How does energy drive plate tectonics?

Question:

How does energy drive plate tectonics?

Tectonic plates:

Tectonic plates are the segments that make up the lithosphere, which is the outermost layer of our planet. They can move and interact with each other.

Answer and Explanation:

The tectonic plates move due to being pulled by convection currents. These occur in the asthenosphere - directly below. When a fluid is heated, it becomes less dense and moves upwards. It then cools and falls, where it can be heated again. These cycles and flows put strain on the tectonic plates and move them.
