  1. Earth in Space Mac B., Logan H., Alex S.

  2. Earth, Sun, Seasons • Earth travels around sun in oval-shaped orbit. • It takes 24 hours to complete a rotation. • Rotation= complete turn of earth. • It takes 365 ¼ days to complete a revolution. • Revolution= complete journey around sun. • Earth’s axis is tilted, causing seasons.

  3. Equinoxes and Solstices • Equinox- point where all days and nights are nearly equal in length. • Solstice- point where north (or south) pole is closest to the sun. • Days are the longest in one hemisphere during solstice.

  4. Times • It takes 24 hours to complete a rotation. • Sun rises at different places at different times. • Hard to keep track of times of local sunrises. • This is why we have time zones.
