What is the atmosphere 4 billion years ago?
The atmosphere 4 billion years ago was composed primarily of carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia. It lacked significant amounts of oxygen compared to the current atmosphere. The early atmosphere was likely the result of volcanic outgassing and impacts from comets and asteroids.
What were the gases on earth 4.4 billion years ago?
4.4 billion years ago, Earth's atmosphere likely consisted of gases such as carbon dioxide, water vapor, nitrogen, and traces of methane and ammonia. There would have also been volcanic outgassing contributing to the composition of the atmosphere at that time.
How does sunlight indirectly generate coal?
It powered the plants until they died millions of years ago, to eventually become coal.

Is there less oxygen in our atmosphere now than there was 20 years ago?
Well, friend, the amount of oxygen in our atmosphere has actually remained quite stable over the past few decades. Mother Nature has a way of balancing things out, so you can breathe easy knowing that the air you're breathing is just as oxygen-rich as it was 20 years ago. Just take a deep breath and appreciate the beauty of our world around you.
Does mars contain a magnetic atmosphere?
no, but we think it might have done many millions of years ago
Where was the ozone layer invented?
In the atmosphere. Hundreds of millions of years ago.
Is the oxygen content of the atmosphere lower higher or about the same as it was millions of years ago?
Lower .
Is the current oxygen content of the atmosphere lower higher or about the same as it was millions years ago?
Lower .
Did fossil fuels contain kinetic energy stored millions of years ago?
No, not kinetic energy.
Is the current oxygen content of the atmosphere lower or higher or about the same as is was millions of years ago?
About the same. About a half billion years ago it was significantly higher, and more than a billion years ago it was lower, much lower. Before 1.5 or 2 billion years ago there was no free oxygen in the atmosphere, before 3 billion years ago there wasn't any.
Millions of years ago what city had the same name as today?
There were no cities millions of years ago.
When were humans on earth?
millions and millions of years ago
How many millions of years ago did the era in which you live begin?
it would be around 650 millions of years ago
When was solar energy used first?
About 4.57 billion years ago! The Wikipedia link below has a very in-depth discussion of the applications and history of solar energy.
Why was there more oxygen in the air millions of years ago?
Millions of years ago, there was more oxygen in the atmosphere due to high levels of photosynthesis by ancient plants. These plants absorbed carbon dioxide and released oxygen as a byproduct, leading to higher oxygen concentrations in the air.
Is the current oxygen content of the atmosphere lower higher or about the same as it was millions of years ago?
The current oxygen content in the atmosphere is about the same as it was millions of years ago. Oxygen levels on Earth have been relatively stable over long periods due to the balance between oxygen production and consumption by various processes such as photosynthesis and respiration.
