Hostile, at least to life as we know it. It contained high levels of carbon dioxide, as well as water, hydrogen sulphide. Life was made up of single-celled organisms that reduced the hydrogen sulphide to gain energy and oxygen was toxic to them. Eventually single-celled organisms that performed photosynthesis evolved. These got their energy from light and converted carbon dioxide to sugars and oxygen.
Plants producing oxygen caused the first major extinction of life on earth as all the creatures that couldn't cope with oxygen were killed.
The early atmosphere of Earth was primarily composed of gases such as carbon dioxide, nitrogen, water vapor, and trace amounts of methane and ammonia. There was little to no oxygen present. These conditions changed with the development of photosynthetic organisms, like cyanobacteria, that produced oxygen as a byproduct.

What common gas was not part of Earth's original atmosphere?
Oxygen is a common gas that was not originally part of Earth's atmosphere. It was first produced by early photosynthetic organisms and gradually built up in the atmosphere over billions of years.
How do plants on earth affect the amount of carbon in earth's atmosphere?
It can regulate carbon because plants need it to live.
The earth's atmosphere probably developed from gases escaping from the interior of the earth during volcanic eruptions this out gassing also produced the earth's?
The Earth's atmosphere likely developed from gases released during volcanic eruptions. Outgassing also contributed to the formation of the Earth's early atmosphere and the oceans through the release of water vapor and other volatile compounds.
The primary source of oxygen for the earth's atmosphere?
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
Before there was any life on earth which gas was absent from earth's ancient atmosphere?
Oxygen was absent from Earth's ancient atmosphere before there was any life on Earth. The early atmosphere was composed mainly of gases like carbon dioxide, water vapor, nitrogen, and small amounts of methane and ammonia.
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which of these developed?
green plants / algae
What was the earth's atmosphere like before photosynthesis?
Without life because when plants do photosynthesis, they produce oxygen.
What common gas was not part of Earth's original atmosphere?
Oxygen is a common gas that was not originally part of Earth's atmosphere. It was first produced by early photosynthetic organisms and gradually built up in the atmosphere over billions of years.
What changed the composition of the ancient atmosphere on Earth?
When plants and animals evolved, this made changes in the atmosphere on Earth
In which natural cycle must important gas in Earth's atmosphere be fixed before plants can use it?
are you from connections academy? I am.its nitrogen cycle.
In what part of the earth's atmosphere would you find plants and animals?
You would fins plants and animals in the troposphere, where we live on earth
What gas plants contribute to the earth atmosphere?
carbon dioxide
How do plants on earth affect the amount of carbon in earth's atmosphere?
It can regulate carbon because plants need it to live.

Which have well developed atmospheres?
Only Earth and Venus has a well developed atmosphere out of the rocky planets. Note that the rocky planets are Mercury, Venus, Earth and Mars.
What speed does a space shuttle reach before leaving the earth's atmosphere?
The space shuttle reaches 17,850 mph before leaving earth's atmosphere.
Why is the atmosphere 78 percent nitrogen and only 21 percent oxygen?
There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen
