The correct answer is convection.
The correct answer is convection. Convection is the process by which heat is transferred through the movement of a fluid. In the case of the Earth, the fluid involved is the semi-solid rock material in the mantle.
To understand how convection works, imagine a pot of boiling water on a stove. The heat from the burner heats up the water at the bottom of the pot, causing it to become less dense and rise to the top. As it rises, it transfers heat to the cooler water above it. The cooler water then becomes heated, rises, and the process continues in a circular motion. This is convection.
In the Earth's mantle, there are hot regions where the rock is less dense and rises towards the crust. As it rises, it transfers heat to the cooler rock above it and then sinks back down to the lower mantle. This continuous cycle of rising and sinking rock is responsible for transferring heat from the lower mantle towards the crust.
