Question

4. Why does warm air rise?
Cool gas molecules move less and take
a up more space so they become less
dense
b
C
The higher pressure on air at sea level
pushes it up higher in the atmosphere
The temperature gradient of warm air is
higher than that of cold air
Warm gas molecules move more and
d take up more space so they become less
dense

Answer 1

Final answer:

Warm air rises because of its lower density compared to cold air.

Explanation:

Warm air rises due to its lower density compared to cold air. As the air near the surface gets heated, it expands, becomes less dense, and rises. This creates an area of low air pressure at the surface, leading to the upward movement of warm air.
