To Show How the Ozone Layer Can Be Destroyed as the Responsibility of Chlorofluorocarbons ( CFCS ) for this Damage 来自 Semantic Scholar 喜欢 0 阅读量: 26 作者: W. Southerland 摘要: Ozone is a safeguard for the earth. Ozone protects the earth from a dangerous ultraviolet radiation. The ...
How does the ozone layer protect us? Why is the ozone layer in the stratosphere? How do chlorofluorocarbons contribute to the greenhouse effect? How does soil pollution affect the air? Why do CFCs damage the ozone layer? How does plastic pollution affect the air? How does ground-level ozone...
However, as our ozone layer depletes due to use of chlorofluorocarbons (CFCs), UV levels are increasing. This can lead to health effects like skin cancer [source: EPA]. X-rays: X-rays are very high-energy light waves. We're most familiar with their use in a doctor's office, but X...
This layer is made up of other atmospheric gases like nitrogen, oxygen and argon but significantly higher concentration of ozone. Lower traces of other gases found are carbon dioxide, neon, helium, methane and manmade chlorofluorocarbons or CFCs. The ozone layer is the lower lay...
The Montreal Protocol controls the production and consumption of 96 chemicals that damage the ozone layer (Figure below). Hazardous substances are phased out first by developed nations and one decade later by developing nations. More hazardous substances are phased out more quickly. ...
A new problem emerged, however, when some of the ozone-saving substitutions made for the CFCs were found to be problematic in other ways. Hydrofluorocarbons (HFCs) cause considerably less damage to the ozone layer compared to CFCs because they lack chlorine and bromine, but are powerful...
Explain why the chlorine atoms liberated from CFCs are thought to be a serious threat to the ozone layer. 1) How do CFCs play a role in ozone depletion? Explain and include an equation to demonstrate your answer 2) What are the health ef...
In 1987 the Montreal Protocol was introduced and later signed up to by 120 countries who agreed to half their CFC emissions by the year 2000. We now know that apart from destroying the ozone layer, CFCs contribute significantly to the greenhouse effect. Even though they have been banned, ...

Is there still a hole in the ozone layer? Chaleephoto // Shutterstock Is there still a hole in the ozone layer? There is still a hole in the ozone layer, but it's shrinking, according to NASA. There has been a 20% decrease in the hole thanks to a ban on chlorofluorocarbons (CFCs)...
