Gravity ! The gravitational pull of the Earth 'traps' the atmosphere close to the ground.
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
Oxygen usually exists as a diatomic molecule, O2, in the Earth's atmosphere.
93 million miles (they only exist in the Earth's atmosphere).
Inert gases exist in the atmosphere; helium exist also in metane and some rocks.
An atmosphere is a layer of gas that is part of a planet, and usually surrounds it solid part, if there is a solid part. so for each planet, there is one and only one plant in its atmosphere. The earth is the only planet in the Earth's atmosphere; Mars is the only plant in the Martian atmosphere; etc.,
What caused the Earth's atmosphere to exist?
could water exist as a liquid if we don't have a atmosphere
It is found in the earth's atmosphere.
Nitrogen is about 79% of the Earth's atmosphere.
In the Earth atmosphere hydrogen exist only as traces: 0,000055 %.
Nitrogen is about 79% of the Earth's atmosphere.
Noble gasses do not exist in large amounts in the earth's atmosphere. The noble gases in total sum up to less than 1% of the gasses in the earth's atmosphere.
carbon exist in earth crust as 0.02% and in atmosphere 0.03%

Oxygen usually exists as a diatomic molecule, O2, in the Earth's atmosphere.
93 million miles (they only exist in the Earth's atmosphere).
The Earth's atmosphere remains close to its surface due to gravity that keeps the gases from escaping into space. The atmosphere is held in place by the Earth's gravitational force, allowing it to envelop the planet and provide the necessary conditions for life to exist.
