How did the oxygen in your atmosphere get there?
The way the oxygen got into our atmosphere is when the green plants do photosynthesis. Green plants take in carbon dioxide, sunlight, and water to make glucose and of course oxygen. After a while, the plants did enough photosynthesis that the earth got an atmosphere .
What does the atmosphere contain that humans need?
The atmosphere contains Nitrogen, a gas that humans need to breakdown protein. Nitrogen take up 78 percent of it. Oxygen is found in the atmosphere (let's assume that you knew that). We all know what the Oxygen does... right?
How do green vegetation help to increase the quantity of oxygen in the atmosphere?
green vegetation are plants and of course plants give out oxygen and take our carbondioxide
Why the concentration of carbon dioxide and oxygen remains constant in the atmosphere?
the concentration and of carbon dioxide and oxygen remains constant in the atmosphere because when human throw carbon dioxide out of their body so plants take it and when plants throw oxygen so human take it.
What is percentage of oxygen at sea level?
no; oyxgen levels are the amount of oxygen in the air where as sea level is a reference point for people to get a good idea of how tall of how low something is
What process provides most of the oxygen found in earths atmosphere?
Growing more trees as trees take in carbon dioxide and releases oxygen that we use for breathing. So. I guess Afforestation provides most of the oxygen found in the earths atmosphere.
What causes all of the changes that take place in earths atmosphere?
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis
How does the percentage of carbon dioxide and oxygen stay roughly the same in your atmosphere?
It is because plants take in carbon dioxide and breathe out Oxygen whereas, man and animals breathe in oxygen and breathe out carbon dioxide. This cycle of life maintaines a roughly same percentage of O2 and CO2 in the atmosphere.
How is the oxygen in the atmosphere replaced?
Through oxygen cycle. Humans and animals take in oxygen and give out carbon dioxide. Plants take in carbon dioxide and give out oxygen. This ways the oxygen is circulated in the atmosphere.
Where does condensation take place in water cycle?
It takes place on Earths atmosphere =)
Where does condensation in the water cycle take place?
It takes place on Earths atmosphere =)
How much of the atmosphere does oxygen take up?
21%
What does not take place in earths atmosphere?
Black holes, super novas, and lots of other stuff
What does it take for aluminum to break down?
it takes the heat of a meteorite coming through the earths atmosphere

How did lots of oxygen then get into the atmosphere?
Plants They take in carbon dioxide Then keep the carbon to grow and give out oxygen
What percentage of oxygen can be found in air?
78% Nitrogen 20.5% Oxygen .5% Argon 1% Others for small calculations we take percentage of oxygen in air as 21%
