Answer:

Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.

Some of the causes are-

•heating and cooling of the fluid,
•changes in the fluid's density, and.
•force of gravity.

Convection currents in the atmosphere happen due to-

The heating of the Earth’s surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
