WebMay 12, 2024 · Under the rigid layer of rock we live on, the Earth’s asthenosphere is like dense plastic. Because of its fluid-like properties, mantle convection can occur. Then, mantle convection is the main driver of plate tectonics. And it’s because of convection deep down beneath our feet that we have volcanoes and earthquakes as well.
WebMar 1, 2024 · The very slow motion of lithospheric plates “floating” on the asthenosphere is the cause of plate tectonics, a process associated with continental drift, earthquakes, the formation of mountains, and volcanoes.
