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 is The primary source of most of the moisture for the earths atmosphere is?

In what ways does water leave earths surface and enter the atmosphere?
Water leaves Earth's surface and enters the atmosphere through processes such as evaporation from oceans, lakes, and rivers, as well as transpiration from plants. Additionally, water is released into the atmosphere through sublimation from snow and ice.

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.
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.

What Forms when a meteoroid enters earths atmosphere?
Meteoroids don't enter the earths atmosphere, Meteors do. Meteoroids are the rocks that you find on the ground after a meteor penetrated the atmosphere and made it to the ground.

What happen when a asteroid when they enter the earths atmosphere?
Usually they will burn up due to the friction they encounter when they enter the atmosphere, or they will bounce off the atmosphere and be deflected into deep space.
