REFERENCE



Vocabulary

  • Arctic Circle: the imaginary line that encircles the globe at 66° 33" north latitude. Arctic lands and oceans lie above this circle. “Arctic” comes from the Greek word arktos, meaning bear.
  • Adaptation: a modification of an organism that makes it more suited to live in its environment. Adaptations help an organism survive.
  • Camouflage: coloration that allows an animal or other organism to blend in with the surrounding environment.
  • Carbon Cycle: the movement and exchange of carbon through living organisms, the ocean, the atmosphere, rocks and minerals and other parts of the Earth. Carbon moves from one place to another through various chemical, physical, geological, and biological processes.
  • Carbon Dioxide: CO2 a colorless, odorless, incombustible gas
  • Climate: the average weather conditions in a particular location or region at a particular time of year.
  • Conservation: taking care of our environment by wisely managing its resources.
  • Food Chain: a straight-line diagram that shows “who eats whom” in an ecosystem.
  • Food Web: a diagram that shows the many complex interconnections of "who eats whom" in an ecosystem.
  • Ecosystem: a unit of plants, animals, and nonliving components of an environment that interact.
  • Energy Audit: The process of inspecting a home, workplace, or other building to find ways to use less energy.
  • Greenhouse Gas: natural or manmade gases that trap heat in the atmosphere. Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and fluorinated gases.
  • Ice Floe: a flat expanse of floating ice.
  • Lair: the shelter of some animals; used for birth and protection. May also be called a den.
