This is because there is much less pressure on this layer than the one below it (the outer core adds a lot of pressure to the inner core!). A. lithosphere. The crust is made up of rocks and minerals. Newton's laws of gravity as they relate to forces were quite right; but both Newton and Halley were wrong about the density of the Earth as compared to the moon. Earth's Atmosphere Layers & Composition | What is Atmosphere? Core. Starting just under the crust, the mantle stretches some 800 miles (1300 kilometers) inward. The only layer that can support life is the crust. What is the name of the outermost layer that is cool, solid, and includes all of the crust and a small part of the upper mantle; it is divided into pieces that move over the Earth's surface?
