Water
The location of the majority of Earth's freshwater
Glaciers and Ice Caps
The largest source of air pollution
Electricity production
The Geographical factors that control climate are
Latitude and Altitude
Chlorine is added to water to eliminate this type of water pollutant
Bacteria and other microorganisms
Acid rain is caused by excess CO2 and NO2 in the atmosphere emitted by
Burning fossil fuels
The gas most responsible for the greenhouse effect
CO2 Carbon Dioxide
The majority of the freshwater used by humans is used for this industry
Agriculture
Nitric Acid is an example of this kind of air pollutant
Secondary Pollutant
This layer of the atmosphere is affected by seasonal changes, the emission of CFC's, and helps to block UV raditation
Ozone Layer
The majority of ocean pollution comes from
Activities on land
Cities located in valleys that also have large amounts of vehicle traffic are prone to this type of air pollution
Smog
Sea level rise, reduced polar ice, extreme weather, drought, and crop loss are all consequences of
Climate Change
Dams, water pumps, wells, and aqueducts are examples of
Water Management
A pH lower than this number is considered acid rain
5 or lower
Increased cancer rates, sunburns, and plankton die-offs are the result of a decrease of this in the atmosphere
Ozone
A factory dumping pollutants into a river is an example of this type water pollution
Point source pollution
This type of indoor air pollution is most likely to reach unsafe levels in an office building
VOC's
In human history, the largest change in the amount of CO2 in the atmosphere occurred after THIS societal change
Industrial Revolution
Runoff from agriculture and city streets are examples of this type of water pollution
Non-point source pollution
A building which is located in a hot climate that is sealed with a large amount of air conditioning can suffer from this condition
Sick Building Syndrome
The circulation of water in the atmosphere causes belts of the type of environment at 30 degrees of latitude north and south of the equator
Rainforests
VOC's stands for
Volatile Organic Compounds
