Explain how the composition of the mantle is important to plate tectonics

The composition of mantle plays a pivotal role for enhancing the energy and drifting forces for movement of plate tectonics.

Explanation:

The mantle of earth is formed of oxygen is high proportion, silicon and magnesium, along with presence of calcium, iron, aluminium, potassium and sodium. These are all combined in the form of silicates or oxides. Often, the molten rock material commonly known as magma that erupts from an volcano, accumulated in the earth crust on the mantle. The heat from the core of the earth is transmitted by the process of convection which is facilitated by mantle. This heat or energy is mainly responsible for movement of plate tectonics which results in disastrous consequences like earthquakes, volcanic eruptions and so on.
