The ROTATION of the Earth causes day and night.
4
  • Earth's Rotation
  • around its Axis
  • Earth rotates around its own axis
  • Through 360 once every 24
  • hours. This is the cause of day
  • and night.
  • The Earth's polar axis tilts at an
  • angle of 23,5 with its orbital
  • plane around the sun. This
  • inclination (tilt) is responsible for
  • the climate changes and the
  • seasons experienced on
  • Earth.   

5
  • As the Earth revolves around the Sun, the part of
    Earth
  • that points toward the Sun changes. The part of
    the
  • Earth pointing toward the Sun is having summer
    and the
  • part of the Earth pointing away from the Sun is
  • experiencing winter.

  • The equator always
  • receives DIRECT
  • sunlight and is
  • therefore always
  • hotter. The poles
  • always receive
  • ANGLED (indirect)
  • sunlight and are
  • always colder.

8
  • The Earth is divided
  • into 3 major climate
  • zones. These zones
  • are divided based on
  • temperature and
  • precipitation.

9
Factors that Influence Climate
  • 1.Latitude how far an area is away from the
    equator. (The further north or south of the
    equator you are, the colder the climate will be.)

10
  • Tilt of the Earth Earth is tilted at a 23.5
    degree angle. Areas around the equator receive
    direct sunlight year round.
  • 3. Prevailing Winds winds from different areas
    carry different temperature air.

11
  • Large Bodies of
  • Water water holds
  • heat better than land
  • and the prevailing
  • winds carry the
  • heat/cold to ot
  • her
  • areas.
  • 5. Ocean Currents currents carry warm or cold
    air to other parts of the world.

12
  • Mountains affect the temperature and amount of
    precipitation of an area.
