Across
  1. 2. when tides reaches its highest level
  2. 7. water on the side of the Earth closest to the Moon is most strongly affected by the Moon’s gravitational pull
  3. 9. when tides reaches its lowest level
  4. 12. one quarter of a way through orbit, see half of the moon lighted, causes neap tide
  5. 13. three quarters of the way through orbit, we see half of the moon lighted, causes neap tide
  6. 14. phase of the moon as it revolves around the Earth, once every 27.3 days
Down
  1. 1. force of attraction between all masses in the universe, especially the attraction of the Earth's mass for bodies near its surface
  2. 3. to move around another object
  3. 4. occurs at the full and new Moon phases; the Earth, Moon, and Sun are in alignment, pulling the water in the same direction
  4. 5. see the entire moon lighted, appears bright and round, causes spring tide
  5. 6. moon phases when its between the Earth and the Sun, moon cannot be seen due to the lighted half facing the Sun & its dark side facing Earth, causes spring tide
  6. 8. occurs at the first and third (last) quarter Moon phases; the Sun is at a right angle to the Moon
  7. 10. the rising and falling of the oceans due to the gravitational attraction of the Moon and Sun; usually occurs twice each day
  8. 11. periods of the year with particular weather and temperature caused by the tilt of Earth on its axis and its revolution around the Sun
