What is the geothermal gradient and what causes it?

• The increase in temperature with depth beneath the Earth's surface, caused by heat release during Earth's formation
• The cooling of the Earth's core, caused by convection currents
• The melting of the Earth's crust, caused by volcanic eruptions
• The movement of tectonic plates, caused by earthquakes
