Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
How much of the earths water is fresh water and how much is for drinking?
3% is fresh, but 1% is for drinking.
How much of the worlds water is suitable for human consumption?
3% of the earths water is freshwater.
How does earth atmosphere make conditions on earth on suitable for living things?
REASON ONE: ATMOSPHERE Earth has a breathable atmosphere. Oxygen is the gas that is required for the life of most creatures. This is present in Earth's atmosphere, along with nitrogen, and in water, along with hydrogen. Oxygen is constantly put into the atmosphere by plants and trees. Fortunately, Earth's atmosphere does not contain much carbon dioxide, a poisonous gas which makes up most of the atmosphere of planets like Venus and Mars. In densely-populated areas, carbon dioxide is more present. This is because cars and factories produce it. This causes the air to be polluted. The Earth's atmosphere is kept on the planet by its pull of gravity. Mars and Mercury are too small to keep atmosphere. As a result, Mercury has no atmosphere, and Mars' atmosphere is very thin, containing gases which have not managed to escape into space yet. Earth's atmosphere is thick enough to prevent poisonous rays of radiation from getting through it (this is what has happened on Mars).
How much of the earth's atmosphere is made up of nitrogen?
78% of earth's atomospere is made up of water
What is the relative abundance of the element of argon?
Argon is the third most abundant gas in the Earth's atmosphere, making up about 0.93% of the atmosphere. It is present in much lower concentrations compared to nitrogen and oxygen. In the Earth's crust, argon is not as abundant as in the atmosphere, with only trace amounts found in minerals.
What takes up 1 percent of the earths atmasphere?
Assorted gases such as argon, the rest of the atmosphere is pretty much just Oxygen and Nitrogen.
How much argon is in Venus's atmosphere?
In both lunar rocks and the atmosphere of Venusthe Argon 40/argon 36 ratio is 1:1 while in the atmosphere of Earth argon 40 is 99.6%
How much percentages of argon is in the air?

What does argon have in common with air oxygen and nitrogen?
Argon, oxygen, and nitrogen are all gases found in the Earth's atmosphere. However, argon is an inert gas, while oxygen and nitrogen are reactive gases. Additionally, argon is present in much smaller quantities compared to oxygen and nitrogen in the atmosphere.

Argon makes up about 0.93% of Earth's atmosphere by volume.
How much Argon and nitrogen is there in the martian atmosphere?
the Martian atmosphere is made up of 95% Carbon Dioxide, 3% nitrogen, 1.6% argon, and 0.4% oxygen.
