How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
