Across
  1. 2. the orbital motion of a planet or moon around another star or planet
  2. 5. the difference in height between high and low tide
  3. 6. periodic rise and fall of sea levels primarily caused by the gravitational pull of the Moon
  4. 10. a moon phase where more than half but not all of the moon's surface is illuminated appearing as a bulge or hump
  5. 11. when the moon is in between the Earth and the sun dark side we see the moon as a dark circle
  6. 14. the phase of the moon when less than half if illuminated appearing as a thin curved slice of light
  7. 15. tide with a smaller difference between high and low tides occurs on the quarter moons
  8. 16. different forms that the moon take in its appearance from Earth
  9. 17. when the Earth is between the sun and moon and all of the moon's surface facing Earth is illuminated
  10. 18. one complete revolution of the moon around Earth that takes approximately 28-29 days
Down
  1. 1. when the ocean level is at it's lowest point occurs twice per day
  2. 3. when the ocean level is at it's highest point occurring twice per day
  3. 4. more of the illuminated half of the moon can be seen each night, moon seems to grow bigger
  4. 7. tides with the greatest tidal range occurs on a full and new moon
  5. 8. a lunar phase where half of the moon is illuminated occuring roughly halfway between the full moon and new moon phases
  6. 9. when an object spins on it's axis which takes 24 hrs on Earth causing day and night
  7. 12. less of the illuminated side of the moon can be seen each night moon seems to be shrinking
  8. 13. a raised area in the ocean caused by the gravitational pull of the moon
