What percentage of oxygen is present in the Earth's atmosphere?
About 21 of the Earth's atmosphere is made up of oxygen.
What is two gases that present on earth?
The two most abundant gases on Earth are nitrogen and oxygen.
Where can you find oxygen on Earth?
Oxygen can be found in the Earth's atmosphere, making up about 21% of the air we breathe. Additionally, oxygen is also present in water molecules and within the Earth's crust in various compounds.
What process was primarily responsible for the development of the present percentage of free oxygen in the Earth's atmosphere?
The process primarily responsible for the development of the present percentage of free oxygen in the Earth's atmosphere is photosynthesis. This process is carried out by plants, algae, and cyanobacteria, which convert carbon dioxide and water into oxygen and glucose with the help of sunlight. Over time, this has led to the accumulation of oxygen in the atmosphere to its present level of around 21%.
How much oxygen is present in air?
21% Oxygen, 78% Nitrogen, 1% other gasses in out atmosphere.
What happens when there is 100 percent oxygen present on earth?
People will choke, hyperventilate and die
What happens if oxygen is not present?
you will die
What happens when oxygen is present after glycolysis?
fermentation
Did the primitive Earth have oxygen?

Which gas was not believed to be present at the time of Earth's formation?
Oxygen is believed not to be present at the time of Earth's formation.
Based on this diagram. what happens if no oxygen is present for cellular respiration?
fermentation
Where is oxygen present?
Oxygen is present in the Earth's atmosphere, making up about 21% of the air we breathe. It is also present in water bodies, where it dissolves to support aquatic life. Additionally, oxygen is found in the Earth's crust and is a component of many minerals and compounds.
What is two gases that present on earth?
The two most abundant gases on Earth are nitrogen and oxygen.
Is oxygen always omnipresent on Earth?
Oxygen is not omnipresent on Earth; it makes up about 21% of the Earth's atmosphere. It is produced through processes like photosynthesis by plants and organisms in the oceans. Without these processes, the levels of oxygen on Earth would gradually decline.
What happens to Hydrogen gas when exposed to flame?
If there is oxygen present it will burn (explosively)
Where can you find oxygen on Earth?
Oxygen can be found in the Earth's atmosphere, making up about 21% of the air we breathe. Additionally, oxygen is also present in water molecules and within the Earth's crust in various compounds.
