    Earth science 21.1 Earth science 21.1 Presentation Transcript

    • Factors that Affect Climate 21.1
    • Tropical Zone
      Region between 23.5˚ north and 23.5˚ south of the equator; the sun’s rays are most intense and the temperatures are always warm.
    • Temperate Zone
      Region located between 23.5˚ and 66.5˚ north and south of the equator; the sun’s rays strike the Earth at a smaller angle in the temperate zone than near the equator.
    • Polar Zone
      The region between 66.5˚ north and south latitudes and the poles; the sun’s rays strike at a very small angle in the polar zone.
    • Key Concept
      As latitude increases, the intensity of solar energy decreases.
    • Key Concept
      The higher the elevation is, the colder the climate.
    • Key Concept
      Topographic features such as mountains play an important role in the amount of precipitation that falls over an area.
    • Key Concept
      Large bodies of water such as lakes and oceans have an important effect on the temperature of an area because the temperature of the water body influences the temperature of the air above it.
    • Key Concept
      Global winds are another factor that influences climate because they distribute heat and moisture around Earth.
    • Key Concept
      Vegetation can affect both temperature and the precipitation patterns in an area.
