AP Environmental Science - Friedland and Relyea Chapter 19
Terms in this set (50)
Rising sea levels, increased extraction of fossil fuels, increased contamination, altered biogeochemical cycles, decreased biodiversity, emerging infectious diseases, overharvesting and exploitation of species
Global Climate Change
Increased storm intensity, altered patterns of precipitation and temperature, altered patterns of ocean circulation
Warming of planet's land, air, and water, increased heat waves, decreased cold spells
Greenhouse Warming Potential
Estimates how much a molecule of any compound can contribute to global warming over 100 years compared to a molecule of CO2
Approach that involves taking CO2 out of the atmosphere. Can store in agricultural soils or retired agricultural land.
A trait the improves an individual's fitness
The percentage of incoming sunlight reflected from a surface
Regulations in the United States to improve the average fuel economy of cars and light trucks
Cap and Trade
An approach to controlling CO2 emissions, where a _____ places an upper limit on the amount of pollutant that can be emitted and ______ allows companies to buy and sell allownaces for a given amound of pollution
A family of organic compounds whose properties make them ideal for use in refridgeration and air-conditioning.
the process by which radiation from a planet's atmosphere warms the planet's surface
A gas in Earth's atmosphere that traps heat near the surface
A compound used in place of CFCs as it is less destrucive to ozone layer
Intergovernmental Panel on Climate Change (IPCC)
A scientific body under the UN, dedicated to the task of providing the world with an objective and view on climate change
An international agreement to reduce global emissions of greenhouse gases from all industrialized countries (5.2% by 2012)
A chemical compound which is a group-14 hydride and it the main constitute of natural gas. Burns holes in ozone layer.
Nitrous Oxide (N2O)
A chemical compound, at room temp is a non-flammable gas, and is used as laughing gas.
When carbon is absorbed by soils and is stored there for the long term
The gaseous phase of water. It is produced from evaporation or boiling and is located in our atmospsherse. Most common greenhouse gas.
How much radiation is reflected back into space by the Earth's surfaces?
What is the net-flux of energy in the Sun-Earth Heating System?
Gases in atmosphere that absorb infared radiation
What is the most common greenhouse gas?
What greenhouse gas has the greatest global warming potential?
What are the largest and second largest natural sources of methane?
Wetlands (first), termites (second)
What is the greatest natural contributor to global warming?
What agricultural practices result in greenhouse gases?
irrigation (methane), fertilizers (nitrogen), livestock (methane), manure (CO2 + Methane)
Greatest producers of methane in order of greatest to least
Livestock digestion, landfills, natural gas/petroleum
Greatest producer of nitrous oxides
Greatest producers of carbon dioxide
fossil fuels (for energy), fossil fuels (not for energy)
Who observed that atmospheric CO2 concentrations varied seasonly?
Charles David Keeling
Global tempature rise since 1880
1.4 F or .8 C
Tiny marine organisms whose shells do not decay after death, which allows scientists to gain insight on ancient water tempatures
Deep pockets of ice that are studied due to the air bubbles present inside them that contain the atmospheric conditions of ancient eras
Global tempature rise by 2100
1.8 C to 4.0 C
Limiting greenhouse gas emissions to moderate global climate change
Learning to live with environmental changes and societal consequences brought about by global climate change
Changes in some condition that triggers a response that intensifies the changed condition
What are seasons around the world determined by?
Tilt of earth's axis, revolution around sun, parallelism of Earth's axis
Created by prevailing wind belts that create mass movements of water
Collective effect of changes in earth's movements upon its climate
Three variations of cycles
Eccentricity, acial tilt, precession
Order of layers of atmospheres
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
Gives an estimation of a temperature without the use of a thermometer (Ice cores, tree rings, etc)
Wind that comes from the west
Dry, most persistant winds
The shape of the earth's orbit around the sun. Varies the amount of radiation recieved at the Earth's surface at different seasons
The inclination of the Earth's axis in relation to its plane orbit around the sun. A large tilt result in warmer summers and cooler winters.
Earth's slow wobble as it spins on its axis. Shifts from pointing at Polaris (North Star) to other star Vega
