Wind is caused by differences in air pressure. An offshore breeze is the result of high pressure over land, and low pressure over the water. The high pressure air moves toward the lower pressure air. Or...if you just had this question on a test in the Ebus workbook, then the correct answer is B) Land mass has cooled down.
Most likely, yes. Falling pressure means that warm air is rising and warm air can hold more water vapor than cooler air. When warm wet air rises, it cools and this often results in cloud formation and possibly precipitation.
The thing that is low pressure is air. When a meteorologist says that there is an area of "Low Pressure" he is saying that there is a low air pressure in an area or, more exactly, that there is less air per cubic unit than there is in surrounding areas. So, if neutrally pressured air met with low pressured air the neutrally pressured or comparatively condensed air, a.k.a "high pressure" air would fall downward until it reached a state of equilibrium. And attaining equilibrium by both mixing with the surrounding air and falling to an altitude of similar air pressure.
All currents are caused by differences in pressure.
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
When pressure differences are small you get light winds.
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.

I have a science test this week and was wondering what causes air pressure differences on our planet?
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.
wind
Gradients
Winds.
Solar energy causes temperature differences on our planet that results in different air pressures and hence causes wind from high pressure areas to low pressure ones.
