Introduction
Today you will be learning about What really Makes Our Atmosphere? What really makes up our Atmosphere? our Atmosphere is made up of nitrogen, and oxygen makes up 21 percent. The remaining 1 percent is a combination of argon, water, carbon dioxide and other gases. The Earth's atmosphere is the only atmosphere in the solar system where there is plentiful free oxygen. Down below are 10 facts about our Atmosphere.
1) Acid rains form when sulfur dioxide or nitrogen oxides combine in the atmosphere with water vapors, forming acids
2) The frequency of skin cancers is increased by the thinning of the ozone layer.
3) The existing gases in the atmosphere must retain the heat infrared rays delivered by the sun radiation, reflecting them back to Earth. Without it, the Earth would be so cold that life would not be possible.
4) The biosphere is the part of the troposphere where life can exist. This goes upwards, from the Earth's surface to the maximum height where birds can fly.
5) The thermosphere is made of the ionosphere and magnetosphere.
6) Atmosphere is made of 4 layers: troposphere, stratosphere, mesosphere and thermosphere.
7) In the ionosphere, sun radiations cause ionization: the particles are electrically charged.
8) Magnetosphere is located above the ionosphere, at the external limit of the Earth's magnetic field.
9) Atmosphere's balance is menaced by human activity, which causes greenhouse effect, global warming, air contamination, ozone belt destruction and acid rains.
10)About 20 % of the Earth's population breathes severely contaminated air, especially with carbon monoxide and sulfur dioxide resulting from industrial processes.
