- 3. Tides with the greatest tidal range, occurs on a full and new moon.
- 4. More of the illuminated (lighted by the sun) half of the moon can be seen each night, it seems to grow bigger.
- 9. When the Earth is between the sun and moon and all of the moon’s surface facing Earth is illuminated.
- 10. A moon phase where more than half, but not all, of the moon's surface is illuminated, appearing as a bulge or hump.

- 12. When the ocean level is at it's highest point, occurs twice per day.
- 13. Periodic rise and fall of sea levels, primarily caused by the gravitational pull of the Moon.
- 14. When an object spins on it's axis, gives Earth day and night which takes 24 hours.
- 16. A lunar phase where half of the Moon's visible surface is illuminated, occurring roughly halfway between the new moon and full moon phases.
Down
- 1. a raised area in the ocean caused by the gravitational pull of the moon
- 2. The orbital motion of a planet or moon around another star or planet.
- 4. Less of the illuminated side of the moon can be seen each night, seems to be shrinking.
- 5. The moon is between the Earth & the sun, dark side faces Earth, we see the moon as a dark circle.
- 6. The phase of the moon when less than half is visible, appearing as a thin, curved slice of light.
- 7. Different forms that the moon takes in its appearance from earth.
- 8. Tides with a smaller difference between high and low tides, occurs on the quarter moons.
- 13. The difference in height between high and low tides.
- 15. One complete revolution of the moon around Earth that take approximately 28-29 days.
