52. The circulation of ocean water occurs
- Option : C
- Explanation :
Ocean water circulates both laterally (horizontal movement such as ocean currents) and vertically (vertical movement such as upwelling and downwelling). These movements are driven by factors like wind, salinity, temperature differences, Earth's rotation, and gravitational pull.
-
Option A: only laterally
Incorrect. Lateral movement does occur, but vertical movement is also significant. -
Option B: only vertically
Incorrect. Vertical circulation is important, but lateral currents are a major part of oceanic movement. -
Option C: both laterally and vertically
Correct. Ocean circulation involves complex patterns in both directions. -
Option D: neither laterally nor vertically
Incorrect. Ocean water circulates actively in both dimensions.
-
- Option : C
- Explanation :
During winter, the Great Himalayas act as a barrier and prevent the cold polar winds from entering northern India. This natural wall blocks the icy winds from Central Asia, keeping much of India, especially the northern plains, warmer than other regions at the same latitude.
-
Option A: India is essentially a tropical country
Incorrect. This is true in general but does not explain the specific winter temperature difference. -
Option B: The surface wind blows in a particular direction in one season
Incorrect. Seasonal winds do affect climate, but this is not the main reason for warmer winters in northern India. -
Option C: The Great Himalayas check the penetration of cold polar air into India effectively
Correct. The Himalayas act as a climatic divide and shield the subcontinent from cold northern winds. -
Option D: Of winter rains
Incorrect. Winter rains are limited and do not significantly influence overall warmth.

- Option : C
- Explanation :
