The moon's role
As the moon moves, the positions of the moon, Earth, and the sun change in relation to each other. The changing relative positions of the moon, Earth, and the sun cause the phases of the moon, eclipses, and tides. The phases of the Moon are caused by the Moon moving in orbit around the Earth, being lit by the Sun from different angles. Eclipses are caused by the Moon in its orbit passing either between the Earth and the or through the Earth's shadow. The tides are caused by the gravitational attraction of the Moon or Sun as the Earth rotates on its axis.

There are eight phases of the Moon, we have phases because the changing relative positions of the Moon, Earth, and Sun. Half the moon is almost always in sunlight. You see the moon from different angles because it orbits Earth. Without the Moon legends would not exist and stories would not be told. Without the Moon phases kids wouldn't have a full moon to blame for behavior.

Tides are caused mainly by differences in how much gravity from the moon and the sun pulls on different parts of Earth. Changes in the position of Earth, the moon, and the sun affect the heights of the tides during a month. When the sun, the moon, and Earth are in line during a new moon its called a spring tide. When the sun, the Earth, and the moon make a right angle its called a neap tide. Tides effect Earth because only 12.5 hours are available to fish in water.

A solar eclipse occurs when the moon passes between Earth and the sun, blocking sunlight from Earth. A lunar eclipse occurs at a full moon when Earth is between the moon and the sun. Whether it is a total or partial eclipse has to do with the penumbra and umbra. During a total eclipse you understand how important the sun is to Earth. Eclipses are important to Earth because they teach us about space.

The moon's role is one of the most important roles in helping Earth survive. Without the moon being present, tidal flow would be barely noticeable and there would be less opportunity for sea creatures to adapt to a land environment. The moon’s gravity has the effect of slowing down the Earth’s rotation. Without the moon days would be shorter and temperatures would be colder. This would have a huge effect on food production.
