Question

Earth's uppermost mantle that overlaps with the crust; these are also the tectonic plates!

Answer 1

The Earth's uppermost mantle that overlaps with the crust is known as the lithosphere. It consists of both the crust and a portion of the upper mantle, ranging in thickness from about 10 to 100 kilometers. The lithosphere is broken into several large, rigid pieces called tectonic plates. These plates float on the semi-fluid asthenosphere beneath them and interact with each other at their boundaries, causing various geological phenomena such as earthquakes and volcanic activity. The movements and interactions of these tectonic plates are responsible for shaping the Earth's surface features and influencing the distribution of continents and oceans.
