How did oxygen gas become part of the atmosphere?
Oxygen gas became part of the atmosphere througha process called the Great Oxidation Event, which occurred around 2.4 billion years ago due to the activities of early photosynthetic organisms, such as cyanobacteria. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing oxygen levels in the atmosphere.
Which component of the biosphere contains oxygen that you breathe as well as oxygen that protects us from radiation?
The atmosphere in the biosphere contains the oxygen that we breathe. The ozone layer, also part of the atmosphere, is responsible for protecting us from harmful radiation from the sun by absorbing most of the sun's ultraviolet radiation.

Do leaves give oxygen?
Leaves are a part of a plant. Plants TAKE IN carbon dioxide and GIVE OFF oxygen.THEREFORE, leaves do not give oxygen. :D Leaves are however key part of the photosynthesis process.

Is it true that earth's atmosphere is composed of liquid oxygen?
The atmosphere of the Earth is a gas, not a liquid, and although it does contain oxygen, that is just one part of the atmosphere, which is mostly nitrogen.
Why is the atmosphere classed as an oxygen atmosphere?
Earth's atmosphere is mainly nitrogen, oxygen, carbon dioxide, and water vapor. Oxygen is the most reactive of these. Oxygen allows all of the life as we know it on earth. Even though oxygen is less than 1/4 of the atmosphere it is the most important part.
How did oxygen become a part of the earths atmosphere and what did this increase in oxygen levels allow?
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes
What common gas was not part of Earth's original atmosphere?
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
Which part of human body accepts oxygen directly from the atmosphere?
Eye
Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?
Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.
Where is oxygen obtained for mammals?
Obtained by Earths atmosphere which is 20% Oxygen and processed by the aveoli (part of the lung).
Why is oxygen such an important part of the earth's atmosphere?
Oxygen is necessary for most organisms to carry out their life functions.
What gas is 21 percent of earth atmosphere?
Oxygen
What hapens to the waste products of respiration?
