because warm air move upwards and cool air due to gravity move closer to the earth surface
packed together due to higher pressure, resulting in increased density. This causes the air to become heavier and more compact as it moves closer to the Earth's surface.
Air density and pressure increase nearer the surface
The ground temperature at 5 feet below the surface is typically more stable and closer to the average annual air temperature of the region.
Air pressure is greatest at the Earth's surface, particularly in the troposphere, due to the weight of the air above pressing down on it. The air molecules are denser near the surface because gravity pulls them closer to the Earth, resulting in higher pressure. As you move higher in altitude, there are fewer air molecules above, leading to a decrease in pressure.
The air in a mine is typically more dense than the air on the Earth's surface. This is because the air in a mine is generally cooler, leading to higher air density due to cooler temperatures causing the air molecules to be packed closer together.
The air is more packed closer to the surface due to the weight of the air above compressing it. This results in higher air pressure levels near the surface.

Air density and pressure increase nearer the surface
With a higher altitude, there is a lower air pressure. This is caused by gravity pulling the gas molecules of our atmosphere closer to its surface. when the molecules are farther away from the Earth's surface the gravitational pull is weaker thus making the atmosphere thinner higher up and thicker closer to the surface.
This phenomenon, known as underwater refraction, occurs because light travels at different speeds through water and air. When light passes from water to air, it bends away from the normal (perpendicular line), causing objects to appear closer to the surface than they actually are.
Air closer to Earth's surface is warmed by the ground, which absorbs and retains heat from the sun. This warming process is known as conduction. In contrast, the air high above the surface has less contact with the warm ground and is primarily heated through radiation from the sun, making it cooler.
Objects underwater appear closer than they actually are due to the refraction of light. Light bends as it passes from water to air, making objects underwater appear closer to the surface than they really are.

The air in your lungs expands in volume as you get closer to the surface of any water you swim in. This is because the air was compressed when deeper due to the pressure of the water around you. This is why when scuba divers always exhale while ascending to avoid rupturing their lungs as the air expands.
As altitude decreases, air density increases. This is because air molecules are more compressed closer to the Earth's surface, resulting in higher density at lower altitudes.
A shape with a large surface area facing the direction of motion, such as a flat surface or a sphere, experiences the most air resistance. This is because a larger surface area results in more air molecules colliding with the object, creating greater resistance.
