Earth’s tilt and revolution cause changes in seasons Tropics of Cancer and Capricorn mark points furthest north and south that the sun’s rays shine directly overhead at noon This day is called the solstice (summer and winter) Equinox: days and nights all over the world are equal in length (spring and fall) Weather: condition of atmosphere at a particular location and time Climate: conditions over a long period of time (Georgia has a temperate climate) Precipitation Cloud (water vapor) cover Landforms and bodies of water (water heats and cools slowly, land quickly) Elevation (higher elevations have thinner air and cannot hold moisture) Air movement Wind: distributes the sun’s heat through convection (transfer of heat by upward motion of air) Ocean currents: warm currents flow away from the equator and toward the poles, cold flows back to equator, they also move heat throughout the globe Latitudes: low(tropical) always hot, middle (varies), high (polar) always cold Elevation: temperature drops about 3.5 degrees F for every 1000 feet Topography: cool winds on windward side, dry and warmer on leeward side El Nino: natural change in climate off west coast of South America, easterly winds change direction, warm water and heavy rains push toward Americas, drought in Asia and Australia La Nina: warm water blows toward Pacific Rim, precipitation in India, dryness in Americas Can you guess which one we are currently experiencing? Ecosystem: community of plants and animals Biome: specific region Forests: broadleaf (deciduous) trees/rain forest, needle leaf (coniferous) cone bearing/pine Grasslands: flat, few trees, tropical savanna, Northern Hemisphere has steppe/prairie Desert and tundra: extreme dry or cold climates
