Geophysical analysis reveals substantial variations in surface heat flow in continental crust, suggesting dynamic thermal dissipation from the planetary interior.
The terrestrial heat flow is defined as the quantity of heat escaping per unit time from the Earth’s interior across each unit area of the Earth’s solid surface. The quantity varies from place to place over the surface of the Earth, as well as with time throughout Earth history. The total heat being lost from the Earth
