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.

What common gas was not part of Earth's original atmosphere?
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
What would happen if there is were no atmosphere on the earth?
If there were no atmosphere, life, as we know it, would never have developed on Earth.
The primary source of oxygen for the earth's atmosphere?
Plants
How do plants on earth affect the amount of carbon in earth's atmosphere?
It can regulate carbon because plants need it to live.
How did the oxygen in your atmosphere get there?
The way the oxygen got into our atmosphere is when the green plants do photosynthesis. Green plants take in carbon dioxide, sunlight, and water to make glucose and of course oxygen. After a while, the plants did enough photosynthesis that the earth got an atmosphere .

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 would happen if there is were no atmosphere on the earth?
If there were no atmosphere, life, as we know it, would never have developed on Earth.
What was the earth's atmosphere like before photosynthesis?
Without life because when plants do photosynthesis, they produce oxygen.
What changed the composition of the ancient atmosphere on Earth?
When plants and animals evolved, this made changes in the atmosphere on Earth

Where did Earth's secondary atmosphere most likely developed from?
volcanic gases
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
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.
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.
