Question

which are correct descriptions of layers of the earth based on phase state? select all that apply

check all that apply

the crust is the surface layer composed of rocks like granite.

the asthenosphere is below the earth and behaves like a liquid.

the mantle is the shallow, solid layer composed of granite rock.

the lithosphere is solid crust and upper mantle.

Explanation:

• The crust is the outermost layer of the Earth, composed of rocks like granite.
• The asthenosphere is a layer below the lithosphere and behaves like a viscous liquid (due to high temperatures and pressures allowing slow flow).
• The lithosphere is defined as the solid crust and the uppermost rigid part of the mantle.
• The mantle is not composed of granite (granite is a crustal rock). The mantle is made of silicate rocks in a solid - to - semi - solid state (depending on depth), not granite.

Answer:

• The crust is the surface layer composed of rocks like granite.
• The asthenosphere is below the earth and behaves like a liquid.
• The lithosphere is solid crust and upper mantle.
