WitrynaAlthough it is scorching under the Earth’s surface, the crust and mantle are mostly solid. This heat inside the Earth is caused by residual heat leftover from the original formation of Earth and radioactive decay. The rate at which temperature increases with depth is called the geothermal gradient.

Witryna12 wrz 2024 · Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements. WitrynaWhen this happens, the magma from the mantle rises up to make (or construct) a new crust. The movement of the plates over the mantle can cause earthquakes. Rising magma can also create shield ...
