How does convection occur in the troposphere? The Sun’s rays heat Earth’s surface.
Warm air rises and cool air sinks.
The warm ground heats the air above it.
The Sun’s electromagnetic waves reflect off clouds.

the warm air rises and cool air sinks

Explanation:

The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. This is convection and is the main process by which the troposphere mixes and heats. Although convection stirs and mixes the troposphere, the higher it is the colder it becomes.
