Answer 2

Hot material near Earth's core is less dense and rises, and when it cools, it becomes more dense and sinks.

This process, known as convection, plays a significant role in the movement of materials within Earth's interior. Convection occurs when heat is transferred from one place to another by the movement of fluids, such as molten rock or magma. As hot material near the core rises, it cools and becomes more dense, causing it to sink back down towards the core. This creates a circular flow of material within the Earth's interior, with hot material rising towards the surface and cool material sinking back down towards the core.

Convection is one of the mechanisms that drives the movement of materials within the Earth's interior, including the movement of tectonic plates at the Earth's surface. This process helps to distribute heat and maintain a relatively stable temperature within the Earth's interior over time.
