because the air mass decreases
The atmosphere
The troposphere is the most dense since it is closest to the surface of the earth and has the highest pressure.
No, the pressure decreases and you go higher into the atmosphere because the "air" is less dense....there is more space, but less molecules interacting with one another. Nearly half of the atmosphere's mass is contained to the first 18,000 FT (near 500mb) which is also a function of both gravity and the structure of chemical components within layers of the atmosphere. I hope that helps a little.
The atmosphere becomes less dense as altitude increases because there is less weight on the air molecules,making them less compressed. The air at a low altitude is denser because it is pressed down by all of the weight of all the air molecules above it.

it becomes more denced because the higher you get in the atmospherethe wind becomes denced
the exosphere, which is the highest layer of Earth's various layers of the atmosphere. it is the least dense because it is so high up the molecules are spread apart a lot.Type your answer here...
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
The air becomes less dense.
Basically, the higher you get in the atmosphere, the less dense it gets. It's the exosphere.
It becomes less dense.
The Earth's atmosphere declines with altitude.
the density and temperature of the layers. The farther you go up, the less dense each layer is.
The outside layers of the atmosphere are very cold, as they get little heat from the Sun. The surface is unreachable beneath the hot, extremely dense lower atmosphere.
