It is produced by photosynthesis in plants.
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
Most of the oxygen in Earth's atmosphere comes from photosynthesis carried out by plants, algae, and cyanobacteria. These organisms utilize sunlight to convert carbon dioxide into oxygen during this process.
The earth is protected by the atmosphere which deflects some of the radiation that comes from the sun.
The layer of atmosphere closest to the earth's surface is troposphere. The next layer is stratosphere which contains the ozone layer. After that comes the mesosphere, Ionosphere n exosphere.
No it does not. Atmosphere comes from the earth itself.
The one that comes to mind is humidity.

100% of it comes from the atmosphere.
AIR. Explanation: Air is not a part of the Hydrosphere, as it comes in Atmosphere.
If you are referring to water vapor in the atmosphere, most comes from the largest water source on the planet, the oceans.
Whatever is in the atmosphere in the surrounding area.
Friction as the spacecraft comes into contact with the earth's atmosphere.
well sea water that comes from the atmosphere contains small concentrations of the gases in the atmosphere such as oxygen, carbondioxide, carbonmonoxide, and nitrogen. it would also contain pollutants from factories
Oxygen comes in second at 20.9463% of our atmosphere.
