| solar eclipse | When the NEW moon comes directly between the sun and the Earth. (Sun > NEW moon > Earth) |
| What you see when the moon is in the full moon phase | The moon appears fully lit by the sun's reflected light. |
| What is the order of the Earth, sun, and moon during a solar eclipse? | Sun > NEW moon > Earth |
| What you see when the moon is in the new moon phase | You aren't able to see the moon |

| How does the moon affect high tides? | The moon's gravitational pull causes the tides. |
| How many high tides are there each day? | 2 high tides |
| During what moon phases do we experience the highest of the high tides? What is the reason for this? | During the full or new moon because the sun and moon act together to create a larger tide. |
| During what moon phases do we experience the lowest of the low tides? What is the reason for this? | During quarter moons when the sun, moon, and Earth are at right angles to each other |
| Neap tide (low tide) | When the sun, moon, and Earth form a right angle during the 1st and 3rd quarter moons. |
| Spring tide (high tide) | When the sun, moon, and Earth are aligned during a full or new moon. |
