convection
Air near Earth's surface is denser due to the weight of the air above it pressing down, creating higher pressure. Additionally, higher temperatures near the surface cause air molecules to move more rapidly, spreading out less and increasing air density.
The air is thinner the higher you go.
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Air pressure decreases as you move away from Earth's surface. This is because the weight of air above you becomes less as you move higher in the atmosphere, resulting in lower air pressure at higher altitudes.
Wind is what causes the movement of water on the surface. The wind creates friction against the surface of the water, causing it to move in the same direction.
Where the air is over a parts of the Earth's Surface that is warm, the air warms. Warm air rises and as it rises it is replaced by cooler air that is sucked in from parts of the Earth's surface which are comparatively cooler. This movement causes a cyclic circulation of the air called win and weather.
air pressure is the highest near the earths surface

Pressure increases as you get closer to earth.
The process that causes water on Earth's surface to change to gas and rise into the atmosphere is called evaporation. This occurs when the sun's heat energy causes water molecules to gain enough energy to break free from the liquid's surface and enter the air as water vapor.
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
