Answer 3

Why is the Earth's crust and upper part of the mantle called the lithosphere?

The Earth's crust and the upper part of the mantle are called the lithosphere due to their physical properties and behavior within the Earth's structure.

Physical Properties and Behavior: The lithosphere is the outermost shell of the Earth and is relatively rigid compared to the underlying asthenosphere. It includes the Earth's crust and the uppermost part of the mantle. The lithosphere behaves as a single, rigid layer on which the tectonic plates move.

Rigidity and Tectonic Plate Movement: The lithosphere is characterized by its rigidity, which allows it to be broken into tectonic plates. These plates are in constant motion, interacting with each other at their boundaries, leading to various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.

Conclusion: The term "lithosphere" is used to describe the Earth's crust and the upper part of the mantle due to their physical properties and behavior within the Earth's structure, including rigidity and tectonic plate movement.
