There are three major things that the moon and earth go through and that's moon phases, eclipses, and tides.Moon phases are different shapes of the moon you see from earth. Eclipses are when an object in space comes between the sun and a third object, then it casts a shadow on the object. Tides are the rise and fall of ocean water. So that's how moon phases, eclipses, and tides occur.
We have eight phases of the moon we go through. They are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. We have moon phases because the revolution of the moon around the earth. Moon phases don't really don't affect earth. But the moon causes tides.
We have two types of tides and they are spring and heap tides. Tides occur because the differences in how much gravity from the moon and the sun pulls on different parts of earth. Tides are caused by the rise and fall of ocean water. Changes in the positions of Earth, the moon, and the sun affect the heights of tides during a month. So that's how and why tides occur.
There are two types of eclipses the solar and lunar eclipse. A solar eclipse occurs when the moon passes directly between Earth and the sun, blocking sunlight from earth. A lunar eclipse occurs when at a full moon when earth is directly between the moon and the sun. Eclipses occur because on rare occasions, earth, moon, and the sun line up. Eclipses don't really affect earth it only blocks sunlight for a few minutes. So that is Eclipses.
The moon is important in many ways. Like it gives us light and even though we only see on side of the moon. Life without the moon would be really different because without the earth it would be a dark place. Also the earth would rotate way faster. The moon is also important because its our only natural satellite.
