  1. Keystone Species - Leaching Crystal Suggs Dr. Simpson APES 17 April 2012

  2. Keystone Species • A species that is far more important in its community than its relative abundance might suggest • APPLICATION • A sea otter is a keystone species

  3. Kinetic Energy • The energy of motion • APPLICATION • Kinetic energy is used when riding a bike up a hill

  4. Kyoto Protocol • An international agreement to reduce global emissions of greenhouse gases from all industrialized countries to 5.2 percent below their 1990 levels by 2012. • APPLICATION • Methane and carbon are greenhouse gases that are mentioned in the Kyoto Protocol.

  5. Lacey Act • A U.S. act that prohibits interstate shipping of an illegally harvested plants and animals • APPLICATION • The Lacey Act protects forests.

  6. Latent Heat Release • The release of energy when water vapor in the atmosphere condenses into liquid water. • APPLICATION • This is important because when the water vapor in the atmosphere condenses, the air will become warmer and this warm air will rise

  7. Law of Conservation of Matter • A law of nature stating that matter cannot be created or destroyed. • APPLICATION • When paper is burned, it may seem to vanish but no atoms are lost; the carbon and hydrogen that make up the paper combine with oxygen in the air to produce carbon dioxide and water vapor.

  8. LD50 • The lethal dose of a chemical that kills 50 percent of the individuals in a dose-response study. • APPLICATION • This helps compare the harmful effects of different chemicals

  9. Leach Field • A component of a septic system, make up of underground pipes laid out below the surface of the ground. • APPLICATION • The pipes in the leach field contain small perforations so the water can slowly seep out and spread.

  10. Leachate • Liquid that contains elevate levels of pollutants as a result of having passed through municipal solid waste (MSW) or contaminated soil. • APPLICATION • Leachate contains toxic chemicals that harm the environment.

  11. Leaching • The transportation of dissolved molecules through the soil via groundwater. • APPLICATION • The leached nitrates eventually settle in the bottom sediments of oceans, lakes, and swamps.
