Ozone layer
The ozone layer is approx. 50 km above ground, it consists of two layers, the troposphere which is approx. 20 km above the ground and the stratosphere is about. 50 km above the ground. It protects us against the sun’s harmful rays, the ozone layer had not been there would all life on Earth died out, but not right away. First, ones immune system is weakened, then perhaps we will be blind. It will also have a huge impact on the ecosystem, for example. to algae and fish breeding might collapse and there will be no food for some animals, they will die and so it goes on.
The ozone layer is composed of a mass of molecules and are degraded by different things, including CFC gases. CFCs are a few molecules in gases. One of the molecules can take up to 10 years for sunlight to destroy. Before the molecules are degraded when they kill approx. 100,000 ozone molecules. By decomposition process will be triggered a substance called chlorine which in turn attacks the ozone layer. Chlorine enters the stratosphere and attack the ozone molecules, ozone molecule and chlorine form a new molecule called klormonoxid, ozone molecules take it back and creates a one oxygen molecule and then the chlorine free to kill even more ozone molecules. CFC Gasses consists of three things: Chlorine, Flour and Carbon,
The ozone layer reflects 31% of the sun’s rays, and if it disappears, it will be much warmer on the ground. It will be impossible to live on earth if that happens.
CFC gasses be used in:
Freezer and Refrigerator
Propellant in aerosols
When dry cleaning
