[1] Hailstorms are caused due to –
A.
condensation
B.
convection
C.
sublimation
D.
freezing
Ans:
freezing
Explanation :
In a hailstorm, small ice particles that form above the freezing level (which occurs in all thunderstorms) collect either rain water or cloud water on them, forming a water shell that freezes. The tilted updraft and downdraft structure of the storm is important in order for hailstones to grow because they can be `recycled' several times, until they either become too large for the updraft to carry them, or they get caught in a downdraft, and they finally reach the ground.

[25] Which is the warmest layer of the atmosphere?
A.
Thermosphere
B.
Troposphere
C.
Stratosphere
D.
Mesosphere
Ans:
Thermosphere
Explanation :
Troposphere, that extends up to a height of 12 km on an average from the surface of the earth, is the locale of all the vital atmospheric processes which create the climatic and weather conditions on the earth's surface. About half of the mass of air comprising the entire atmosphere is concentrated in this zone. This is the lowermost layer of the atmosphere.
Explanation :
Humidity is the amount of water vapor in the air. Humidity depends on water vaporization, and condensation, which, in turn, mainly depends on temperature. Temperature, in turn, is affected by weather and location.
[6] The temperature increases rapidly above –
A.
Ionosphere
B.
Exosphere
C.
Stratosphere
D.
Troposphere
Ans:
Exosphere
Explanation :
Above Troposphere, temperature increases rapidly with height in the Stratosphere layer as it houses the ozone layer which absorbs ultraviolet (UV) rays from the sun. Again, temperature increases rapidly with height in Thermosphere which comprises Ionosphere (lower part) and Exosphere (upper part). Temperature in Exosphere which is the uppermost layer of the atmosphere reaches up to more than 4500° Celsius.
[7] Marble is the metamorphosed form of –
A.
Shale
B.
Basalt
C.
Sandstone
D.
Limestone
Ans:
Limestone
Explanation :
Marble is a non-foliated metamorphic rock composed of re-crystallized carbonate minerals, most commonly calcite or dolomite. Geologists use the term "marble" to refer to metamorphosed limestone. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite rock. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. Primary sedimentary textures and structures of the original carbonate rock (protolith) have typically been modified or destroyed.
