APES Global Change
Terms in this set (20)
The phenomenon causing global warming occurs primarily in this region of the atmosphere. ____
The beneficial ozone layer is in this region of the atmosphere. _____
Most oxygen is found in this layer of the atmosphere. _____
a form of oxygen that has three oxygen atoms in each molecule instead of two. protects us from dangerous ultraviolet radiation from the sun
1.) UV rays break apart an oxygen molecule creating two Oxygen Atoms (O2)
2.) The 2 O atoms undergo a binding collision w/ another O= O3
absorbs UV radiation
caused by CFCs, methyl chloroform, carbon tetrachloride, halon, methyl bromide all of which attack stratospheric ozone.
group of chemical compounds used in refrigerators, air conditioners, foam packaging, and aerosol sprays that may enter the atmosphere and destroy ozone
effects of ozone depletion
increased UV, skin cancer, cataracts, and decreased plant growth.
causes of ozone depletion
CFC's (chlorofluorocarbons) and HCFC's (hydrochlorofluorocarbons)
Examples are carbon dioxide, chlorofluorocarbons, ozone, methane, water vapor, and nitrous oxide.
natural situation in which heat is retained in Earth's atmosphere by carbon dioxide, methane, water vapor, and other gases
an intensification of the Greenhouse Effect due to the increased presence of heat-trapping gases in the atmosphere.
impacts of global warming
Ecological Systems (biodiversity), Sea level rise (erosion/ salinity), troubles with water resources (floods/ droughts), length of growing season changes, heat waves, more ozone problems, health affects
A species moved by humans, either intentionally or accidentally, from its native location to a new geographic region; also called non-native or exotic species., outcompetes for resources, competitive exclusion principle. Honeysuckle, Kudzu, Rabbits in Australia. Second greatest threat to biodiversity
a species whose numbers are so small that the species is at risk of extinction
a species that could become endangered in the near future
any of several organic compounds composed of hydrogen, fluorine, and carbon. HFCs are produced synthetically and are used primarily as refrigerants.
change that occurs in the chemical, biological, and physical properties of the planet (both natural and anthropogenic)
global climate change
changes in the Earth's climate (average weather in an area over a period of years or decades)
