What is convection in terms of thermal energy transfer?

• The movement of heat from one object to another that has a different temperature when they are touching each other.

• The transfer of heat by radiation involving the carrying of energy from an origin to the space surrounding it.

• The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which results in transfer of heat.

• The process by which heat is trapped in the atmosphere by gases that form a "blanket" around Earth.
