The primitive earth's atomsphere did not contain?
Free oxygen
Which gas is lacking in the atmosphere of primitive earth?
Oxygen was lacking in the atmosphere of primitive Earth. Instead, the atmosphere was primarily composed of gases such as carbon dioxide, nitrogen, methane, ammonia, and water vapor.
The primitive earth's atmosphere did not contain?
Oxygen. The early Earth's atmosphere was composed primarily of gases such as carbon dioxide, water vapor, nitrogen, and methane. Oxygen levels increased with the development of photosynthetic organisms.
Without ozone layer the simple organic molecules that was formed in primitive Earth would be destroyed by the radiation of you-v ray Why we say that there was no ozone layer in primitive earth's atmos?
There was an ozone atmosphere on primitive Earth, but not an ozone layer which was formed further on. The primitive atmosphere on the surface of the Earth mostly composed by ozone was pushed upwards by the oxygen formed by dead organisms. That primitive ozone atmosphere on the surface of the Earth protected the forming microorganisms from the UV radiation. JamesWest09
What 4 gases where in primitive earth's atmosphere?
The four main gases in primitive Earth's atmosphere were nitrogen, carbon dioxide, water vapor, and methane. These gases were likely released from volcanic activity and other processes on the early Earth.
What gas was not present in the atmosphere of primitive earth?
Primitive Earth (Before life) contained no or very little Oxygen (element#8)According to scientific theory:Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.:)
How did earth get oxygen 4 billion years ago?
The Earth's early atmosphere did not contain oxygen until about 2.5 billion years ago. Oxygen was produced by photosynthetic bacteria and later by plants as a byproduct of their metabolic processes. Over time, this accumulation of oxygen led to the development of the oxygen-rich atmosphere that we have today.
It is significant that is not mentioned as having been abundant in either Earth's first or second primitive atmosphere?
The absence of oxygen in Earth's first or second primitive atmosphere is significant because it indicates that early life forms did not rely on oxygen for survival. Instead, these organisms likely thrived in an environment rich in gases like methane, ammonia, and carbon dioxide. This suggests that life on Earth may have evolved under different metabolic conditions than those present today.
If all life on Earth were to cease the atmosphere would revert to its primitive oxygen-poor composition and become poisonous to modern plants and animals?
true
How did primitive algae make it possible for other planets and animals to develop on earth?
Mainly by photosythesis that converted the CO2 in the poisonous early atmosphere, into oxygen.
Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
The primitive earth's atmosphere did not contain water vapor free nitrogen free hydrogen free oxygen inert gases?
The primitive earth's atmosphere contained mainly water vapor, carbon dioxide, nitrogen, and small amounts of other gases like methane and ammonia. It did not have free oxygen as it was produced later by photosynthetic organisms. Nitrogen and inert gases like argon were also present in the early atmosphere.
