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

Explanation:

Convection is a process by which less dense material rises and more dense material sinks near Earth's surface. Water, air, rocks and other materials expands when temperature rises and they become less dense. When the water is heated it becomes vapors and carries away thermal energy from the water.
