How does convection occur in an oven?
Air gets hot and it moves upwards in relation to the air that is not as hot
How garments can be designed to reduce the transfer of heat by convection?
clothes can be made to reduce convection by making the air tighter so convection currents can't occur or if a material is shiny heat and light will reflect off it instead of absorbing it
How does convection occur in radiators?
Convection is defined in the related link. It requires molecular movement to carry the heat away. The exposed surface of a radiator is hot and in contact with air. The air molecules, when in contact with the surface, pick up heat energy and move away, carrying the heat with them -- hence, convection. =============================
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.

What types of matter does convection occur?
Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
Which type of substance does convection occur best?
I would have thought it was air or water
Does uneven heating of air in earth's atmosphere can cause convection to occur?
yes
Does gravity affect hurricanes?
Yes. Hurricanes are driven by convection in which warm air rises. Convection cannot occur without gravity.
Could Uneven heating of air in earths atmosphere can cause convection to occur?
Yes, that's the basic cause of convection.
How do difference in air density cause convection currents?
It just happens because of the differenciation in the air density which allows the so called convection currents to occur/form. Complex I know but is the closest conclusion.
What are the condition required for each type of precipition to occur?
Clouds should form though convection of air and condensation of water vapor in the air.
Where do convection currents happen?
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
