Which of the following are accurate descriptions of causes of some major environmental problems?

Acid rain is caused by the release of gaseous chemicals that can form acids in the atmosphere. They're often released during the combustion of certain fossil fuels.


B. Ozone depletion is caused by the greenhouse effect, when too much hot air is trapped by the ozone layer.


C. Water pollution is caused both by point source pollutants (such as factories) and non-point sources (such as farms).


D. Deforestation is caused by desertification and erosion problems.


E. Invasive species problems are caused by the introduction of non-native species to an environment where they did not previously exist, and where they do not have any known predators.|||A is true


B is false


C is true


D is false


E is true|||the answer is e i hope|||A, C and E





For B: the greenhouse effect is a result of too much CO2 production. It heats up the atmosphere. Ozone depletion is caused by radical chlorofluorocarbons (CFCs) that have one free electron and easily break up O3.


For D: deforestation leads to desertification and erosion problems, not the other way around.|||A is a correct description of acid rain.


B is incorrect. The greenhouse effect and ozone depletion are not directly linked.


C is correct.


D is back to front: deforestation causes desertification and soil erosion.


E is correct.|||A True


B False (it's caused by chlorine in the upper atmosphere -- it gets there through halocarbons, such as we used to use as aerosol can propellants)


C True


D False (it's the other way around. Desertification is caused by deforestation and erosion).


E True
