Question

What are tectonic plates?


Small pieces of Earth's crust that move.


Large pieces of Earth's asthenosphere that don't move.


Large pieces of Earth's lithosphere that move.

Answer 1

Tectonic plates are large pieces of Earth's lithosphere that move. The lithosphere is the outermost layer of the Earth, comprising the crust and the uppermost part of the mantle. These plates float on the semi-fluid asthenosphere beneath them and interact with each other at their boundaries, leading to various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
