Assertion (A): 60°-65° latitudes in both the hemispheres have a low-pressure belt instead of high pressure. Reason (R): The low-pressure areas are permanent over oceans rather than on land.
- ABoth A and R are individually true and R is the correct explanation of A
- BBoth A and R are individually true but R is not a correct explanation of A
- CA is true but R is falseCorrect
- DA is false but R is true
Explanation
The correct option is C because Assertion A is true while Reason R is false.
Assertion A is true because the 60 to 65 degree latitude belts are known as the Subpolar Low Pressure Belts. These are formed due to the convergence of warm subtropical air and cold polar air, combined with the rotation of the earth which causes air to rise in these regions.
Reason R is false because the Subpolar Low Pressure belts are not permanent only over oceans. While pressure systems can be more intense over oceans due to less friction and more moisture, these low pressure belts are a global feature of the Earths atmospheric circulation and exist over both land and water. Furthermore, the reason for the low pressure at these latitudes is dynamic air movement rather than the underlying surface of ocean versus land.
