Yeah you are right convection currents are movement of the air

How is destiny involved in the process of convection?
It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
Do winds need sun energy?
Yes. One of the factors behind the wind is differential heating of the earth's surface, which results in convection currents in the atmosphere.
What happens inside a convector heater?
A convection heater works on the principle of air convection currents circulating through its body and across its heating element. Heating element heats up the air, causing it to increase in volume and become buoyant. A convection heater can have an electrical heater element, a hot water coil, or a steam coil.
Is a radiator a thermal energy store?
A radiator in a central heating system works by convection mainly, that is air currents are set up which carry the heat around the room. Radiation also works to some extent, but is not the main way the heat is transferred, because the surface temperature of the radiator is limited to about 50degC for safety reasons. A hot radiator clearly stores some energy, the steel of the unit plus the hot water inside it, but if you shut off the water flow it will soon cool down. Radiators are designed for continuous heating, not storage.
What will happen if the heating element is near the top of an electric kettle?
The kettle will be less efficient because it won't be benefitting from the effects of convection currents. It will use considerably more energy.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
How is destiny involved in the process of convection?
It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
In a forced-air heating system the warm air circulates by convection true or false?
false
What creates the currents in the mantle of the earth?
they are convection currents, caused by the heating effect of the earths core
The main cause of global convection currents is?
uneven heating of the earth by the sun
What do convection currents resulting from uneven heating of Earth's surface form?
wind
Are a convection oven and a roaster oven the same?
I would think so because the fan would help the convection currents but... don't take my word for it, I'm not an oven expert! Hope this helps if not soz!
Convection currents in Earths mantle are believed to be responsible for?
Earth's Plates
Describe the convection currents that occur inside Earth?
Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.
In a forced - air heating system the warm air circulates by convection?
No, its forced by an electric blower...otherwise it wouldn't be forced air
What three factors set convection currents in motion?
The three factors that set convection currents in motion are: the heating and cooling of fluid, change in its density, and the force of gravity combine to set it in motion.
What are convection currents?
convectional currents in the mantle are themselves driven by the heat of the core. the heat is partly created of overlaying material. A lava lamp is a perfect example of convectional
