Nitrogen. Oxygen comes in second.
The earth is protected by the atmosphere which deflects some of the radiation that comes from the sun.
The layer of atmosphere closest to the earth's surface is troposphere. The next layer is stratosphere which contains the ozone layer. After that comes the mesosphere, Ionosphere n exosphere.
The air at any given layer in the atmosphere is compressed by the weight of the air above it. As you go up, there is less air wieghing down from above, so the surrounding air is less compressed.
The black tiles are heat shields which help protect the shuttle from burning in the atmosphere. Shuttle comes glides down on it's belly so the shields are only covering the bottom.
No it does not. Atmosphere comes from the earth itself.
The one that comes to mind is humidity.

Burning fossil fuels
Nitrogen. Oxygen comes in second.
AIR. Explanation: Air is not a part of the Hydrosphere, as it comes in Atmosphere.
100% of it comes from the atmosphere.
The CO and CO2 comes from burning fossil fuels, and is released into the atmosphere in the smoke.
If you are referring to water vapor in the atmosphere, most comes from the largest water source on the planet, the oceans.
