  • The spinning around like a top is called rotation. As it spins only one side faces the sun. Day begins when our part of the world turns to face the sun.
  • Night falls when our part of the Earth turns away from the sun. The side facing away from the sun has nighttime.
  • This rotation or spinning of Earth causes day and night. The Earth rotates on its axis. The axis is an imaginary line through its center. It rotates once every 24 hours causing day and night.
  • Every day the Earth travels around the sun. The Earth and the moon travel together in an orbit around the sun once a year.
  • One revolution around the sun equals 365 days. This revolution causes the changing of the seasons. • http://kids.msfc.nasa.gov/earth/seasons/Earth
