It is called wind.
It's called wind.
The movement of air shown is due to differences in air pressure. Air moves from areas of high pressure to areas of low pressure in an attempt to balance out the pressure differences.
When pressure differences are small you get light winds.
It is called a convection.
Temperature differences is why air moves in the atmosphere. Hot air rises, cold air falls. With these temperature difference comes pressure differences and these temp. and pressure differences are what keep the air moving. Theoretically, if there were no temp. or pressure differences in the atmosphere, air would not move.
Wind is caused by differences in air pressure. When air moves from areas of high pressure to areas of low pressure, wind is generated. The uneven heating of Earth's surface by the sun is a major factor in creating these pressure differences that lead to wind.
Air pressure varies because of the differences in air's density.
I have a science test this week and was wondering what causes air pressure differences on our planet?
differences in air pressure
The term for air that is constantly moving due to differences in water and land temperature is called wind. This movement is caused by variations in atmospheric pressure and the Earth's rotation, which create differences in temperature and pressure that drive air circulation.
