How did oxygen come to make up 21 percent of earth's atmosphere?

Answer . When life first came about 3.5 billion years ago, there most likely was no oxygen in the atmosphere. This fact is indicated by iron in rocks formed during that time: in an oxygen environment, Fe2+ oxygenates to Fe3+, or rust. During that time, there was no evidence for rust. . Plants ev ( Full Answer )

The atmospheric oxygencomes from the decomposition of water and carbon dioxide byorganisms that use photosynthesis to mak ( Full Answer )

What planet has an atmosphere closest to earth's atmosphere?

None of them are all that close! Mars would perhaps be as good as it gets, but stay away from all planets farther away than ours unless you love sulfur clouds and acid rain so strong on Venus that it would melt anything that enters it.

How is the earth's atmosphere different from the atmosphere on venus?

The atmosphere of Venus consists mainly of carbon dioxide, and a small amount of nitrogen. The thick cloud cover is composed of sulfur dioxide and sulfuric acid droplets. Because of the dense atmosphere, the surface temperature ranges from 750 to 930 degrees Fahrenheit (398 to 498 Celsius). The surf ( Full Answer )

Where did all the gases in the earth's atmosphere come from?

Scientist theorize that bacteria with chlorophyll in them slowly but surely began to multiply. And as they did, they photosynthesized enough to create an entire atmosphere. (as you know oxygen is a byproduct of photosynthesis)

How does carbon dioxide get into Earth's atmosphere?

It is trapped in a lot of the things we burn as fuel (e.g. coal and oil) so when we burn it the carbon dioxide is released and goes into the atmosphere. Other human activities that add CO2 to the atmosphere include deforestation and cement manufacture. This accounts for about 3% of all annually prod ( Full Answer )

How do volcanoes change the earth's atmosphere?

Well it all depends on the size of the volcano. For example there was a volcano so big that when it erupted itreleased tons of dust that it almost covered the whole entireworld. The dust particles blocked the rays from the sun making theearth drop in temperature for several weeks.

How have volcanoes affected the earth's atmosphere?

The ash from volcanoes has a big effect on both the air and land. Not only do volcanoes spew out ashes, volcanoes let out gases which can be very harmful. The gases that are let out, are the same as some of the ones we produce,like carbon monoxide, carbon dioxide and sulfur oxide. Thanks (14 yrs ( Full Answer )

Yes. We have sent people beyond Earth's atmosphere.However, inorder to survive they must take air with them.

How does the increasing carbon dioxide level in the atmosphere influence the amount of energy leaving earth's atmosphere but not the quantity coming from the sun?

Radiation from the sun comes to earth in the form of ultravioletwaves.
