Mar 5, 2026 · This includes the movements of the Earth’s tectonic plates that result in the creation, destruction and rearrangement of the Earth’s crust and lithosphere.

Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit …

The map above shows names and generalized locations of Earth's major tectonic plates. These plates move and interact with one another to produce earthquakes, volcanoes, mountain ranges, ocean …
