Why does the ozone layer protect the earth?

Answer 1

Ozone absorbs UV-B. UV-B would otherwise damage the DNA of all DNA-based life on / near Earth's surface.

ozone is the chemical in our atmoshere that traps heat from the sun. It acts as a greenhouse, sunlight can come in but it can't go out. Ozone protects Earth by keeping it warm. Ozone is a protectant in the upper atmospere but if found in the lower atmoshere where we live, it is poisonous. Global Warming is caused by having to much ozone in the atmoshere. So in some ways ozone protects Earth by keeping it warm, but it could be a danger to Earth by keeping it too warm.

Answer 2

The ozone layer protects the Earth by absorbing and filtering out harmful ultraviolet (UV) radiation from the Sun. This helps to prevent skin cancer, cataracts, and other negative health impacts in humans, as well as protecting ecosystems and wildlife.

Answer 3

The Ozone layer protects us from the harmful ultraviolet radiations of the sun which can cause serious damage to the human life causing eye cataract, skin cancer and depressed immune system.
Basically UV-rays. UV-rays convert Oxygen (O2) to Ozone (O3). And Ozone blocks UV-rays. Ozone will eventually fall back to Oxygen. So the Ozone layer is pretty much selfsustaining.

Answer 4

ozone is poisonous and we are lucky that it is not stable nearer to the earth's surface. but it performs an essential function where it is found. it absorbs harmful radiatios from the sun. this prevents those harmful radiations from reaching the surface of the earth where they may damage many forms of life!

Answer 5

Ozone layer serves a beneficial role by screening out the sun's harmful ultraviolet rays, expose to which can threaten the health of humans and wildlife, and reduce agricultural productivity.

Answer 6

Ozone protects earth by absorbing UV rays. these are high frequency radiations that can harm the living organisms.

Answer 7

See "What does the ozone layer do?"

Answer 8

Ozone layer protects us from UV rays of Sun,which are harmful for our skin.

Answer 9

It protects earth because it does not let the sun's rays come and burn the whole entire earth.

Answer 10

Ozone layer blocks the UV rays. These are fatal rays of the sun.
