What would Earth's atmosphere be like today if life had not evolved on Earth?

It might be similar to the atmosphere on Venus, where the oxygen has combined with surface rocks and as carbon dioxide. On Earth, plants remove carbon dioxide and increase the level of free oxygen that supports animal life. This atmosphere also reduces ultraviolet radiation, which also affects the level of gases.

What gases were present in earths today atmosphere?
Nitrogen
Is the air you breathe now the same air since creation?
Creation of what, the earth? There was no atmosphere at creation. No air. The oxygen we breath today was created by living plants that populated the earth long before we evolved
How does earths atmosphere make condtions on earth suitable for living things?
You have that the wrong way round, LIVING things have changed Earth's atmosphere to make it suitable for them. When Earth first came into being, the atmosphere was NOT like it is now, it could not sustain the life that exists today. Over Geological time tiny bacterial organisms generated the Oxygen that we have in our air today, and altered the whole environment of the planed in doing so. Thus the driving factor is LIFE not the atmosphere.
Why pieces of earth's earliest crust do not exist today?
why do pieces of earths earliest crust not exist today
Why is the atmosphere the most vulnerable part of the earths environment?
Many people today assume mistakenly that the Earth is so big that we humans cannot possibly have any major impact on the way our planet's ecological system operates.
What do you think earths atmosphere would be like today if life had not evolved on earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
What is wrong with earths atmosphere today?
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
How has the earths atmosphere changed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
How has earth atmosphere changes since it first formed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
What are the two gases that existed in earths earlier atmosphere?
The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter today.
What do you think earth atmosphere would be like today if life had not evolved one earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
Why did the earth's atmosphere change after it was first formed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
What gases were present in earths today atmosphere?
Nitrogen
How is Biogeochemistry used today?
biogeochemistry is used by earths atmosphere

How did the primitive atmosphere differ from atmosphere today?
As opposed to today's atmosphere, the Earth's early atmosphere would have been quite impossible for human life to thrive in. Today the atmosphere consists primarily of Nitrogen, Oxygen, and Carbon Dioxide, but early Earth's first atmosphere was probably made of Hydrogen and Helium.
