Plate Tectonics Questions Medium
The driving force behind plate tectonics is the movement of the Earth's lithosphere, which is composed of several large and small plates. These plates are constantly moving due to the convective currents in the underlying asthenosphere. The main driving force behind plate tectonics is the heat generated from the Earth's core, which causes the asthenosphere to become less dense and rise towards the surface. As the asthenosphere rises, it pushes the overlying lithosphere, causing the plates to move. This movement is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
