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!
What gas molecule found in Earths atmosphere is made up of three oxygen atoms?
The gas molecule is ozone (O3). It is formed when oxygen (O2) molecules are split apart by ultraviolet radiation in the upper atmosphere and then recombine to form ozone. Ozone helps to protect Earth from harmful ultraviolet radiation from the sun.
Why percentage of nitrogen in air is higher?
That's simply the way earth's atmosphere evolved. And fortunate for us - if the earths atmosphere was 100% oxygen, the planet would have burst into flames long ago! Earth's atmosphere is 79% Nitrogen.
Was there oxygen in the early earths atmosphere?
It is believed that the early Earth's atmosphere did not contain significant amounts of oxygen. Oxygen began to accumulate in the atmosphere around 2.4 billion years ago due to the emergence of photosynthetic organisms.
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.
What gas is the largest component of earths present atmosphere?
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
What three gasses present in Earths atmosphere absorb solar radiation?
Carbon dioxideMethaneNitrous Oxide

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 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.
What is the approximate percent of oxygen by volume present earths lower atmosphere?
Oxygen makes up about 21% of Earth's lower atmosphere by volume.
What is the approximate percent of oxygen by volume present in earths lower atmosphere?
The approximate percent of oxygen in Earth's lower atmosphere is around 20.95% by volume.
WHAT IS THEAPPROXIMANT PERCENT OF OXYGEN BY VOLUME PRESENT IN EARTHS LOWER ATMOSPHERE?
The approximate percentage of oxygen in Earth's lower atmosphere is around 21% by volume.
Where did the earths present atmosphere originate?
Earth's present atmosphere is believed to have originated from volcanic activity early in the planet's history. Volcanoes released gases such as water vapor, carbon dioxide, and nitrogen, which eventually formed the atmosphere over billions of years.
Does the density of the earths atmosphere increase with altitude or decrease?
The density of Earth's atmosphere decreases with altitude. As you move higher up in the atmosphere, there are fewer molecules of gases present, leading to lower density.
