Describe the relationship between crust , mantle ,lithosphere , asthenosphere, and tectonic plates.

Crust is the the upper layer of the earth. There are two types of crust:

1)Ocean crust

2)Continental crust

Tectonic plate are generally made up of earth crust. The upper layer is mantle.The mantle is the mostly-solid bulk of Earth's interior. .

Crust and the upper layer combined to form lithosphere.They are about 80Km  deep.

The asthenosphere is ductile . They are deformed like silicon polymer in response to the warmth of the earth. The rocks actually flows, when stressed is appiled they are start moving deep interior of earth.
