The tide is the same rise and return of the world, is a hemisphere rising and a hemisphere retreatin

At the center of the Earth, the gravitational pull of the Sun provides the centripetal force for the Earth to move in a circular motion (which is actually an ellipse, but can be understood as such); On the side facing the sun, the gravitational pull of the sea water is greater than that of the sun, and the centripetal force required for its movement is less, so the sea water moves towards the side of the sun and the tide rises; On the side facing away from the sun, the gravitational pull of the sea water is less than that of the sun, and the centripetal force required is greater, so the sea water moves towards the side facing away from the sun, which is also a high tide; Under the action of two high tides, the sea water moves to both ends, and there is less sea water in the middle, and the low tide appears.

The situation is similar on the Moon, and it is not difficult to understand that the Earth moves around the common center of mass of the Earth and the Moon.

When the sun and the moon are in the same straight line, the two effects are superimposed, and there are big ups and downs; When the two are 90 degrees to each other, the role of the two is partially eliminated, and it is a small rise and fall.

The ebb and flow of the tide is not so simple.

Neither, it's two rising tides and the other two falling tides.

Pull and pull "That's right.

However, the tide should rise in two places by the moon (sun) and the moon (sun), and the low tide in places with a difference of 90 degrees from these two places. This involves the "gravitational force", which I came into contact with in my freshman year, and you don't need to remember the specific principle, anyway, it just has to rise and fall twice a day.

It is the place relative to the moon and is tided at the same time to the other side of the moon

Why do the oceans ebb and flow, and how are these tidal phenomena formed?

The rotation of the earth and the rotation of the moon produce gravity, and the sea water will change with the direction of gravity, and the waves are caused by the fluidity of the water and cannot move as a whole, and if there is no rotation, nothing will be there.

Because of the gravitational pull of the moon, tides are created because of the action of tides and wind, and ocean waves are created by the action of tides and wind.

It's not the same. High tides are generated by the gravitational pull between the sun, the moon and the earth, when the sun is facing a certain area of the earth, the sea water in this area is pulled up by gravity to an arch, the sea rises, and the sun leaves the ebb tide: after the sun reaches the earth, the other will also have a high tide, and the high tide caused by the sun is a small tide, one in the morning and one in the evening.

When the sun and moon merge into one line, the sea arches high due to the common gravitational pull, which is called the high tide, which occurs once a month.

Anyone who has ever been to the beach knows that the sea has both high and low tides. At high tide, the sea is **, the waves are rolling, and the scenery is spectacular; At low tide, the water quietly recedes, revealing a beach. Rising and low tides generally occur twice a day.

The rise and fall of the sea water occurs during the day and is called the tide at night, so it is also called the tide. In the ancient books of our country, it is said that "the water of the sea is the tide of the morning and the tide of the sunset".There is a period of time between high tide and low tide when the water level does not rise or fall, which is called flat tide.

How is it formed?

Let's start with the flat tide, which is the general state of the sea. We all know that when the earth rotates, it produces a centrifugal force that throws outward. For example, it's like spinning an open umbrella and the water droplets on the umbrella are about to be thrown out, so the sea will fluctuate in normal times.

Let's talk about the tides. We also know that not only does the rotation of the earth affect the unrest of the sea, but our earth is also affected by the gravitational pull of the moon and the sun. Think about it, when the earth turns to follow the gravitational direction of the sun or moon, is the sea water facing the sun or moon attracted by a gravitational force, and when it is attracted, there is a force that flows outward and wants to rise up and rush out into the air?

However, after all, the gravitational pull of the moon is not strong enough, and the sun is too far away, so they can only lift the sea water, and whoever makes the sea rise cannot let it into space. When the Earth turns to shift the gravitational pull of the Sun and the Moon, it naturally returns to its original state.

Got it? Therefore, the tide usually occurs twice a day. In one day, except for the north and south poles and individual regions, the tides rise and fall twice in each day, each time for 12 hours and 25 minutes, twice a day, a total of 24 hours and 50 minutes, so the time of tide rise and fall is delayed by 50 minutes every day.

It is precisely because of such fluctuations that the seawater can be temporarily replenished by the water that does not rise in other places when the tide rises in one place, thus forming a tidal current and facilitating the exchange of the seawater environment.

Why does the sea rise and fall and what are the main reasons? After reading it, I understand.

The high and low tides of the sea are affected by the moon, and the tide goes whichever way the moon is on the other side of the earth.

The Republic of Kiribati, an island nation located in the middle of the Pacific Ocean, is the only country in the world that straddles the equator and crosses the International Date Line, spanning east and west, connecting north and south, and stepping on four hemispheres at the same time.

Out of the C++ Runtime Library This is a window that I often pop up out of, and if you're too then see below
