  • What is the average temperature when latitudes are lower?
    warmer
  • What is the average temperature when latitudes are higher?
    cooler
  • What is the average temperature when the amount of sunlight is near the equator?
    warmer
  • What is the average temperature when the amount of sunlight is near the poles?
    cooler
  • Different parts of the Earth receive different amounts of solar radiation
  • When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct
  • Solar radiation is concentrated over a smaller surface area, causing warmer temperatures
  • Earth - revolves around the Sun once each year
  • Earth - spins on its axis of rotation once each day
  • axis of rotation - tilted 23.5⁰
  • axis of rotation - pointed toward Polaris, the North Star
  • Tilt of Earth's axis - stays lined up with the North Star
  • Equinox - equal length of day and night
  • Solstice - not equal length of day and night
  • Types of Equinox Phenomenons
    • Spring
    • Autumn
  • Equinox - The length of the day is equal to the lenght of the night
  • Equinox - The Sun's solar energy hits the equator at 90⁰ angle
  • Spring Equinox - March 20 (Northern Hemisphere)
  • Autumn Equinox - September 22 (Northern Hemisphere)
  • Types of Solstice Phenomenons
    • Winter
    • Summer
  • Winter Solstice - December 21 (Northern Hemisphere)
  • Winter Solstice - has the shortest day of the year
  • Summer Solstice - June 21 (Northern Hemisphere)
  • Summer Solstice - has the longest day of the year as a consequence of the earth's tilt
  • Summer Solstice - north pole is tilted towards the sun
  • Summer Solstice - sunlight hits the earth's surface perpendiculary at 23.5⁰ north latitude (Tropic of Cancer)
  • Arctic Circle - 66.5⁰ north latitude
  • Antarctic Cirlce - 66.5⁰ south latitude
  • Winter Solstice - north pole is tilted away from the sun
  • Winter Solstice - sunlight hits the earth's surface perpebdicular at 23.5⁰ south latitude (Tropic of Capricorn)
  • During Winter Solstice, the Arctic Circle experiences 6 months without a sun in the sky
