The Moon's Role
Because of our moon we have tides, phases, and eclipses. There are eight phases of the moon. We also have two different types of eclipses, lunar and solar. With tides there is a high tide and a low tide. We have these things because of our moon.
There are 8 different moon phases. When the moon is in the waxing it appears to be shrinking. When the moon is in the waning it appears to be becoming larger. A full moon is when all of the moon is seen. A new moon is when none or just a little of the moon is seen. First and third quarter is when half of the moon is seen. Those are the moon phases.
There are two different types of tides. Tides happen because of the changes of positions of Earth, the moon, and the sun. The positions affect the height of the tides. A spring tide occurs when combined forces produce a tide with the difference between consecutive low and high tides. A heap tide occurs when the sun's pull is at right angles to the moons pull, causing a tide with the least difference between consecutive low and high tides.
There are two different types of eclipses. A solar and a lunar eclipse. Lunar eclipses occurs at a full moon when Earth is directly between the moon and the sun. Solar eclipses occur when the moon passes directly between Earth and the sun, blocking sunlight from Earth. Those are eclipses of the moon.
Without our moon Earth and the people inhabiting it would loose so much. The moon is the reason for tides, eclipses, and it's phases. Our tides would be constant, causing people to loose their jobs. It was the moon that helped us figure out the time and months! Gravity would be messed up. Earth without it's moon would be a complete and utter mess.
