El Nino is –
A.
a warm ocean current
B.
sea storm
C.
tropical disturbance
D.
another name of typhoon
Ans:
a warm ocean current
Explanation :
El Nino (Spanish name for the male child), initially referred to a weak, warm current appearing annually around Christmas time along the coast of Ecuador and Peru and lasting only a few weeks to a month or more. Every three to seven years, an El Nino event may last for many months, having significant economic and atmospheric consequences worldwide.
[13] Soil erosion on hill slopes can be checked by –
A.
Afforestation
B.
Terrace cultivation
C.
Strip cropping
D.
Contour ploughing
Ans:
Terrace cultivation
Explanation :
Terrace farming is a type of farming that was developed first by the Inca people. This method of farming uses "steps", called andenes that are built into the side of a mountain or hill. On each anden, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level. Additionally, these "steps" prevent a free flowing avalanche of water that would take plants with it and destroy the all of the crops on the hillside.
[14] The crop mainly grown in hills is :
A.
sweet corn
B.
sweet jowar
C.
sweet potato
D.
sweet pea
Ans:
sweet jowar
Explanation :
Sweet potato may be grown either on hills or beds. Rows need to be spaced 90-120 cm apart with plants spaced 30-40 cm apart in the row. It is known in Nepal as 'sakar kand.' It is grown both in the terai and the mid-hills throughout the country. It is the second most important root crop after potato in terms of production and area.

A.
Sanitary land filing
B.
Open dumping
C.
Composting
D.
Incineration
Ans:
Sanitary land filing
Explanation :
Sanitary landfills are low lying sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high.
[16] The cause of loss of forest cover is –
A.
Agriculture
B.
Building Industry
C.
Increasing population
D.
Toursim & pilgrimage
Ans:
Increasing population
Explanation :
Deforestation is a consequence of a quantum jump in population and the consequent over-exploitation of our natural ecosystems for space, energy and materials. Expanding agriculture due to a burgeoning population base is one of the most important causes of deforestation. As demands on agricultural products rise more and more land is brought under cultivation for which forests are cleared, grass-lands ploughed, uneven grounds leveled, marshes drained and even land under water is reclaimed.
[17] Coastal Andhra Pradesh and Orissa often face natural disasters due to –
A.
Cyclones
B.
Earthquakes
C.
Landslides
D.
Tornadoes
Ans:
Cyclones
Explanation :
During summer, the Bay of Bengal is subject to intense heating, giving rise to humid and unstable air masses that produce cyclones. Widespread death and property destruction are reported every year in exposed coastal states such as Andhra Pradesh and Odisha. Although cyclones affect the entire coast of India, the East Coast is more prone compared to the West Coast. Out of the cyclones that develop in the Bay of Bengal, over 58 percent approach and cross the east coast in October and November.

A.
Oscillating Universe
B.
Steady State Universe
C.
Mirror Universe
D.
Eternal Inflation
Ans:
Steady State Universe
Explanation :
The Steady State theory (also known as the Infinite Universe theory or continuous creation) was developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter. It asserts that the observable universe is basically the same at any time as well as at any place.

Poles
D.
Equator
Ans:
Equator
Explanation :
An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 23 September. The equinoxes are the only times when the Sun is exactly overhead at a point on the equatorial line. On an equinox, day and night are of approximately equal duration all over the planet.
[25] Nappe is a kind of –
A.
fluvial feature
B.
folded structure
C.
erosional plain
D.
delta region
Ans:
folded structure
Explanation :
In geology, a nappe or thrust sheet is a large sheet like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding. They form when a mass of rock is forced (or "thrust") over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.
Explanation :
Cyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure. In the northern hemisphere, cyclones are called hurricanes or typhoons and their winds blow in an anti-clockwise circle. In the southern hemisphere, these tropical storms arc known as cyclones, whose winds blow in a clockwise circle.
[6] What is a 'tornado'?
A.
A very high pressure centre
B.
A very low pressure centre
C.
A very high ocean wave
D.
A planetary wind
Ans:
A very low pressure centre
Explanation :
A tornado is a closed low pressure circulation which is marked by a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Low-pressure systems form under areas of wind divergence which occur in upper levels of the troposphere. The formation process of a low-pressure area is known as cyclogenesis.

the same
Ans:
less than the present
Explanation :
If there is no carbon dioxide in the earth's atmosphere, the temperature of earth's surface would be less than the present because carbon emission in the atmosphere is one of the major causes of global warming.
[8] Name the continent where 'Tundra' type of climate is not found –
A.
Europe
B.
Asia
C.
Africa
D.
North America
Ans:
Africa
Explanation :
The meaning of the word 'tundra' is 'a region in continents of Asia, Europe and North America, where the growth of trees is prevented due to low temperatures and permanently frozen subsoil'. These kinds of geographic areas are found near the North Pole and the South Pole. In physical-geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra.

Pacific
Explanation :
The Pacific Ocean extends from the Arctic in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, bounded by Asia and Australia in the west, and the Americas in the east. This largest division of the World Ocean and, in turn, the hydrosphere - covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined.
[12] El Nino is –
A.
a warm ocean current
B.
sea storm
C.
tropical disturbance
D.
another name of typhoon
Ans:
a warm ocean current
Explanation :
El Nino (Spanish name for the male child), initially referred to a weak, warm current appearing annually around Christmas time along the coast of Ecuador and Peru and lasting only a few weeks to a month or more. Every three to seven years, an El Nino event may last for many months, having significant economic and atmospheric consequences worldwide.
[13] Soil erosion on hill slopes can be checked by –
A.
Afforestation
B.
Terrace cultivation
C.
Strip cropping
D.
Contour ploughing
Ans:
Terrace cultivation
Explanation :
Terrace farming is a type of farming that was developed first by the Inca people. This method of farming uses "steps", called andenes that are built into the side of a mountain or hill. On each anden, various crops are planted, and when it rains, instead of washing away all of the nutrients in the soil, the nutrients are carried down to the next level. Additionally, these "steps" prevent a free flowing avalanche of water that would take plants with it and destroy the all of the crops on the hillside.
[14] The crop mainly grown in hills is :
A.
sweet corn
B.
sweet jowar
C.
sweet potato
D.
sweet pea
Ans:
sweet jowar
Explanation :
Sweet potato may be grown either on hills or beds. Rows need to be spaced 90-120 cm apart with plants spaced 30-40 cm apart in the row. It is known in Nepal as 'sakar kand.' It is grown both in the terai and the mid-hills throughout the country. It is the second most important root crop after potato in terms of production and area.
[15] Dumping of solid waste in lowlying areas earth cover is called as :
A.
Sanitary land filing
B.
Open dumping
C.
Composting
D.
Incineration
Ans:
Sanitary land filing
Explanation :
Sanitary landfills are low lying sites where waste is isolated from the environment until it is safe. It is considered when it has completely degraded biologically, chemically and physically. In high-income countries, the level of isolation achieved may be high.
[16] The cause of loss of forest cover is –
A.
Agriculture
B.
Building Industry
C.
Increasing population
D.
Toursim & pilgrimage
Ans:
Increasing population
Explanation :
Deforestation is a consequence of a quantum jump in population and the consequent over-exploitation of our natural ecosystems for space, energy and materials. Expanding agriculture due to a burgeoning population base is one of the most important causes of deforestation. As demands on agricultural products rise more and more land is brought under cultivation for which forests are cleared, grass-lands ploughed, uneven grounds leveled, marshes drained and even land under water is reclaimed.
[17] Coastal Andhra Pradesh and Orissa often face natural disasters due to –
A.
Cyclones
B.
Earthquakes
C.
Landslides
D.
Tornadoes
Ans:
Cyclones
Explanation :
During summer, the Bay of Bengal is subject to intense heating, giving rise to humid and unstable air masses that produce cyclones. Widespread death and property destruction are reported every year in exposed coastal states such as Andhra Pradesh and Odisha. Although cyclones affect the entire coast of India, the East Coast is more prone compared to the West Coast. Out of the cyclones that develop in the Bay of Bengal, over 58 percent approach and cross the east coast in October and November.
[18] A broad, low embankment built up along the banks of a river channel during floods is called –
A.
Delta
B.
Levee
C.
Flood Plain
D.
Dune
Ans:
Levee
Explanation :
A levee, dike, dyke or flood bank is a broad, low embankment built up along the banks of a river channel during floods. Levees are usually parallel to the way the river flows, so levees can help direct the flow of the river. Levees can also be artificially created or reinforced.
[19] Which of the following is an alternative theory to the Big Bang theory developed in 1948, stating that the universe does not change even though it is expanding over time?
A.
Oscillating Universe
B.
Steady State Universe
C.
Mirror Universe
D.
Eternal Inflation
Ans:
Steady State Universe
Explanation :
The Steady State theory (also known as the Infinite Universe theory or continuous creation) was developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter. It asserts that the observable universe is basically the same at any time as well as at any place.
[20] The constellation `Sapta Rishi' is known to Westerners as the –
A.
Seven Monks
B.
Alpha Centauri
C.
Big Dipper
D.

[22] Which one of the following is the largest planet?
A.
Jupiter
B.
Venus
C.
Saturn
D.
Uranus
Ans:
Jupiter
Explanation :
Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in the Solar System combined.
[23] The largest planet in our solar system is –
A.
Mars
B.
Jupiter
C.
Saturn
D.
Mercury
Ans:
Jupiter
Explanation :
Jupiter is the fifth planet from the Sun and is the largest planet in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains two and a half times the mass of all the other planets combined. It has a mass of 1.9 x kg and is 142,800 kilometers (88,736 miles) across the equator.
[24] Equinox occurs when the sun is vertically above .
A.
Tropic of Capricorn
B.
Tropic of Cancer
C.
Poles
D.
Equator
Ans:
Equator
Explanation :
An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 23 September. The equinoxes are the only times when the Sun is exactly overhead at a point on the equatorial line. On an equinox, day and night are of approximately equal duration all over the planet.
[25] Nappe is a kind of –
A.
fluvial feature
B.
folded structure

Ans:
folded structure
Explanation :
In geology, a nappe or thrust sheet is a large sheet like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding. They form when a mass of rock is forced (or "thrust") over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.

B.
Venus
C.
Saturn
D.
Uranus
Ans:
Jupiter
Explanation :
Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in the Solar System combined.
[23] The largest planet in our solar system is –
A.
Mars
B.
Jupiter
C.
Saturn
D.
Mercury
Ans:
Jupiter
Explanation :
Jupiter is the fifth planet from the Sun and is the largest planet in the solar system. If Jupiter were hollow, more than one thousand Earths could fit inside. It also contains two and a half times the mass of all the other planets combined. It has a mass of 1.9 x kg and is 142,800 kilometers (88,736 miles) across the equator.
[24] Equinox occurs when the sun is vertically above .
A.
Tropic of Capricorn
B.
Tropic of Cancer
C.
Poles
D.
Equator
Ans:
Equator
Explanation :
An equinox is an astronomical event in which the plane of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 23 September. The equinoxes are the only times when the Sun is exactly overhead at a point on the equatorial line. On an equinox, day and night are of approximately equal duration all over the planet.
[25] Nappe is a kind of –
A.
fluvial feature
B.
folded structure
C.
erosional plain
D.
delta region
Ans:
folded structure
Explanation :
In geology, a nappe or thrust sheet is a large sheet like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding. They form when a mass of rock is forced (or "thrust") over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.
Explanation :
The Steady State theory (also known as the Infinite Universe theory or continuous creation) was developed in 1948 by Fred Hoyle, Thomas Gold, Hermann Bondi and others as an alternative to the Big Bang theory. In the steady-state theory, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter. It asserts that the observable universe is basically the same at any time as well as at any place.
[20] The constellation `Sapta Rishi' is known to Westerners as the –
A.
Seven Monks
B.
Alpha Centauri
C.
Big Dipper

[21] Isohels are the isopleths of –
A.
sunshine
B.
flowering time
C.
rain
D.
clouds
Ans:
sunshine
Explanation :
An isohel is line drawn on a map connecting points that receive equal amounts of sunlight. It is derived from hellos, meaning 'Sun.'
