Hello...

What creates the convection current inside Earth?

A. Rising and sinking of material

Answer 2

Answer: A. Rising and sinking of material.

Explanation:

Convection currents are caused by the cooling of material as it rises up, which leads to the same material to sink. This material then warms as it sinks to rise again. This is why we call them convection currents. Because they both rise, and sink, in a circular motion we call the convection current.
