Week 4: Life and Earth's Crust

Question 14 • SNHS NV-Environmental Science

Explain what differentiates the Earth’s crust and lithosphere.

Answer

Answer:

Earth’s crust is distinguished from the lithosphere because the crust refers to a compositional later and the lithosphere is a mechanical layer, the solid layer near the surface of the Earth. The crust is mostly composed of alumino-silicate minerals while the lithosphere includes some of the solid regions of the upper mantle which is mostly ferro-magnesium silicates.
