All matter has mass. gravity is the attraction of objects with mass. The mass of the earth is high enough that gravity from the earth pulls the air towards itself.
When air particles press down on Earth, they create atmospheric pressure. Atmospheric pressure is the force per unit area exerted on a surface by the weight of the air above it. This pressure decreases with elevation due to a decrease in the density of the air column above.
Air weight.
Water goes from the earth into the air because of the effect of the sun on the earth which causes warm air to rise.
The difference in temperature in air causes movement as warm air rises and cold air sinks. The Earth's rotation also has a small affect.
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.
Air movement is caused by uneven heating of Earth's surface
The air in the atmosphere presses on us due to the force of gravity pulling the air molecules towards the Earth's surface. This creates atmospheric pressure, which is the weight of the air above us pressing down on our bodies.

Air pressure in the Earth's atmosphere is caused by the weight of the air above pushing down on the air below. Gravity plays a key role in this process, with air molecules near the Earth's surface being pulled downward by gravity, resulting in higher pressure at lower altitudes. Temperature and humidity also play a role in determining air pressure by affecting the density of the air.
