Cold air is denser than warm air.
Warm air is lighter than cold air, that means that warm air will rise and the cold air will sink.
cold air sinks as denser - warm air rises
a difference in density
It causes convection currents because there is hot air and cold air.The hot air will will rise and the cold air will sink. then the cold ari will rise and the hot air will sink. it all changes.For instance, the hot air after it rises will sink down adn become cold air. The cold air after it sinks, it will become hot air and rise.
Cool air tends to sink, while warm air tends to rise.
Hot air is lighter while cold air is heavier. This results in warm or hot air rising and cool or cold air falls.
The cold air will sink.
Differing air temperature causing cold air to sink, and warm air to rise is the main cause of air movement.
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
rise because of it's density
Density. You can figure out the details using the ideal gas law.
causes warm air to rise and sink
Because warm air is less dense then cool air.
the warm air will rise
The cold air pushes under the warm air.
Warm air is less dense, which means it is lighter. Cold air will displace warm air causing warm air to rise.
It tends to rise because it is warm air
the sun cause un= heating of the earth making warm air to rise and cold air to sink. now you have wind.
The cool air will sink and the warm air will rise.
This is a cold front.
when a warm and cold air come in as a contact it is like cold air is heavier than warm air so it sinks forcing lighter warm air to rise
Cold air is more dense than warm air. This is why cold air masses tend to descend, and warm air masses tend to rise.
Because Warm air is less dense.
Warm air rises. Cold air sinks.
