How did molecular oxygen (O2) enter Earth's atmosphere?
Molecular oxygen (O2) entered Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms, such as cyanobacteria, around 2.4 billion years ago. These organisms released oxygen as a byproduct of converting sunlight, water, and carbon dioxide into energy. Over time, the accumulation of oxygen in the atmosphere led to the development of the oxygen-rich atmosphere we have today.
Why carbon can not enter the atmosphere?
Carbon can enter the atmosphere. It moves in and out of the atmosphere through the earth's regular carbon cycle.What it can not do is enter as pure carbon. Carbon is a solid in it's natural state and solids fall out of our atmosphere. Carbon must mix with a gas, such as oxygen, to create another gas, carbon dioxide, to enter the atmosphere.
What percentage of the Earth's atmosphere is composed of oxygen?
About 21% of the Earth's atmosphere is composed of oxygen.
What are he two main components of the atmosphere?
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
What percentage of oxygen is present in the Earth's atmosphere?
About 21 of the Earth's atmosphere is made up of oxygen.
When does oxygen enter the atmosphere?
When plants finish Photosynthsis
Does oxygen can enter the atmosphere during cellular respiration or photosynthesis?
Oxygen is released into the atmosphere during photosynthesis when plants use sunlight to convert carbon dioxide and water into glucose and oxygen. During cellular respiration, organisms take in oxygen and release carbon dioxide into the atmosphere.
When does more oxygen enter the atmosphere daylight or night?
actually, more at night
Oxygen began to enter the atmosphere of the early Earth as a result of?
hot air .dude that is easy
Can oxygen can enter the atmosphere during photosynthesis?
Yes oxygen enters the air during photosynthesis after the plant has produced sugar it releases oxygen
Does photosynthesis allow carbon to enter the atmosphere?
photosynthesis takes carbon dioxide out of the atmosphere and recycles it to make oxygen. that is why trees are very important to the earth

How can you maintain oxygen in the atmosphere?
Well to maintain the oxygen in the earth atmosphere you need to make sure that the level of global warming is decreasing and less fumes will be able to make up the ozone layer. With a thinner layer around the earth this means that oxygen will be able to enter and exit the earths surface, allowing oxygen to still stay in the atmosphere.
What is the oxygen content of the atmosphere?
The atmosphere is 79.9% oxygen.
What percent of the atmosphere is oxygen'?
21% of the atmosphere is oxygen.
How does oxygen enter the atmosphere cellular respiration or photosynthesis?
Photosynthesis produces water and oxygen plus energy. It uses carbon dioxide and water to begin the process.
How did oxygen first enter earths athmosphere?
Oxygen first entered Earth's atmosphere through the process of photosynthesis by early cyanobacteria and other photosynthetic organisms. These organisms produced oxygen as a byproduct of their metabolic processes, gradually increasing the amount of oxygen in the atmosphere over millions of years.
