Earth formation heat
WebThe remaining 20% is primordial heat of Earth formation and differentiation (Turcotte and Schubert, 1982). Most of this heat is lost through the Earth's surface: A small fraction is converted to other forms of energy that drive tectonism, magmatism and other internal dynamic processes . Three heat transfer mechanisms are thought to be effective ... WebDec 12, 2024 · The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions. Early textbooks showed mantle convection cells, like in a beaker of hot liquid on a Bunsen burner, pushing plates ...
