Question

How is heat transfer involved in the movement of tectonic plates?

Answer 1

Mantle convection

Explanation:

The driver of moving plates is the mantle convection.

Convection is a heat transfer process that involves the movement of fluids from one place to another.

How does convection occur in the mantle?

• Part of the mantle known as the asthenosphere is a hot liquid. It moves slowly and does not readily flow.
• Over riding the asthenosphere is the brittle lithosphere made up of the upper mantle and the entirety of the crust.
• The asthenosphere is at a higher temperature compared to the lithosphere on top.
• In order to achieve stability and thermal equilibrium, the asthenosphere rises to the surface whereas the dense and cold lithosphere sinks down.
• This way a convective cell is set up.
• Hot materials rises to the surface because they are light whereas cold materials on the surface sinks into the asthenosphere.
• Through this the plates moves.
