cause without cold air then we will have air pollution
because of nature !
the cold air pushes the warm air up and forms cumulus clouds
The cold air will sink.
cold air
A cold front develops when a cold air mass advances, lifting the air in a warm air mass.
A cold front brings in cold air. The cold air causes warm air to rise quickly. The rising air forms cumulus clouds. There is often heavy precipitation at a cold front.
Cold air increases air pressure
cold air is heavier than the warm air warm air has low water so it is hot and low heavy but cold air has a lot of water so it cold and heavy
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
the cold air pushes the warm air up and forms cumulus clouds
The cold air will sink.
Cold Air
There is really nothing interesting about cold fronts. Cold air is overtaking warm air. Since cold air is denser than warm air, cold air goes under a warm air mass.
The cold air is denser, so cold air usually sinks down, and warmer air will float to the top.
Cold air increases air pressure
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
TEMPERATURE Cold air is denser
