Lithosphere consists of
crust and uppermost solid mantle
Correct Answer: Option 3 (Crust and Uppermost Solid Mantle)
Explanation:
The lithosphere is the rigid, outermost rocky layer of the Earth. It is divided into tectonic plates and includes:
- The crust (both continental and oceanic crust)
- The uppermost solid part of the mantle
These two layers together form a single rigid unit known as the lithosphere.
The lithosphere floats on the asthenosphere, which is a hotter, softer, and more ductile layer of the upper mantle located beneath it.
Therefore, the lithosphere consists of the crust and the uppermost solid mantle.
