Ans:
Equatorial region
Explanation :
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is almost daily occurrence and even distribution of rain, and temperate areas in summer. It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.

A.
Conduction
B.
Convection
C.
Radiation
D.
Tides
Ans:
Convection
Explanation :
During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.

Explanation :
In paleo-geography, Gondwana, originally Gondwanaland, was the southern most of two supercontinents that were part of the Pangaea supercontinent. It existed from approximately 510 to 180 million years ago. It included most of the landmasses in today's Southern Hemisphere, including Antarctica, South America, Africa, Madagascar and the Australian continent, as well as the Arabian Peninsula and the Indian subcontinent, which have now moved entirely into the Northern Hemisphere.
[17] The colour of loamy soil is –
A.
Greenish brown
B.
Bluish green
C.
Yellowish brown
D.
Blackish brown
Ans:
Blackish brown
Explanation :
Loam encompasses a variety of soil types, some granulated and nicely draining, while others may be thicker and have the consistency of mud. Most loam soils are a brown or black colour, making them ideal for gardens. It is often the most preferred type for plant growth and does well with just about any species. Large plants and trees, including maples and poplars, are both commonly found growing in loam soil. Loam is a Combination of small rock particles, organic matter and nutrients, often in ideal combinations for healthy plant growth. The granular soil retains water very easily, yet the drainage is well. Loamy soil is composed of 40 % sand, 40% silt and 20% clay.
[18] What is the interval between a high tide and neaptide at a given place?
A.
12 hours
B.
12 hours 26 minutes
C.
15 hours 30 minutes
D.
24 hours
Ans:
12 hours 26 minutes
Explanation :
Tide clocks are popular clocks used amongst surfers, sailors, and anyone else who is concerned with the tidal cycle. They run on a 12 hour and 25 or 26 minute cycle, which is the time it takes for the high tide to ebb and flow back to high tide again.
[19] Seismic sea waves which approach the coasts at greater force arc known as –
A.
Tides
B.
Tsunami
C.
Current
D.
Cyclone
Ans:
Tsunami
Explanation :
A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impadts and other disturbances above or below water all have the potential to generate a tsunami. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves.
[20] Which of the following is a cold ocean current?
A.
Humboldt current
B.
Brazil current
C.
Oyashio current
D.
Canary current
Ans:
Humboldt current

[23] Convectional Rainfall occurs in:
A.
Equatorial region
B.
Temperate region
C.
Tropical region
D.
Polar region
Ans:
Equatorial region
Explanation :
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is almost daily occurrence and even distribution of rain, and temperate areas in summer. It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.
[24] Land and sea-breezes occur due to :
A.
Conduction
B.
Convection
C.
Radiation
D.
Tides
Ans:
Convection
Explanation :
During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.
[25] Depression formed due to deflating action of winds are called –
A.
Playas
B.
Yardang
C.
Ventifacts
D.
Sand dunes
Ans:
Yardang
Explanation :
A yardang is a streamlined hill carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion, dust and sand, and deflation. Yardangs become elongated features typically three or more times longer than wide, and when viewed from above, resemble the hull of a boat.
Explanation :
Disaster planning is the creation of plans through which communities reduce vulnerability to hazards and cope with disasters. It does not avert or eliminate the threats; instead it focuses on creating plans to decrease the impact of disasters.
[6] Which of the following is a Bio-logical method of soil conservations?
A.
Contour fanning
B.
Contour terracing
C.
Gully control
D.
Basin listing
Ans:
Contour fanning
Explanation :
The biological methods of soil conservation include contour farming, strip cropping, tillage operation, mulching, etc. Contour farming is practiced in the hilly regions or on the slopes. The contours (circular or peripheral furrows) catch the downwardly moving water until it is absorbed in the soil. It reduces run off, saves more water for crops, and reduces soil erosion.
[7] With what bio-region is the term "Steppe" associated?
A.
Grasslands
B.
Tropical forests
C.
Savanna

[14] The layer where the decrease in temperature with increasing altitude is totally absent is –
A.
Troposphere
B.
Ionosphere
C.
Stratosphere
D.
Mesosphere
Ans:
Stratosphere
Explanation :
The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0°C. This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.

Blackish brown
Explanation :
Loam encompasses a variety of soil types, some granulated and nicely draining, while others may be thicker and have the consistency of mud. Most loam soils are a brown or black colour, making them ideal for gardens. It is often the most preferred type for plant growth and does well with just about any species. Large plants and trees, including maples and poplars, are both commonly found growing in loam soil. Loam is a Combination of small rock particles, organic matter and nutrients, often in ideal combinations for healthy plant growth. The granular soil retains water very easily, yet the drainage is well. Loamy soil is composed of 40 % sand, 40% silt and 20% clay.
[18] What is the interval between a high tide and neaptide at a given place?
A.
12 hours
B.
12 hours 26 minutes
C.
15 hours 30 minutes
D.
24 hours
Ans:
12 hours 26 minutes
Explanation :
Tide clocks are popular clocks used amongst surfers, sailors, and anyone else who is concerned with the tidal cycle. They run on a 12 hour and 25 or 26 minute cycle, which is the time it takes for the high tide to ebb and flow back to high tide again.
[19] Seismic sea waves which approach the coasts at greater force arc known as –
A.
Tides
B.
Tsunami
C.
Current
D.
Cyclone
Ans:
Tsunami
Explanation :
A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impadts and other disturbances above or below water all have the potential to generate a tsunami. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves.
[20] Which of the following is a cold ocean current?
A.
Humboldt current
B.
Brazil current
C.
Oyashio current
D.
Canary current
Ans:
Humboldt current
Explanation :
The Humboldt Current , also known as the Peru Current, is a cold, low-salinity ocean current that flows north-westward along the west coast of South America from the southern tip of Chile to northern Peru. It is an eastern boundary current flowing in the direction of the equator, and can extend 1,000 kilometers offshore. The Humboldt Current Large Marine Ecosystem (LME), named after the Prussian naturalist Alexander von Humboldt, is one of the major upwelling systems of the world, supporting an extraordinary abundance of marine life.

[23] Convectional Rainfall occurs in:
A.
Equatorial region
B.
Temperate region
C.
Tropical region
D.
Polar region
Ans:
Equatorial region
Explanation :
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is almost daily occurrence and even distribution of rain, and temperate areas in summer. It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.
[24] Land and sea-breezes occur due to :
A.
Conduction
B.
Convection
C.
Radiation
D.
Tides
Ans:
Convection
Explanation :
During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.
[25] Depression formed due to deflating action of winds are called –
A.
Playas
B.
Yardang
C.
Ventifacts
D.
Sand dunes
Ans:
Yardang
Explanation :
A yardang is a streamlined hill carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion, dust and sand, and deflation. Yardangs become elongated features typically three or more times longer than wide, and when viewed from above, resemble the hull of a boat.
Explanation :
Eratosthenes of Cyrene was a Greek mathematician, geographer, poet, athlete, astronomer, and music theorist. He was the first person to use the word -geography in Greek and he invented the discipline of geography as we understand it.
[12] The art and science of map making is called –
A.
Remote Sensing
B.
Cartography
C.
Photogrammetry
D.
Mapping
Ans:
Cartography
Explanation :
Cartography is the study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
[13] The deepest trench of the Indian Ocean is –
A.
Java trench
B.
Aleutian trench
C.
Atacama trench
D.
Diamantina Trench
Ans:
Diamantina Trench
Explanation :
The Sunda Trench, earlier known as the Java Trench, is the deepest point in the Indian Ocean. It is located in the northeastern Indian Ocean, with a length of 3,200 kilometres. The trench is considered to be part of the Pacific Ring of Fire as well as one of a ring of oceanic trenches around the northern edges of the Australian Plate.
[14] The layer where the decrease in temperature with increasing altitude is totally absent is –
A.
Troposphere
B.
Ionosphere
C.
Stratosphere
D.
Mesosphere
Ans:
Stratosphere
Explanation :
The stratosphere defines a layer in which temperatures rises with increasing altitude. At the top of the stratosphere the thin air may attain temperatures close to 0°C. This rise in temperature is caused by the absorption of ultraviolet (UV) radiation from the Sun by the ozone layer. Such a temperature profile creates very stable atmospheric conditions. Consequently, the stratosphere is almost completely free of clouds or other forms of weather.

A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impadts and other disturbances above or below water all have the potential to generate a tsunami. Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide, and for this reason they are often referred to as tidal waves.
[20] Which of the following is a cold ocean current?
A.
Humboldt current
B.
Brazil current
C.
Oyashio current
D.
Canary current
Ans:
Humboldt current
Explanation :
The Humboldt Current , also known as the Peru Current, is a cold, low-salinity ocean current that flows north-westward along the west coast of South America from the southern tip of Chile to northern Peru. It is an eastern boundary current flowing in the direction of the equator, and can extend 1,000 kilometers offshore. The Humboldt Current Large Marine Ecosystem (LME), named after the Prussian naturalist Alexander von Humboldt, is one of the major upwelling systems of the world, supporting an extraordinary abundance of marine life.
[21] In sea, plants are restricted up to the depth of –
A.
20 m
B.
200 m
C.
1000 m
D.
2000 m
Ans:
200 m
Explanation :
In sea, vegetations are found upto the depth of 200 m.
[22] El Nino occurs over –
A.
Atlantic Ocean
B.
Indian Ocean
C.
Pacific Ocean
D.
Mediterranean Sea
Ans:
Pacific Ocean
Explanation :
El Nino occurs over Pacific Ocean. El Nino is a southerly, warm ocean current.
[23] Convectional Rainfall occurs in:
A.
Equatorial region
B.
Temperate region
C.
Tropical region
D.
Polar region
Ans:
Equatorial region
Explanation :
Convection rain commonly occurs in warmed or heated areas such as equatorial/tropical regions, where there is almost daily occurrence and even distribution of rain, and temperate areas in summer. It is also common in the inter-tropical convergence zone (ITCZ). It happens when the ground surface is locally overheated and the adjacent air, heated by conduction, expands and rises.
[24] Land and sea-breezes occur due to :
A.
Conduction
B.
Convection
C.
Radiation
D.
Tides
Ans:
Convection
Explanation :
During the day, the sun warming the land also warms the air. Since land heats up quicker than water does, the air over land gets warmer than the air over the water. Consequently, the warmer air, being less dense moves up. To fill its place the cooler air over the water moves in to fill its place creating what is known as a Sea Breeze. Reversely, at night the land cools down faster than the water does, and creates a Land Breeze.
[25] Depression formed due to deflating action of winds are called –
A.
Playas
B.
Yardang
C.
Ventifacts
D.
Sand dunes
Ans:
Yardang
Explanation :
A yardang is a streamlined hill carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion, dust and sand, and deflation. Yardangs become elongated features typically three or more times longer than wide, and when viewed from above, resemble the hull of a boat.
