WebTogether, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces. Layers of the earth. These plates are in constant motion. WebThe crust and the top layer of the mantle down to a depth of around 100 km (1.5%) are called the lithosphere. The lithosphere lithosphere is solid and rigid. A network of 14 major and a number of minor tectonic plates make up this layer. These solid plates carry both continents and oceans, and move on the top part of the mantle.

WebThe Earth's outer shell is divided into pieces called plates. Most volcanoes, mountains, and earthquakes occur where plates meet. Places where plates meet are called plate boundaries. There are seven major plates along with countless minor plates. You can see that a plate can be made of both oceanic crust and continental crust.
