When pressure differences are small you get light winds.
I have a science test this week and was wondering what causes air pressure differences on our planet?
It will remain the same. (:
yes this is true. this is also why you can get stronger winds if the pressure gradient in the atmospshere is greater
that they matter to the breezes and one happens at night and the other happens at day
Differences in moisture, temperature, and pressure cause air to move from one location to another. Upper level winds can also influence air movement closer to the ground.
When two masses that have a difference in air pressure meets they will create a storm front. When the differences in air pressure between the two masses increase the severity of the storm created will intensify.
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.
The differences in air pressure.
Air pressure varies because of the differences in air's density.
rotation of the earthpressure differentialdensity changesterrainetc.
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.

differences in air pressure
Yes. The movement of air is the result of pressure differences in the atmosphere. The day/night cycle causes differences in the temperatures further creating the pressure differences in the atmosphere ... PRIMARILY.
