KEYSTONE SPECIES - LEACHINGCrystal SuggsDr. SimpsonAPES17 April 2012
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
KINETIC ENERGY The energy of motion APPLICATION
Kinetic energy is used when riding a bike up a hill
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.
LACEY ACT A U.S. act that prohibits interstate shipping of
an illegally harvested plants and animals APPLICATION
The Lacey Act protects forests.
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
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.
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
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.
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.
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.
