Question

the innermost layer of the lithosphere​

Answer 1

Answer:

1. The lithosphere is the solid and the outer part of the Earth.

2. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure.

3. There is a layer below the lithosphere termed as asthenosphere is in between 80-200km.

4. The asthenosphere is a highly viscous, mechanically weak, and ductile, deforming region of the upper mantle.

5. The asthenosphere is the main source of magma and it is the layer over which the lithospheric plates/ continental plates move (plate tectonics).
