The benefits brought by the moon to people

The gravity of the moon on the earth is the cause of ocean tides. When the sea water moves, it will have a slight friction with the rotating earth. These frictions slightly slow down the rotation of the earth. If there were no moon, the sea water might be evenly distributed all over the planet, resulting in less friction.

This means that the earth will no longer slow down, which means that the length of a day will change. Without the moon, a day will only last for six to twelve hours, instead of twenty-four hours now. If the days were so short, we would spend thousands more days in each natural year instead of 365 days.

The moon has an influence on the earth's horizontal plane and water movement, and the ocean tides will weaken. The high tide occurs where the ocean protrudes to the moon, or where the moon pulls the seawater to itself. On the other side of the earth, the ocean bulges away from the moon, forming another climax. Low tide appears on both sides of the uplift. You know, the earth rotates, so when it rotates, the high tide becomes the low tide.

If there were no moon, the current tide would be reduced to 1/3. The sea level will be lower at high tide and lower at low tide. This is because the sun will replace the moon to influence the tides, and the gravity of the sun acting on the earth is relatively small, which leads to the reduction of the tides.
