Atmospheric Factors Affecting Earth

This is my paper.

Ozone

The ozone is a layer inside the stratosphere that protects Earth from UV radiation. Without the ozone, we would all be burned due to UV radiation. Ozone depletion is when a hole in the ozone appears. This is a sign of global warming caused by smog and other gases.

Greenhouse Effect

The greenhouse effect is when light from the sun travels into a glass like containment. The light gets into the glass like containment and tries to get back out. The glass protects the light so it will never come out until the light is absorbed. This is what happens with atmosphere. The sunlight travels to Earth and tries to go back out. But the troposphere acts like the glass of the Earth. The sunlight is either absorbed into the Earth, goes back out to space, or gets absorbed into gas molecules.

London Type Smog

London-type smog was caused mainly by air pollution due to combustion of coal and emission of sulphur dioxide (SO2) and dust. Such pollution mixed with fog can produce droplets of sulphuric acid (H2SO4) suspended in the air. When in 1952, in London, the concentration of SO2 during a smog event exceeded 3.5 mg per 1m3 of the air (or 3500 ug per 1m30), it caused massive cases of decease(Note: 1mg is 0.001g; another unit is 1 ug which is equal to 0.000001 g. So 1g=1000 mg or 1000000 ug).
