What are the 5 most used elements on earth?
Carbon, oxygen, nitrogen, iron and silicon.
What describes oxygen?
Oxygen is a chemical element with the symbol O and atomic number 8. It is a colorless, odorless, and tasteless gas that is essential for life on Earth, as it is used in cellular respiration to produce energy. In its diatomic form (O2), oxygen makes up about 21% of Earth's atmosphere.
What is oxygen used for and why?
Oxygen is used by living organisms for cellular respiration, a process that converts nutrients into energy. It is also used in combustion reactions, such as burning fuels. Additionally, oxygen is essential for maintaining the ozone layer in the Earth's atmosphere, which helps protect life on the planet from harmful solar radiation.
How much time would it for earth to run out of oxygen with no plants and trees?
Well, In answer to your question plants under go photosynthesis which is the chemical conversion of light and nutrients into food glucose. In photosynthesis plants take in CO2 through their stomata or pores in the underside of their leaves and combine it with water and light to produce glucose, a sugar that is used for food. This is the basic reaction below. Plants do not require oxygen to grow in fact they produce it so, in answer to your question a plant without Oxygen will do fine provided it has access to light, water and a few other essential nutrients.
Where did the first oxygen molecule come from on Earth?
It is unsure were the first oxygen molecule came from came from, but my bet was that it was from the process "Outgassing" in which Water, Carbon Dioxide, and other fluids, were spewed out of volcanoes. The Carbon Dioxide was used by Cyanobacteria, or Stromatolites(sp?),in photosynthesis, thus producing oxygen.

How much garlic is used in France?

What are the 5 most used elements on earth?
Carbon, oxygen, nitrogen, iron and silicon.
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.
How much oxygen should be used in an incubator?

How the sun is used on the Earth?
