Answer:
Temperature
In density
Explanation:
Convection is a process by which heat is transferred through a material and is caused by differences in temperature. This results in differences in density.
Convection is a form of heat transfer in fluid - gases and liquids.
During convection, a part of a fluid is heated. The heated part becomes less dense and it rises to other parts to replace the colder and denser parts.
