Give an example of a diatomic molecule found in earths atmosphere?
Two examples are nitrogen (N2) and oxygen (O2).
Was the atmosphere of the earth always mostly nitrogen and oxygen?
No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
Was there oxygen in the early earths atmosphere?
yes
What is methane and oxygen?
Gasses found in Earths atmosphere.
What gas molecule found in Earths atmosphere is made up of three oxygen atoms?
You are thinking of ozone.
What gases were present in earths today atmosphere?
Nitrogen
What element in earths atmosphere was not present in the far past but is present now?
The element "Oxygen".
Which gas exist in the highest concentration in the earths present atmosphere?
Nitrogen is about 79% of the Earth's atmosphere.

Two examples are nitrogen (N2) and oxygen (O2).
How did earths atsmophere change during the precambrian time?
It changed from a reducing atmosphere containing no free oxygen to an atmosphere containing oxygen. The evolution of life on Earth "terraformed" the planet.
What three gasses present in Earths atmosphere absorb solar radiation?
Carbon dioxideMethaneNitrous Oxide
What layer of earths atmosphere would be considered good ozone?
There is good ozone and then there is bad ozone. Good ozone is present in the earth's atmosphere.
Which layer of the earths atmosphere protects the earth from the ultraviolet radiations of the sun?
Ozone layer protects us. It is present in the stratospheric region of atmosphere.

What component of the earths atmosphere exists as a result of photosynthesis?
Photosynthesis converts carbon dioxide into oxygen. Therefore, much of the oxygen in our atmosphere is present due to photosynthesis.
Why can elements be produce in the sun but not in the earths atmosphere?
Many elements only form through high temperatures and pressures... both of which are present int the Sun - but not in the Earth's atmosphere.
What are earths layers and sub layers?
All of the earth's layer are present inside the atmosphere. The ozone layer is situated in the stratosphere.
