mostly Co2 SOME air but not much!! :$:
Mostly carbon and hydrogen in long chains. Can also have some oxygen.
No. The oxygen in crustal rock is naturally occurring. Oxygen in the atmosphere, however, is due mostly to photosynthesis.
in our air is there mostly oxygen
The mass of the Earth is mostly made up of iron and oxygen. Iron is primarily found in the Earth's core, while oxygen is abundant in the planet's crust and mantle.
Mostly carbon and hydrogen in long chains. Can also have some oxygen.
The oxygen is mostly found in the troposphere. However most of the oxygen formed OZONE is found in stratosphere. It is due to the pressure of air there and the UV rays.
False. Almost all of the oxygen on Earth is found in the oceans.
Sort of true - its mostly water which is mostly oxygen.
no its mostly carbon deoxide
Oxygen is found:In the airIn water (which is 2 atoms of hydrogen and 1 atom of oxygen)In any living organism - in blood, protoplasm, etc.In many kinds of minerals, and other compounds
