Question

150 word essay on lithosphere​

Answer 1

Answer:

The planet Earth comprises several layers. Starting from the Earth’s surface, there are four main layers; namely, the crust, the mantle, the outer core and the inner core. The pressure and tempera­ture increases tremendously from the outer layers to the inner layers. Let’s take a look at each of them individually.

The lithosphere is underlain by the asthenosphere, the weaker, hotter, and deeper part of the upper mantle. The boundary between the lithosphere and the underlying asthenosphere is defined by a difference in response to stress the lithosphere remains rigid for very long periods of geologic time in which it deforms elastically and through brittle failure, while the asthenosphere deforms viscously and accommodates strain through plastic deformation.
