ViviExample: air near the ground on a hot day is heated by the hot surface. It therefore expands, so its density falls and it rises to be replaced by the coolder air above it. After a while in contact with the cooler air higher up it stops rising and merges with the atmosphere, so a cycle is set up. This cycle is called convection.

What is a great sentence for convection?
Convection is defined as the transfer of heat through a fluid,(liquid, or gas form) caused by motion of molecules. A pot of water on the stove, warms through the process of convection.
Which transfer of energy occurs mainly through the process of convection?
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
Which process causes the transfer of energy by air currents within the Earth's atmosphere?
convection
How does the process of convection rely on radiation?
It relys on it because convection are the air currents that have to be heated by something, so you need objects to radiate heat to heat up the air to start the current
What are 3 methods of heat transfer?
Heat (or thermal) energy is kinetic energy due to motion of atoms and molecules. It is energy that is in the process of being transferred from one object to another because of their temperature difference
