Answer:
True
Explanation:
Convection is a form of heat transfer that is predominantly common in fluids especially liquid and gas. 
It occurs by the movement of a part of substance from one place to another based on density and temperature differences. 
A typical convection cell is made up of a liquid that is heated. The liquid part close to the heat source becomes warmer and rises due to its low density. The part away from the heat source is more dense and begins to sink. 
This analogy is commonly demonstrated in a boiling pot of water.
