GEOLOGY

Detailed explanation-1: -Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun’s heat is radiated back into space. The ozone layer shields us from the harmful effects of excessive UV radiation, which can lead to sunburn, skin cancer and eye damage.

Detailed explanation-2: -Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.

Detailed explanation-3: -Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.

Detailed explanation-4: -Photosynthetic plankton took advantage of the situation, pulling carbon dioxide out of the atmosphere and releasing large amounts of oxygen. This outpouring of oxygen 500 million years ago created an atmosphere that we would consider breathable.
