The moons Importance
The moons role
The moon has many different things going on with it. The changing relative positions of the moon, Earth, and the phases of the moon. The different shapes of the moon you see from Earth are called phases. When an object in space comes between the sun and the third object, it casts a shadow on the object, causing an eclipse t take place. Tides are the rise and fall of ocean water that occurs every 12.5 hours or so. Tides are caused mainly by differences in how much gravity from the moon and the sun pulls on different parts of Earth.
There is eight different moon phases. In order they are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent. We have the phases of the moon because the sun is behind our part of the Earth and the Earth casts a shadow on the moon. That's why we see part of the moon sometimes.
Their combined forces produce a tide with the greatest difference between consecutive low and high tides, called a spring tide. The Sun's pull is at right angles to the moons pull. This arrangement produces a neap tide, a tide with the least difference between consecutive low and high. Tides occur because of the moons gravitational pull. They effect Earth because one minute it could be flowing one way but the next it could flow the other way.
There are two types of eclipses: solar and lunar. A solar eclipse occurs when the moon passes directly Earth and the sun, blocking sunlight from the Earth. A lunar eclipse occurs at a full moon when Earth is directly between the moon and the sun. We have phases because the moon passes between the third object causing it to cast a shadow. They don't really effect us on Earth except they are really nice to see.
In conclusion, the moon is important because it moves the tides and it affects the climate. Our lives would be different on Earth. We wouldn't have the same tides all the time.
