Question

9. In convection currents, hot air moves​

Answer 1

Answer:

In convection currents, hot air moves down

Answer 2

Answer:

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source.

Explanation:

simple example of convection currents is warm air rising toward the ceiling or attic of a house. Warm air is less dense than cool air, so it rises. Wind is an example of a convection current. Sunlight or reflected light radiates heat, setting up a temperature difference that causes the air to move.
