without density it would be pretty hard for air to exist.
Here is a breakdown:
first of all we know air exists, and that it exists in 3 dimentions of space.
In order for something to exist there must be space in which it can exist, this is Volume (V).
Since air is a form of matter, it must have mass (m)
we now have two variables which define air's presence, m and V, mass of air (m), and the space it inhabits, (V).
since so much mass has to exist in a certain amount of space, the relationship between mass and space is proportional. You will have so many kilograms of air in so many meters cubed of space. Just as you have 12 eggs in 1 carton, or 4 tires per car, density tells you how many Kg of air per meter cubed. (in metric)
density = m/V
bottom line: any mass will have density, because it occupies space, and density simply represents how much mass is occupying how much space.
Any 1-kilogram mass near the Earth's surface.
You can convert that to kilograms (reminder: 1 kg = 1000 grams); then multiply by the value of the gravitational field, which near Earth's surface is about 9.8 newton/kilogram. This will give you the weight in newton.
The lowest level, the troposphere near the Earth's surface, has the highest pressure.

as all most of atmospheric air is present near the surface of earth.
upper earth (atmosphere)For computer answer A+ air near the earth's surface blows more slowly.
Most of the Earth's atmosphere is concentrated near the surface due to gravity. The force of gravity pulls air molecules towards the Earth, making the air denser at lower altitudes. As you move higher in the atmosphere, the air becomes less dense because there are fewer air molecules present.
The force that holds air near Earth's surface is called gravity. Gravity is responsible for pulling air molecules towards the surface of the Earth, creating air pressure and keeping our atmosphere in place.
The atmosphere near Earth's surface is heated from below primarily through the process of conduction. This occurs as the Earth's surface absorbs solar radiation and heats up, transferring this heat to the adjacent air molecules through direct contact. As the air warms, it becomes less dense and rises, creating convective currents that distribute the heat throughout the atmosphere.

The atmosphere is denser near the Earth's surface because gravity pulls the air molecules towards the ground, compressing them and increasing their density. As you move higher in the atmosphere, there are fewer air molecules above you, leading to lower pressure and density.

The atmosphere near Earth's surface is primarily warmed through the process of conduction, where heat is transferred from the Earth's surface to the air molecules in direct contact with it. Additionally, sunlight absorbed by the Earth's surface is re-radiated as heat, warming the surrounding air.
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.

Air particles are more closely packed near the Earth's surface due to the weight of the atmosphere compressing them together. As you go higher above the surface, the air becomes less dense and particles are more spread out.
