Question

What causes convection currents inside earth

Answer 1

Answer: Differential heating and pressure.

Convection currents occur when lighter (or not as dense) warm materials rise over cooler, more dense, and heavier material sinks below it. These movements occur inside the mantle, or the third from inner-most layer of the Earth, and are often the cause of tectonic plate moment.

Answer 2

Step-by-step explanation:

convection currents are the result of different heating, when warmer material (less dense) rises up while cool material (more dense) sinks. It created circulation patterns known as convection currents in the atmosphere, water, and the mantle of earth
