Answer 1

The difference between the earth's crust and its mantle is primarily based on the difference in composition.

The difference between the lithosphere and the asthenosphere

The difference between the lithosphere and the asthenosphere on the other hand is primarily based on the difference in the state of the rocks/crust.

• The Lithosphere comprises the crust and upper-most solid mantle.

• The Asthenosphere, on the other hand, is composed of rocks in their molten state.

• While the lithosphere stretches from the top of the earth's crust down to the first 62 miles, the Asthenosphere lies beneath the lithosphere.
