If you know the answers to these questions, you’ll make 100 on your test.
1. Why does warm air rise and cold air sink?
 Because warm air is less dense than cold air
 Because warm air is denser than cold air
 Because warm air has less pressure than cold air
 Because cold air is less dense than warm air
2. When the atmosphere is warmed by the sun, a change in air pressure results in the
