Question

immersive reader
wind is ______ rushing in to fill an area of low pressure.
choose one option
a cool air
b fog
c warm air
d snow

Explanation:

Wind is formed when air moves from an area of high pressure to an area of low pressure. Cool air is denser (higher pressure in this context compared to the low - pressure area) and will rush in to fill the low - pressure area. Fog is a cloud on the ground (a suspension of tiny water droplets) and not related to the pressure - based wind formation. Warm air is less dense (usually associated with rising air in some cases but not the direct "rushing in" to fill low pressure as described here). Snow is precipitation (solid water) and not involved in this pressure - driven wind mechanism.

Answer:

A. cool air
