Question

Statement (X): Rising air forms an area of high pressure.

Statement (Y): Sinking air forms an area of low pressure.

Options

• Both statements X and Y both are true

• Both statements X and Y both are false

• Statement X is true, and statement Y is false

• Statement X is false, and statement Y is true

Answer 1

Statement X is false, and statement Y is true

Explanation:

Rising air leads to an area of low pressure because, as warm air rises, it leaves less air near the surface, reducing pressure there. Conversely, sinking air forms an area of high pressure since the descending cooler air adds weight to the surface air layer, increasing pressure. This difference in pressure causes air to move from high to low pressure, creating winds. Thus, rising air is associated with low pressure and usually causes cloudy and wet weather, while sinking air is related to high pressure and generally brings clear and sunny conditions.
