What gas was present in earths primitive atmosphere?
The primary gases in Earth's primitive atmosphere were likely hydrogen, helium, methane, ammonia, and water vapor. Over time, these gases were likely transformed by geological and biological processes into the current composition of the atmosphere.
Was the past atmosphere polluted like the present atmosphere?
In a since, yes. It contained carbon like it does today. However, the particles per million (ppm) is a much higher concentration than it has veer been in the past.
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.
How have we polluted earth's atmosphere?
The earth's atmosphere has been polluted the burning of fossil fuels that releases nitrogen oxides, sulfur and carbon monoxide in the air. Other man-made pollutants from factories also contribute to polluting the atmosphere.
What happens the atmosphere gets polluted?
Big holes in the ozone (atmosphere) appear. That's why global warming is happening.
What percentage of earth's oxygen is polluted?
None of the Earth's oxygen is polluted. Oxygen is an element and, if it is present, is in its pure form. Areas of the Earth's atmosphere (a mixture of about 21% oxygen, 78% nitrogen and 1% argon along with traces f other gases) may contain local concentrations of pollutants.)
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 has the earth's atmosphere changed since the earth began?
it has beome more polluted
What happen to the amount of oxygen present in the bodies of water if they get polluted?
Decrease
What happen to the amount of oxygen present in bodies of water if they get polluted?
Decrease
What will happen to the amount of oxygen present in the bodies of water if they will be polluted?
decrease
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.
