Why does oxygen occur naturally?
It is a byproduct of the life processes on Earth. Earth's early atmosphere contained no Oxygen, but Earth was slowly Terra-formed by life and obtained an Oxygen rich atmosphere.
Do Alkali earth metals react with oxygen?
Alkali earth metals react with oxygen to form basic oxides.
Which gas in earth's atmosphere tells us that there is life on earth?
Oxygen, Nitrogen and Carbon dioxide, in that order. The most important element to sustaining life is Oxygen.
What will happen if there is no oxygen on earth?
You will die
Where and when was oxygen discovered?
Oxygen was discovered by the very first species on planet Earth.
What is inferred to be the main source of the free oxygen that first entered earth's atmosphere?
oxygen producing organisms
How is an aquarium like the earth?
merchanical source of oxygen
The primary source of oxygen for the earth's atmosphere?
Plants
What is hypothesized to be the early source of free oxygen in Earth's atmosphere?
cyanobacteria
Is the rain forest the main ecosystem on earth?

Hypothesized to be the early source of free oxygen in Earth's atmosphere?
photosynthesis by cyanobacteria
The idea that earth is composed of layers was inferred?
By God and nature.
What is needed to start a fire?
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
Who correctly explained about the center of the Earth?
Jules Verne! Can be inferred from his book(A Journey to the Center of the Earth)
What provides all the oxygen available to sustain life on earth?
Plants. The largest single source of oxygen comes from the Taiga as far as I know.
Why was oxygen absent from earth's early atmosphere?
Oxygen is an extremely chemically active element, which is why things can burn in our current atmosphere. In the early Earth, all the oxygen had reacted with other chemicals in the environment, so that there was no free oxygen. Only later, when photosynthesis was used by green plants, was there a source of free oxygen.
