Question
The model shows the layers of Earth and heat transfer within the Earth's mantle. The method of heat transfer shown is -
Solution
The method of heat transfer shown within the Earth's mantle in such models is typically convection. Here's a step-by-step explanation:
- Heat from the core of the Earth heats the bottom layer of the mantle.
- As the mantle material is heated, it becomes less dense and rises.
- When the heated material reaches the top of the mantle, it cools, becomes denser, and sinks back down.
- This cycle repeats, creating a convection current that transfers heat from the core to the upper layers of the Earth.
This process of heat transfer is known as convection.
