Which best describes what happens to air molecules when they absorb heat energy from the Sun?

Question

A.
The air molecules become less dense and rise as cooler, denser air sinks, creating wind.


B.
The air molecules become more dense and rise as cooler, denser air sinks, creating wind.


C.
The air molecules become less dense and rise as cooler, less dense air sinks, creating wind.


D.
The air molecules become more dense and rise as cooler, less dense air sinks, creating wind.

Answer 1

The best description of what happens to air molecules when they absorb heat energy from the Sun is:

A. The air molecules become less dense and rise as cooler, denser air sinks, creating wind.

When air molecules absorb heat, they gain energy and move faster, which makes the air less dense. This less dense, heated air rises, while cooler, denser air moves down to take its place, creating wind and air circulation.
