Across
- 2. when tides reaches its highest level
- 7. water on the side of the Earth closest to the Moon is most strongly affected by the Moon’s gravitational pull
- 9. when tides reaches its lowest level
- 12. one quarter of a way through orbit, see half of the moon lighted, causes neap tide
- 13. three quarters of the way through orbit, we see half of the moon lighted, causes neap tide
- 14. phase of the moon as it revolves around the Earth, once every 27.3 days
Down
- 1. force of attraction between all masses in the universe, especially the attraction of the Earth's mass for bodies near its surface
- 3. to move around another object
- 4. occurs at the full and new Moon phases; the Earth, Moon, and Sun are in alignment, pulling the water in the same direction
- 5. see the entire moon lighted, appears bright and round, causes spring tide
- 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
- 8. occurs at the first and third (last) quarter Moon phases; the Sun is at a right angle to the Moon
- 10. the rising and falling of the oceans due to the gravitational attraction of the Moon and Sun; usually occurs twice each day
- 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
