The correct response is:
It cools down and descends.
The correct response is: It cools down and descends.
High-pressure systems occur when air cools down and becomes denser, causing it to sink. As air sinks, it compresses and creates an area of high pressure at the surface. This cooling and descending process often happens when air moves away from the equator towards the poles or when cool air from higher altitudes sinks down towards the surface.
