Which best explains the inability for life to exist in Earth’s early atmosphere? Check all that apply.
1.There was insufficient energy from material collisions to change their density.
2.High temperatures during Precambrian time caused surface water evaporation.
3.Volcanic eruptions and comet collisions added different gases to the atmosphere.
4.Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
5.The oxygen content in Earth’s atmosphere was too low to support cellular processes.
Answers
The earth in its early days was nothing like the earth of today where there are abundant life and oxygen.
Back then earth was a violent place with volcanic eruptions and extremely high temperatures.
One of the things hostile to life was that the oxygen content in Earth’s atmosphere was too low to support cellular processes.
We are gifted because we have earth which has evolved to support life forms on it. Yes, it evolved. Because there was no life existed on the plant in its early times when the plant was in its evolution progress.
Earth begun to form before 4.6 billion years. Since then, the earth had approached and witness many catastrophic events and extinctions. Earth formed as a molten planet, now we call the period of molten earth as Precambrian period. Temperature was high as unimaginable. There were some frequent volcanic explosion that spitted out lava over miles.
When earth begun to take a solid form there was on free oxygen in it. The water droplets in the atmosphere kept evaporating because of the temperature which prevented the formation of solid ice or water.
Hence, from the given options, option (2 and 5) explains the inability of life to exist on earth’s early atmosphere.
