The Moon's Importance
The Moon's Role
The moon effects Earth in many different ways. From phases and tides to rare eclipses. Phases are the appearances of the moon. Eclipses are caused by shadows on or caused by the moon. Tides are what causes the ocean levels change throughout the day. Without the moon life on earth would not be the same.
Phases are proof that the moon rotates around Earth. Each night the moon appears to be different. The moon takes about 29.5 days to orbit Earth. This is why each month is about thirty days Each phase has a name depending on how much of the moon is seen and what side you can see. There are two terms you need to know to understand phases. Waxing means that the moon appears to be shrinking. Waning means the moon appears to be shrinking. Waxing appears on the right and waning appears on the left. When the moon cannot be seen it is called a new moon. When less than half the moon can be seen it is a crescent. A quarter when half is seen. First is waxing and Third is waning. When more than half is seen it is a gibbous. When all is seen it is called a full moon. Without phases we wouldn't be able to tell that the moon moves.
Tides are the rising and falling of the ocean level. Tides are caused by the Moon's gravitation pull. There are two types of tides: spring and neap. Spring is more drastic than neap. Spring happens on the First and third quarter. Neap happens on new and full moons. Without the moon a person who lives off the ocean life might be different. For example, a boater's schedule is based off tides.
There are two types of eclipses: lunar and solar. One type of eclipse is the lunar eclipse. When these happen the moon seems to turn a sort of reddish orange color. These happen when the Earth is directly in between the sun and the moon. Lunar Eclipses only happen on a full moon. The other type of eclipse is a solar eclipse. When this happens the moon covers up the sun to make it seem as though it is night. This happens when the moon is directly in between the sun and the Earth. These only happen on new moons. An eclipse has two parts; the umbra and the penumbra. The umbra is much more darker than the penumbra.
Without the moon life would be very different. Some peoples lives revolve around the moon. For example, some people in third world countries us the moon as their light since they cannot afford electricity. Other people that use the moon are surfers. The moon's gravity helps create waves. Another thing is that there would be no eclipses since there is nothing to create a shadow or have shadowed on. The third thing is humans may have already been to Mars since there is nothing closer. Of course there would be no phases since there is no moon.
