E.) Mesosphere, Asthenosphere, Outer layer
Unfortunately there is no standard terminology for three mantle layers.
<span>I can be sure that "ionosphere" and "thermosphere" refer </span>
<span>only to atmospheric layers, so you can rule out A, B, and D. </span>
<span>"Mesosphere" may be used to refer to an atmospheric layer, </span>
<span>but is also often used to refer to a mantle layer. </span>
<span>
, </span>
<span>so I'll go with E even though I don't like it much. </span>
<span>I guess what is meant by "outer layer" is the part of the lithosphere </span>
<span>that does not match crustal composition.</span>
Answer:
it's called the lithosphere, it's the crust of the earth; the rocky outer layer of the earth.
