Why does the ocean rise and fall? Where did the high tide water come from and where did the low tide water go?

In fact, the earth is a water polo. There are many oceans on the earth, and tides appear every day with certain regularity. Whenever the tide is high, the sea water does not know where it comes from, and people only see the endless ocean. When the tide ebbs, the sea water disappears without a trace, which makes people sigh that nature is so magical. It is this magic that causes many problems.

First, why does the ocean have such a phenomenon?

One thing that human beings have learned is that any object has movement, so there must be changes, and this change will only happen under the action of force. Therefore, the ebb and flow of seawater is also due to its own movement, and its state has changed. In this process, seawater is also subjected to a force, which is gravity.

Newton told us that there is gravity in this universe, and it is everywhere. Anything with mass will produce gravity, and the gravity is directly proportional to the overall mass, that is, inversely proportional to the square of the distance. In the solar system, the mass of the sun is huge, which can be said to account for 99.286% of the mass of the whole solar system, that is to say, the gravity on the earth is great. The distance between the earth and the moon is very close, so the moon has a certain vision of the earth, which has surpassed the sun. Therefore, people can think that tides appear in the earth's oceans because the gravity of the moon absorbs seawater and leaves the earth's surface, thus forming a climax.

Where does the high tide water come from?

In fact, all the oceans on the earth are connected. In this case, water from other ocean areas will come in at high tide. At the same time, some seawater will be lost, so the ebb tide is formed, which means that the high tide and the low tide are an interactive process. When the earth rotates and the moon revolves, the positions of the moon and the earth will change to a certain extent and periodically, so tides will appear regularly in the ocean.

3. Tides have appeared on the back of the earth?

Many people may not understand that tides are caused by the moon, so will there be such a high tide on the side of the earth facing the moon?

The relationship between the moon and the earth is not as people think. The fact is that both the moon and the earth are moving around the same thing, and there is the same center of mass movement between the earth and the moon. In this state of motion, there will be no back-to-back relationship between the two, and the mass of the earth is relatively large, so the * * * centroid position between the earth and the moon is on the earth, within the radius. But the earth will still revolve around this thing. On the side of the earth facing away from the moon, there is centrifugal force competing. Besides its own gravity, the earth also has the gravity of the moon.
