Oxygen is actually a byproduct of early life. With water being the birthplace of life as microbes and simple forms of DNA structures, they did not need oxygen, rather, they did the opposite of "breathing" oxygen, they excreted it. To life at that time, Oxygen was considered toxic waste, practically their feces. Slowly, over time, with oxygen being lighter than air, it seeped up from the early oceans for billions of years changing the atmosphere of the earth. By adding enough oxygen to the atmosphere, it essentially created a protective shield from the suns more deadly rays. Thus allowing life to finally migrate out of the water, and adapting to the new atmosphere. This explains why for the first 3 billion of years of creation, life was only existing in microscopic forms, and why it has recently in the earths history exploded in an era of evolution above water.
What else can I help you with?
What is the number of days that the planet 's revolve around the sun?
You would have to find the planet with the longest year and that would be your answer because as you knoe Earths year is 365 (about) days and Mercurys is 88 days so....
What is by the rotation and revolution of the planet?
the earths rotation around the sun is 365 days . hope this helps (:
What planet would take 164 of earths days to go around the sun?
There is no planet with a revolution period of 164 Earth days. Neptune, however, has a revolution period of 164.8 Earth years.
Has a planet over 5 billion years old crash into our planet?
to correct that it was around 4.6 billion years ago. scientists believe that early in earths days, a body about the size of mars crashed into the young earth flying many debree in earths orbit. it was then believed to form the moon. to correct that it was around 4.6 billion years ago. scientists believe that early in earths days, a body about the size of mars crashed into the young earth flying many debree in earths orbit. it was then believed to form the moon.
Which planet has the shortest period of revolution as measured relative to earths time?
The planet that has the shortest period of revolution is Mercury, which is 88 days. The planet with the longest revolution is Neptune, which is 165 years. Earth's revolution is the third shortest.
What is the planet earths rotation time?
About 365 1/4 days long. The quarter not counted, so to make up for the time there is a leap year every 4 years.
What was the gas in Earth's early atmosphere that was chemically converted or trapped in the rocks?
Oxygen was trapped in rocks in the very early days of earth. These rocks are known as "banded rocks". It took a long time before the oxygen was let out of the rocks.
How many days on the planet Mercury?
i think they are 586 days on the planet mercury
Why is Mercury's year 88 days if Mercury is the fastest planet and closest to the sun?
Mercury's year of 88 days is pretty short when compared to Earths 365 day year. The orbital period gets longer the further you go out. Neptune is the furthest planet out and takes nearly 165 years to go around the sun once.
What is the lenghth of earths year?
the length of earths year is 365 days, tho its not really hahaha
Which planet has 365.24 days?
The planet you live on. Earth.
In the old days what did the discoverer give to its planets?
In the early days of planet discovery, the discoverer often named the planet after mythological figures or deities. This practice allowed them to connect the newly found celestial body with larger cultural or historical narratives.
