Answer:
the outside layer, mantle, inner core and core.
Explanation:
the outside rock layer is a hard outer crust that is relatively thin compared to the rest of the layers. When this layer cracks it can cause volcanic eruptions because the hot magma has built up a lot of pressure so it can force itself through the gap/crack. The mantle is the layers just under the crust. A lot of pressure is built up here as it has a thinner cooler layer above it and a hotter liquid/ hotter rocks just below it. The inner core. This is very hot as it can reach a temperature of around 6,000°c. this is a liquid layer just before the solid inner core of the earth. The core. This is the very centre of the earth and therefor the hottest. This solid centre has a rough minimum of 15,000°F and can roughly get as hot as the sun, scientists have proven that fact. I hope this helped a little with your issue :)
