Question

In which layer of Earth’s interior does convection occur?

Answer 1

Answer:

Earth convection occurs at the mantle layer

Explanation:

The movement of less dense material  above the more dense material  is called as convection.  The mantle is the layer that lies between the core and the crust of the earth. The mantle is composed of rocks containing silicon, magnesium, oxygen,  aluminium, iron and other minerals.

The heat energy of the core is transmitted  to the rock in the lower mantle.  This makes the rock with less temperature that lies  in  upper mantle to move down slowly.  Now the rocks that are pushed up  is eventually cooled and again pushed down by the hotter rock  from the lower mantle. This is called as convection in earth’s mantle .
