Question

How does mantle convect?
​

Answer 1

Mantle convection occurs as described below:

Explanation:

• The mantle of the Earth is present between a layer of underlying liquid core and overlaying solid crust. The mantle is made up of layers of solid rocks in between these two layers.
• The convection in the mantle occurs when the heat in the mantle layers is passed to the surface. This effect is achieved by fluid-like motion of the rocks.
• The areas that are hotter rise in an upward direction causing a convection effect.
