Question

What is the difference between a layer based on composition vs. Response to stress?

Answer 1

Answer:

There are differences between layers of the earth based on composition and in response to stress.

Explanation:

There are three layers of Earth based on 'chemical composition': the crust, the mantle, and the core. The outermost part is the crust which is less than 1% of Earth by mass. It consists of oceanic crust and continental crust. The mantle is hot and the last layer core is mostly composed of iron metal.

The physical behavior of earth depends on how much pressure it faces and its repose to stress. As we go deep inside the earth, the pressure and temperature increase. Lithosphere, Asthenosphere, Upper and lower mesosphere, outer and inner core are layers of Earth subjected to pressure. Lithosphere is the strongest layer. Asthenosphere being weaker than lithosphere.
