Why is the moon broken, and when the moon is broken, is there a time when it is full again?

First of all, the reason why the moon will shine is because it reflects sunlight, but the light travels in a straight line, and the moon is spherical, so not all lunar surfaces can reflect sunlight at the same time, in other words, only the side that reflects sunlight you can see, and you can't see the side that can't reflect it.

It is because the spatial position of the Earth and the Moon is different, so the reflective surface seen is also different.

The leaves are yellow, and there is a time when they are green again.

The sun has set, and there is a time for it to rise again.

The moon is broken, and there is a time when it will be full again;

Whenever the moon rises at night, many people marvel at its beauty and mystical balance pants. But if you look closely, you will find that the moon is not perfectly round every day, but that there are uneven changes in the circle. So, why does the Moon have this change?

Let's take a look at this question.

The principle of the movement of the Moon around the Earth.

To understand the reasons for the moon's changes, we first need to understand the moon's trajectory. The Moon revolves around the Earth and rotates at the same time. Since we can only see one side of the moon, the moon we see is of a different shape.

The size of the Moon does not change, but it reflects different sunlight at different locations, and the relative position between the Earth and the Moon is constantly changing, so there is an uneven circle gap.

Classification of the monthly difference short.

Depending on the shape of the moon, we divide the moon into four states: full, new, first, and second. The full moon is the round moon that we are familiar with, the new moon is a neon sign with only a little arc, the first quarter moon is a semicircular moon, and the lower quarter moon is also a semicircle, just a semicircle on the opposite side. These four states are constantly circulating, and each cycle is called a lunar cycle, which is about a day.

Factors influencing the phases of the moon.

The obvious feature of the change of the moon's round and waning is the different area of the light, and the area of the moon's brightness is mainly determined by two factors: the position of the sun and the orbital position of the moon. Therefore, the relative position of the Earth with the Moon and the Sun is an important factor affecting the change of the phases of the Moon.

Since the Moon's orbit around the Earth is elliptical, it will also appear larger when the Moon is closer to the Earth.

Moon phases and tides.

The waxing and waning of the moon is not just a natural spectacle, it also affects the tidal phenomena on Earth. Due to the Moon's gravitational pull on the Earth, the oceans follow the Moon's motion and produce tides. When the Moon is on opposite sides of the Earth, especially when the Moon is in a straight line with the Sun, the difference in tides is more pronounced.

The tides at this time are called high tides.

Epilogue. The waxing and waning of the moon is the result of a combination of factors, which is not only beautiful, but also reflects the profound laws of nature. By observing the changes in the phases of the moon, people can not only appreciate the beauty of nature, but also better understand how nature works and feel the infinite charm of nature.

Why does the moon change in its roundness? We know that the moon is a moon that orbits the Earth, and it neither heats nor emits light. In the dark space of the universe, the moon is only able to see by reflecting the sun's light.

As the moon moves around the earth, its relative position to the sun and the earth is constantly changing. When it turns between the earth and the sun, the moon is facing the side of the earth and does not shine at all, so we can't see it, and this is the new moon, which is called the new moon. Two or three days after the new moon, the moon slowly turns an angle along its orbit, and it is gradually illuminated by the sun's rays towards the edge of the earth's side, so that we see a crooked crescent moon in the sky.

After that, the moon continued to revolve around the earth, and it shone more and more sunlight on this side of the earth, so that the crooked crescent moon became more and more "fat" day by day. On the seventh or eighth day, half of the moon shines on this side of the earth, and we see half of the moon at night, which is the first quarter moon.

After the first quarter of the moon, the moon gradually turns to the opposite side of the sun, and at this time, it shines more and more on this side of the earth, so that the moon we see is getting rounder day by day. When the moon completely walks to the opposite side of the sun, that is, when the moon shines all the sunlight on this side of the earth, we see a round moon, which is the full moon of Zheng Huai, which is called Wang. After the full moon; On the side of the moon towards the earth, another part of the moon slowly lost its rays of sunlight, so we saw that the moon began to gradually become "thinner" again.

Seven or eight days after the full moon, only half a moon can be seen in the sky, which is the last quarter moon. After the last quarter moon, the moon continues to "thin". After four or five days, there was only a crooked hook left.

After that, the moon slowly becomes completely invisible, and the new moon period begins again. The change in the waxing and waning of the moon is due to the fact that the moon moves around the earth, and it does not emit light and reflects the sun's rays.

Question 1: Why does the moon wax and wane? First of all, the waxing and waning of the moon that we see is called the change of the phases of the moon, also known as the waxing and waning.

Second, why is this happening? Because on the first day of the lunar calendar, the moon orbits exactly halfway between the earth and the sun, and the dark side of the moon is facing the earth, so the moon is not visible from the earth, and it is called the new moon or crescent moon; On the seventh (or eighth) day of the first month, you can see half of the moon, which is dark in the east and bright in the west, which is called the first quarter moon; On the fifteenth (or sixteenth), the moon moves to the far side of the earth, so that the round moon can be seen hanging high in the sky, which is called a full moon or wang; Around the 22nd, the western half of the moon is dark and the eastern half is bright, which is called the last quarter moon. The moon is a lunar month with a cycle from the first quarter of the new moon to the first quarter of the moon, the full moon and the second quarter of the moon.

Therefore, the change in the circle of the moon is determined by the position between the sun, the earth, and the moon. The main reason for the change in the mutual position of these three is that the moon revolves around the earth (the period is about days), and because the earth revolves around the sun (this is a secondary reason), the period of the moon phase change is greater than the sky, about days.

Question 2: Why does the moon have a change in the circle The light on the moon is the reflected light of the sun, because the position of the moon is constantly changing when it revolves around the earth, so the phenomenon of the earth covering the sun's rays will occur, and from the ground, it will be cloudy and sunny within a month.

Question 3: Why does the moon wax and wane? First of all, the waxing and waning of the moon that we see is called the change of the phases of the moon, also known as the waxing and waning.

Second, why is this happening? Because on the first day of the lunar calendar, the moon orbits exactly halfway between the earth and the sun, and the dark side of the moon is facing the earth, so the moon is not visible from the earth, and it is called the new moon or crescent moon; On the seventh (or eighth) day of the first month, you can see half of the moon, which is dark in the east and bright in the west, which is called the first quarter moon; On the fifteenth (or sixteenth), the moon moves to the far side of the earth, so that the round moon can be seen hanging high in the sky, which is called a full moon or wang; Around the 22nd, the western half of the moon is dark and the eastern half is bright, which is called the last quarter moon. The moon is a lunar month with a cycle from the first quarter of the new moon to the first quarter of the moon, the full moon and the second quarter of the moon.

Therefore, the change in the circle of the moon is determined by the position between the sun, the earth, and the moon. The main reason for the change in the mutual position of these three is that the moon revolves around the earth (the period is about days), and because the earth revolves around the sun (this is a secondary reason), the period of the moon phase change is greater than the sky, about days.

Question 4: Why does the moon have a change in the circle The light on the moon is the reflected light of the sun, because the position of the moon is constantly changing when it revolves around the earth, so the phenomenon of the earth covering the sun's rays will occur, and from the ground, it will be cloudy and sunny in a month.

Question 5: Why does the moon have a round gap because the orbits of the sun, the earth, and the moon are different.
