AI overview
Convection is the process where hot, less-dense material rises while cold, denser material sinks, creating a circulation pattern—as shown in Earth's mantle where hot rock moves upward and cold rock descends. This process matters because it is a fundamental way that heat moves through the Earth's interior and drives large-scale geological changes.

Convection is the transfer of heat through the physical movement of fluids (liquids or gases), where warmer, less-dense material rises and cooler, denser material sinks.
