How do differences in air density cause convection?
Less dense rises, more dense drops down.
What is the transfer of energy that occurs due to density differences in the air?
Convection.
What is the transfer of heat causing differences in air density called?
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 is convection flow?
A convective flow is the motion of a fluid due to differences in density. These differences in density commonly occur due to temperature gradients. For example the circulating air flow in a room with a hot radiatior.
What is difference between free and forced convection?
free convection : the transfer of heat resulting from differences in density of air, that thereby causes the flow of air. mechanical convection the transfer of heat resulting from a blower or fan that actively forces heated air throughout all areas
How is density involved in convection?
In convection less molecules occupy large volume as in air to reduce the density.
Why does convection happen in the atmosphere?
For the same reason that it happens in other fluids. The hot air (in this case) has a tendency to rise, and colder air, to sink, due to differences in density.
What does convection air have to deal with density?
Hot air has less density and will therefore move upwards.
Rising air is called what?
Convection. Convection is the process where a fluid (liquid or gas) moves and transports heat due to hotter fluid rising and cooler fluid sinking due to differences in density.
Why do and breezes occur?
Convection currents cause the air to rise when heated. This causes the air pressure to become lower on the surface, which then pulls in air from nearby regions, which is felt as wind.
How does air density affect convection in the atmosphere?
Less dense (warm) air rises. More dense (cool) air sinks. The two put together are convection.
