AIR POLLUTION A change to the atmosphere that has harmful effects. Substances that cause pollution are called pollutants. (ash, or gases, such as chlorine.) Air pollution can affect the health of humans and other living things. Pollution can even impact the climate of the whole planet.

AIR POLLUTION A change to the a_________ that has harmful e______. Substances that cause pollution are called pollutants. (ash, or gases, such as chlorine.) Air pollution can affect the health of humans and other living things. Pollution can even impact the climate of the whole planet.

AIR POLLUTION

EMISSIONS Solid particles and gases that are released into the air. Sources: motor vehicles such as cars, trucks, and airplanes. Release gases such as carbon monoxide, an invisible toxic (poison) gas.

EMISSIONS Solid p_____ and g____ that are released into the a__. Sources: motor vehicles such as cars, trucks, and airplanes. Release gases such as carbon monoxide, an invisible toxic (poison) gas.

EMISSIONS

OZONE A toxic (poison) form of oxygen. Ozone in the ozone layer is helpful because it blocks ultraviolet rays from the sun. Ozone in the lower atmosphere is not good because it is toxic to humans.

OZONE A t___ (poison) form of o_____. Ozone in the ozone layer is helpful because it blocks ultraviolet rays from the sun. Ozone in the lower atmosphere is not good because it is toxic to humans.

OZONE

GREENHOUSE EFFECT The trapping of heat by certain gases in the atmosphere. In the atmosphere, water vapor, carbon dioxide, and certain other gases act like windows. These gases allow sunlight to reach Earth’s surface, but they prevent the heat from escaping back into space. The trapping of heat near Earth’s surface is called the greenhouse effect. Without the greenhouse effect, Earth would be much colder – about 33°C colder on average.

GREENHOUSE EFFECT The t______ of heat by certain gases in the a_________. In the atmosphere, water vapor, carbon dioxide, and certain other gases act like windows. These gases allow sunlight to reach Earth’s surface, but they prevent the heat from escaping back into space. The trapping of heat near Earth’s surface is called the greenhouse effect. Without the greenhouse effect, Earth would be much colder – about 33°C colder on average.

GREENHOUSE EFFECT

GLOBAL WARMING The theory that increasing carbon dioxide in the atmosphere will raise Earth’s average temperature. Scientists estimate temp could raise 3 to 8 Celsius degrees over the next century. Though this seems small, this could cause Antarctic ice caps to melt  rising sea levels, changing climate patterns. This could change where crops are grown. Might also be more severe storms.

GLOBAL WARMING This could change where crops are grown. Might also be more severe storms.

CARBON FOOTPRINT The total amount of CO2 you create. A big carbon footprint is bad for the planet. When you use fossil fuels, like heating oil to keep your house warm or gasoline for your family car, these things create carbon dioxide, also called CO2. Carbon dioxide is called a greenhouse gas. Many scientists believe that greenhouse gases are making the earth too warm (global warming).

CARBON FOOTPRINT The total a_____ of CO2 you c_____. A big carbon footprint is bad for the planet.

Many scientists believe that greenhouse gases are making the earth too warm (global warming).

CARBON FOOTPRINT

ECOSYSTEM All of the living (biotic), and nonliving (abiotic) things that interact in a particular area. Biotic – animals, fungus, worms, plants, etc. Abiotic – water, sunlight, oxygen, temperature, soil

ECOSYSTEM All of the l____ (biotic), and n______ (abiotic) things that i_______ in a particular area. Biotic – animals, fungus, worms, plants, etc. Abiotic – water, sunlight, oxygen, temperature, soil

ECOSYSTEM

RENEWABLE RESOURCES Resources that are replaced in a relatively short time. Sunlight, wind, trees, etc. Possible to use up renewable resources, for example if people cut down trees faster than they can grow back then they will be used up.

RENEWABLE RESOURCES Resources that are r_______ in a relatively s____ time. Sunlight, wind, trees, etc. Possible to use up renewable resources, for example if people cut down trees faster than they can grow back then they will be used up.

RENEWABLE RESOURCES

NON-RENEWABLE RESOURCES Natural resources that are not replaced as they are used. Coal and oil exist in a limited supply so they are non-renewable. The time necessary to make these resources is much too long to be considered renewable

NON-RENEWABLE RESOURCES Natural r_______ that are not r_______ as they are used. Coal and oil exist in a limited supply so they are non-renewable. The time necessary to make these resources is much too long to be considered renewable
