The Cross section of the Earth is a visualization of the composition of the Earth in geological terms. One reason is that the Earth, when formed, was incredibly hot and it takes a very long time for this heat to be lost by convection currents. City Average January Movement of rock in Earth’s crust can occur because of heat flow, as hot rock rises and cool rock sinks, and because of new rock pushing older rock away from ridges. A. is located on glacial ice. The Earth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth and is the outermost layer.
