Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Burning fossil fuels adds Carbon Dioxide and other chemicals into the atmosphere and when that happens the earths atmospheres heats up and then temperatures rise, which will start to kill the plants and animals on our planet
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
Only if it was intentionally or accidentally taken into the atmosphere as part of a space exploration. Usually it's a earth-bound or animal-derived mineral that's too heavy to exist as a "free", airborne element.
there hobos!
Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.

79% Nitrogen, 20% Oxygen and 1% argon, Carbon Dioxide and other trace gasses.
gravity acts on the gas, just like all other things on the planet.
Often Venus is called Earth's sister planet. This is because they are similar in size. However, their other properties such as atmosphere, temperature, etc are different.
what is the basis for the division of earth's atmosphere
Earth's atmosphere is made up of gases surrounding the planet, retained by gravity. The atmosphere contains nitrogen, oxygen, argon, carbon dioxide and other gases in small amounts as well as water vapor.
Because it is the only planet that we know of having a atmosphere
