Acid Precipitation
precipitation, such as rain, sleet, or snow, that contains a high concentration of acids (Sulfur and Nitrogen), often because of the pollution of the atmosphere
Acids
Sulfur Dioxides Nitrogen Oxides
Climate

Climate Change
long-term significant change in the weather patterns of an area
Global Warming Effects
Rise in sea levels and average temperatures
Greenhouse Effect
natural situation in which heat is retained in Earth's atmosphere by carbon dioxide, methane, water vapor, and other gases
pH

Primary Pollutants
pollutants that are put directly into the air by human or natural activity.
Kyoto Protocol
controlling global warming by setting greenhouse gas emissions targets for developed countries (no teeth)
Montreal Protocol
meeting in 1987 where a group of nations met in Canada and agreed to take steps to fight against Ozone Depletion-CFC's banned (success)
Ozone Layer
a layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun
Rain Shadow
the area on the dry, sheltered side of a mountain, which receives little rainfall
Secondary Pollutants
pollutants that form from chemical reactions that occur when primary pollutants come in contact with other primary pollutants or with naturally occuring substances, such as water vapor.
