What cause convection currents in the atmosphere? A. Earth's spinning makes air masses move,

B. Warm surface air rises and then cools as it rises,

C. Warm and cold parts of the ocean circulate in patterns,

D. temperatures are different at the equator and at the poles.

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
