Convection only occurs in due to particles moving not just heat transfer as in conduction?
Yes, convection is the transfer of heat through bulk movement of a fluid, gas or liquid. The movement can be natural caused by density differences, or can be forced.
Describe how heat is transferred from one place to another by convection?
Convection is the transfer of heat in a gas or liquid caused by differences in density, thus when molecules in the medium are heated they form a less dense gas or liquid which then rises through the cooler unheated medium, thus creating moving warm currents.
What is the difference between conduction and convection?
Conduction transfers heat by direct contact. Convection, is the transfer of heat by movement of the medium, due to difference of density caused by changes in temperature.
What is the definition of a convection?
convection is basically the up and down movement in gas and liquids caused by heat transfer.
What is heat transfer by convection caused by?
Heat transfer during convection heating is simply caused by diffuse expansion through liquid with regard to the force of buoyancy. This phenomenon can be noticed in nature as well as forced in the lab

Which describes the convection currents that drive the motion of lithospheric plates?
A continuous flow in the mantle caused by differences in density

Describe the process of convection?
Convection is caused by temperature differences, in a gas such as air, which affect the gas density in local areas thus causing movement of the gas, generally upward due to buoyancy of warmer gas compared to the average density. Thus heat from a heating element near the floor of a room can be spread through the room without any forced circulation.
What is the flow of air in a loop caused by differences in temperature and pressure called?
It's called wind.

Convection occurs when a warm liquid or gas?
Convection occurs when a warm liquid or gas moves moves into a region where the surrounding liquid or gas is a different temperature. An example of this is a warm gas rising into a region where the surrounding gas is cooler due to the lower density of the warm gas. Movement of gases and liquid due to differences in density (because of differences in temperature) is referred to as "natural convection". When the movement is caused by another force such as a pump or a fan or a mixing blade, then it is termed "forced convection".
The heat transfer caused when heated liquids or gases rise is called?
convection
What is A complete circle of moving liquid or gas caused by temperature differences?
Its called CONVECTION or CONVECTION CELL some times
Currents are caused by temperature and density differences?
deep
