What do scientist think was the source of the oxygen in earths atmosphere?
It came from primitive organisms early in earth's history. They were the first organisms to use photosynthesis to make food, by using light to convert Carbon dioxide and water into glucose (food) and oxygen. Since oxygen is a waste product of photosynthesis, it was released into the air. As more and more of these organisms multiplied, large amounts of oxygen were released into the air, forming today's atmosphere.
Why does a candle not burn on the surface of the moon?
for combustion to take place there has to be heat, oxygen and a fuel. On the moon there is a fuel (wick of the candle) and heat(your fire source) but no oxygen as there is no atmosphere which makes combustion (burning) impossible.
How does oxygen get replenished in the air?
Plants and other photosynthetic organisms in the process of making glucose (their food) from carbon dioxide and water (using light as the energy source) release the highly toxic waste product of this process called oxygen into the atmosphere.
Would guns work on the moon?
That would depend upon whether the charge used to fire the weapon had its own source of oxygen or not. The explosion is a very rapid oxidation and requires that oxygen to explode. Most modern smokeless powders contain their own oxygen source. If the temperature is hot enough, and that may be difficult in space, it should burn and allow the weapon to fire. If there is an internal source of that oxygen, a gun will fire normally in space. Because of the lack of atmosphere and reduced gravity, the bullet will travel faster and farther.
What source of energy heats the atmosphere?
The Sun
What is hypothesized to be the early source of free oxygen in Earth's atmosphere?
cyanobacteria
What is the major source of oxygen for the earths atmosphere is?
Plants
The primary source of earths atmosphere is?
Plants
How did bacteria change early earths atmosphere?
Earth's early atmosphere was primarily composed of carbon dioxide. Early bacteria used carbon dioxide as a source of fuel and as a result produced oxygen.
What is the source of radiation for both the earths atmosphere the greenhouse?
The sun.
What is the source of radiation for both the earths atmosphere and greenhouse?
The sun.
What is The primary source of most of the moisture for the earths atmosphere is?
Oceans
What is the most aboundant element in earths atmosphere?
I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
Which atmosphere gas is photosynthesis the major source of?
oxygen
The primary source of oxygen for the earth's atmosphere?
Plants
