Question

Cold air is less dense, so it rises. As the cold air rises, warm air descends.
B
Big weather events like hurricanes and tornadoes cause convection currents.
C
Wind causes convection currents by stirring up the air.
D
Warm air is less dense, so it rises. Cold air moves in to take its place.

The correct answer is: **D** Warm air is less dense, so it rises. Cold air moves in to take its place.
This explanation accurately describes the mechanism of convection currents in the air. When the warm air rises, it creates an area of lower pressure, and cooler, denser air moves in to fill that space, resulting in a convection current.
