At the ultimate effect, gravity is the force behind moving air.
But only because the Sun warms the air, and as the warmer air rises, more dense air moves in to take its place.
And there we have a complex interplay of the air warmed by the sun in the east, will be replaced by cooler air from the west. Hence the prevailing westerly winds.
And the next thing interacting is the Coriolis forces, which because of the rotation of the Earth, cause low pressure systems to form, and these rotate clockwise in the Southern Hemisphere, and anti-clockwise in the northern hemisphere. And the opposite directions for the anti-cyclones, the high pressure systems.
There is a philosophical question as to whether less dense air rises, or dense air sinks.
Very simply explained; air movement (wind) is caused by an exchange of heat.
In our present world, if the global temperature is rising, then as a minimum, there is an increase in the energy of the atmospheric system. This will lead to greater energy interchange between the various regions. Meaning greater variability.

∙ 10y agoAir moves (wind) die to differences in air pressure.
Convection or up liftment of air due to warming (such as at the tropics), causes a low pressure to form at the earths surface. Cool air flows in from the sides to replace it, causing wind. The warm convection air cools and descends displacing other air.
Added to this is Coriolis force (the rotation of the earth), these all cause the movement of air.

∙ 12y agothe answer is that air does move every part of the earth.To prove it,i can ask you that from where do we get oxygen?the answer will be that air contains oxygen so,if there was not any oxygen,how could we breath?we can breath because there is air moving around us.

∙ 12y agoyes it can because the wind is full of air that has a lot of pressure.

In which direction does an air mass always move?
Towards a region of lower pressure.
How do prevailing winds affect movement of air masses?
they move in the direction the wind is moving
What direction do convection currents move?
Warmer material in a convection current rises upwards.
Why do prevailing winds affect the movement of air masses?
because they move in the same direction of the wind...
In which general direction is the hot and dry air mass most likely to move?
the hot and dry air mass are most likely to rise
What direction does the air move?
Everywhere
Why did the smoke move first in an upward direction and then a downward direction?
positive air pressure then hit a negative air pressure.
How do hovercrafts move on water?
A hovercraft can move on water by forcing air downward. The hovercraft will be lifted by the air. The craft can move by rotating the Jets of air in the direction you want to go.
What direction does air above a heated surface move?
in a upward motion
In which direction does an air mass move?
Towards a region of lower pressure.
Why do freely suspended balloons move towards while blowing air?
If the balloon is exhausting air, then it will move in a direction opposite to the exhaust gas.
When atoms are moved by radiation in what direction do they move?
radiation can travel through air
In which direction does an air mass always move?
Towards a region of lower pressure.
In which direction does cool air move by water?
It will always move from an area of higher pressure to an area of lower pressure.
How does pressure cause air to move?
Pressure cause air to move because all the weight pushes up or down and causes it to go the opposite direction.
How do prevailing winds affect the movement of air masses?
they move in the direction the wind is blowing.
How do prevailing winds affect movement of air masses?
they move in the direction the wind is moving
