The 'ozone' layer in the upper atmosphere blocks out harmful (cancer causing) ultraviolet light from the Sun.
See "What does the ozone layer do?" in the "Related questions" section below.
The ozone layer protects us from the harmful UV rays of the sun. UV rays are harmful and fatal rays.
Ozone helps to absorb the UV rays. These are the harmful rays of the sun.
Ozone is a layer of importance. It is the reason for life on earth.
Ozone umbrella is the name given to ozone layer. It is the layer of protection in the atmosphere.
the use of CFC's hurt ozone. It depletes the layer.
Some gaseous products of human activity can reduce the about of ozone in the upper atmosphere, thus decreasing the effectiveness of the ozone layer in shielding the surface of the planet from ultraviolet radiation.
Ozone layer must be protected to allow human survival. Motivation regarding human survival is enough for this.
Ozone is a layer of importance. It is the reason for life on earth.
The importance of ozone layer is up there in the atmosphere. The need to protect is due to its depletion.
The layer that affects the earth's surface is ozone. Ozone is a layer of importance.
Ozone umbrella is the name given to ozone layer. It is the layer of protection in the atmosphere.
We have to protect the ozone layer to allow human existence. This existence of ozone is the reason behind human survival.
The importance of ozone layer is very substantial. It is because of it's ability to block the UV rays.
The sun radiates large variety of radiations including ultraviolet radiations which are very harmful to the human body. The ozone layer absorbs ultraviolet radiation rays and prevents them from coming to the surface of the earth thus saving the human beings from harmful rays. This ozone layer in the stratosphere is considered to be "good ozone." The ozone layer occurring naturally in the lower layers of the atmosphere helps remove the pollutants from the surface of the earth.
Ozone layer helps to maintain the appropriate temperature. This helps plant grow and survive.
Ozone layer protects the humans. It declines the entrance of UV rays.
the use of CFC's hurt ozone. It depletes the layer.
Some gaseous products of human activity can reduce the about of ozone in the upper atmosphere, thus decreasing the effectiveness of the ozone layer in shielding the surface of the planet from ultraviolet radiation.
Ozone layer is consisted in the stratosphere layer. This layer is very protective for human population.
