Question:

What is the role of convection currents in plate tectonics?

Tectonic plates:

Tectonic plates are the fragmented pieces of the lithosphere, which is the topmost layer of the Earth. They sit on top of the asthenosphere.

Answer and Explanation:

Convection currents in the asthenosphere cause tectonic plates to move. The movement of the viscous asthenospheric rocks puts strain on tectonic plates and pulls them along.
