Is this statement true or false?

In a convection cell, cold dense material rises, while hot, less dense material sinks.

a) true

b) false

Answer: False

Explanation:

It's the opposite! Hot, less material rises while the cold, more dense material sinks

FALSE

Explanation:

The materials like magma when heated at great depth in the mantle due to the heat energy provided by the interior of the earth, it gets warm and less dense. This materials then starts to rise up due to the force generated by the magma in the upward direction. This hot magma then rises up and eventually cools due to the lowering of temperature in the upper portion of the mantle. This materials after being cooled, becomes less dense and sinks.

This process takes place in a form of a convection cell.

Hence, the above statement is false.
