25. What is the zone separating troposphere from the stratosphere is known as?
[A] Stratopause
[B] Mesopause
[C] Tropopause
[D] Thermopause
Show Answer
Correct Answer: C [Tropopause]
Notes:
The zone separating troposphere from the stratosphere is known as Tropopause. It has constant temperature and hence it is called tropopause. The temperature at the tropopause is about – 80 degree Celsius over the equator and about – 45 degree Celsius over the poles.
26. The Great Basin Desert is located in which among the following countries?
[A] Australia
[B] Saudi Arabia
[C] Russia
[D] United States
Show Answer
Correct Answer: D [United States]

27. What is the effect of rotation of earth on the direction of the winds called?
[A] Pressure Gradient Effect
[B] Coriolis Effect
[C] Frictional Effect
[D] Centripetal Effect
Show Answer
Correct Answer: B [Coriolis Effect]
Notes:
The effect of rotation of earth on direction of winds is called the Coriolis effect. It causes deflection in the direction of
winds. The winds blowing in the Northern Hemisphere are deflected to their right and those blowing in the Southern Hemisphere to their left under the Coriolis effect. This principle of deflection is called Ferrel’s Law.
28. Which kind of precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature?
[A] Convectional
[B] Cyclonic
[C] Orographic
[D] Frontal
Show Answer
Correct Answer: D [Frontal]
Notes:
Frontal precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature. Along the fronts, the warm air rises above the denser cold air. The mid-latitude regions experiencing the convergence of warm tropical and cold polar air masses are important areas receiving frontal precipitation.
29. Which among the following is/are effects of the salinity on ocean water?
- It affects the marine organisms and plant community.
- It is a potent factor in the origin of ocean currents.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:
The ocean salinity has significant effects on physical property of seawater and other aspects. Spatial variation in seawater salinity becomes potent factor in the origin of ocean currents. The ocean salinity also affects the marine organisms and plant community.
30. Which among the following statements is/are correct about Pelagic Deposits?
- Pelagic deposits include gravels, sands, muds, volcanic materials etc. which are derived through weathering and erosion of continental rocks by various denudational processes.
- They consist of remains of marine plants and animals in the form of different types of oozes.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: B [Only 2]
Notes:
Pelagic deposits consisting of remains of marine plants and animals in the form of different types of oozes cover about 75.5 per cent of the ocean areas.
Terrigenous deposits include gravels, sands, muds, volcanic materials etc. which are derived through weathering and erosion of continental rocks by various denudational processes.
