Question: 1 / 400

What role does temperature play in the formation of wind?

Temperature does not affect wind

It only affects humidity

Temperature differences can create pressure differences

Temperature plays a crucial role in the formation of wind because it directly influences air pressure. When the sun heats the Earth's surface, areas with higher temperatures will warm the air above them. As warm air rises, it creates a region of lower pressure. Conversely, cooler areas lead to higher air pressure due to the denser, colder air.

This difference in temperature creates a pressure gradient, where air moves from high-pressure areas to low-pressure areas, generating wind. As a result, the movement of air is driven by the temperature variations across different regions, making temperature a fundamental factor in wind formation.

The other options relate to aspects of weather dynamics but do not capture the direct role temperature plays in creating wind through pressure differences.
