Stars appears to move from east to west because

  • A.All stars move from east to west
  • B.The earth rotates from west to east
  • C.The earth rotates from east to west
  • D.The background of the stars moves from west to east

Answer: B

Because the earth rotates from west to east.

The apparent motion of the sky is the reflection of that rotation, so the stars rise in the east and set in the west just as the sun does. The whole sky appears to turn once in a sidereal day of 23 hours 56 minutes.
