What drives tectonic plates? Science Advances

WebPlate tectonics is a concept as basic to geology as evolution by natural selection is to biology or gravity is to understanding the orbits of planets. Looking at it from a different perspective, plate tectonics is a mechanism for Earth to transport heat efficiently from the interior, where it has accumulated, out to space. WebFor example, take the Great Rift Valley in Africa. The African, Arabian, and Indian plates are moving. The land of Africa east of the Great Rift Valley is separating from the rest of Africa. Eventually (a few million years), a new plate will be created, being the land that has separated. ( 6 votes) WebDec 12, 2024 · Heat and gravity are fundamental to the process.

The … WebThe movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth’s mantle below the crust. Earthquakes and volcanoes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years (Fig. 7.18).
