What gases exist today but were absent from early earth's atmosphere?
is it carbon dioxide
How did the earth's atmosphere change composition to become today's nitrogen and oxygen atmosphere?
The original atmosphere of Earth was lost when the solar wind of the early sun stripped away all the gas from around Earth. A secondary atmosphere was slowly released by volcanoes as gases were released from the molten rock. Most of this gas is carbon dioxide, but it is gradually dissolved in the oceans and precipitates out as carbonate rock instead of building up in the atmosphere.
Why do more ultraviolet waves reach earth today?
More ultraviolet waves reach earth today because the atmosphere is changing and they do not get filtered out.
Which gas is most abundant in earth's atmosphere today?
The air mostly consists of nitrogen. :)
What does our atmosphere do that makes conditions on Earth suitable for life?
You have it wrong way round, the atmosphere of Earth was created by the life on Earth. 4000 million years ago the atmosphere had no oxygen and was full of CO2, Nitrogen and Methane. However life came into existence in this atmosphere and over time has altered the atmosphere to what we have today. Therefore the composition of the atmosphere would not appear to be critical to life.
How did the primitive atmosphere differ from atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.

What is wrong with earths atmosphere today?
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.

How did earth come have an oxygen atmosphere?
Early organisms created oxygen from other gases in the atmosphere. More specifically, the methane atmosphere on Earth was supplanted by oxygen generated by microorganisms in the oceans. Today, the vast majority of our oxygen comes from the ocean - mainly plants. Earth came to have a oxygen atmostphere because that is the way God invisoned it, so thats how he made it.
Was the earth's atmosphere always the same?
No, actually it took a period of about 2.5 billion years for the atmosphere to be were it is today.
Did volcanoes create life?
After loss of the hydrogen, helium and other hydrogen-containing gases from early Earth due to the Sun's radiation, primitive Earth was without an atmosphere. The first atmosphere was formed by gases leaking out from the interior of the early Earth, which still goes on today in volcanoes. Without an atmosphere, life would not have formed.

How and when was earth's atmosphere formed?
All matter attracts particles. Therefore all matter in the universe has a form of atmosphere. This can easily be observed. On early earth (and to a lesser degree today), exhaust gases from early volcanoes largely consisted of ammonia, carbon dioxide and steam. These basic combinations of gas, using their particle constituents, also help to form other gasses.
Why do more ultraviolet waves reach earth today?
More ultraviolet waves reach earth today because the atmosphere is changing and they do not get filtered out.
