EARTH'S ROTATION AND
    REVOLUTION
Earth’s Rotation

• Rotation is the
  spinning of the Earth
  on its axis.
• The time for one
  rotation is 24 hours.
• The speed of rotation
   24,855 miles/24 hr
  or 1,038 miles/hr

Earth’s Revolution
• A revolution occurs as the earth moves
  around the sun.
• Time for one revolution = 365 1/4 days
  = 8,766 hours
• The speed of earth’s revolution is
  about 18 miles per second.
Earth’s Revolution
Earth’s Orbit
• The path an object takes as it revolves around
  another object.
Around and Around We Go

• Every second, that you sit in
  this classroom, the Earth's
  orbital motion carries you
  about 18 miles through
  space.
