ans:
something hotter than surrounding air (radiator), has air surround that gets hot, and conduction, because gas molecules far away is very slow in air, so need another process to heat rest of air. Air surround radiator less dense after heating, therefore rises, creating space for more dense (colder air), which in turn contacts radiator, transfer heat, and rises, and process continues.

Heat convection does not occur in solids because?
Because the atoms do not move around. The whole idea of convection is that 'groups' of things move about. In the case of heat convection these moving groups take or bring their heat with them.
What process allows the plates to move?
convection currents and heat transfer
What direction will heat energy move when placed with a cold object?
convection
Which method of heat transfer use a medium?
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.
Heat rising from within earth causes earth's what to move?
Heat rising from within the Earth causes the Earth's tectonic plates to move. The constant rising and sinking of heat are called convection currents.

How does most heat energy in the atmosphere move?
Convection == == == ==
What are the ways heat move?
conduction,radiation,convection
Convection currents move heat more slowly than what?
radiant heat
What are the 3 ways heat can move?
conduction,radiation,convection
In convection heat causes a or a to move upward?
solid or a liquid
What happens for heat to be transferred by convection?
the liquid or gas must circulate to move the heat.
Can Heat be transferred through convection?
Yes. Convection currents move hot materials to other places.
What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
How is heat mostly moved through the troposphere?
Convection currents move heat throughout the troposphere.
What must happen to heat to be transferred to convection?
the liquid or gas must circulate to move the heat.
What must happen for heat to be transfered by convection?
the liquid or gas must circulate to move the heat.
