Who knows where the water goes at high tide and when the tide goes down?

You know, you go to the Qiantang River to have a look!

When the tide recedes, high tides form elsewhere. The tidal phenomenon is a natural phenomenon in coastal areas, which is related to both the sun and the moon, mainly due to the gravitational pull of the moon. The moon revolves around the earth all the time, so when the moon rotates to **, the sea water in the ocean will converge in **.

Tidal phenomena refer to the periodic movement of sea water under the action of celestial gravitational forces, and it is customary to call the vertical rise and fall of the sea surface tide, and the flow of sea water in the horizontal direction is called tidal current.

The distance between the moon and the earth is too far, when the front of the sea water is just facing the moon, under the action of the tidal force generated by the moon on the earth, the force is the largest at this time, so the phenomenon of sea water ** will occur.

At different times of the day, high and low tides occur, and the tide rises in this place, and other places that are further away may be the low tide. Thus a trend was formed.

High tides are a natural phenomenon. The high tide is caused by the gravitational pull of the moon and the sun, and when the tide is high, the sea **, the waves are rolling, and the scenery is spectacular.

The water surface rises periodically due to the gravitational pull of the Moon and the Sun, and the semi-diurnal tide, the full-day tide, and the mixed tidal tide water type.

Let's talk about the tides. Tides are the periodic rise and fall of sea water. Because the day is the morning and the night is the night, the rise and fall of the sea during the day is called"tide", the rise and fall of the sea that occurs at night is called"Tides"。

This phenomenon once made the ancients wonder what caused it. Later, careful people discovered that the tides were delayed for a while every day, and this time was the same as the time when the moon was late every day, so it was thought that the tides and the moon were inevitably related. The relationship between the tides and the moon has been mentioned in the ancient Chinese geographical work "The Classic of Mountains and Seas", and Wang Chong in the Eastern Han Dynasty clearly pointed out in his book "On Balance".

The rise of the waves also rises and falls with the moon"。But it wasn't until Newton discovered the law of gravitation that Laplace mathematically proved that tidal phenomena were indeed caused by the gravitational pull of the sun and moon, mainly the moon. Filial piety.

The water from the high tide and the low tide has returned to the sea. The high tide and low tide are not extra water, but the water in a basin is high here, low there, falls back here, rises again there, and tosses back and forth in this way. So where the tide comes from, it's just a matter of where it returns.

The Earth is a large ball with a diameter of 12,756 kilometers, and this sphere is composed of several levels, namely the atmosphere, hydrosphere, crustal sphere, mantle, and core. The hydrosphere is the rivers, lakes and seas that occupy 71% of the earth's crust, mainly the ocean. The Earth's gravitational pull holds this water firmly attached to the Earth's crust.

However, the earth is rotating and is affected by the gravitational pull of celestial bodies such as the moon and the sun, which dooms these waters to not stay calm, and will inevitably have rough waves and ebb and flow.

In fact, there is a certain pattern of high and low tides, and the earth rotates once a day, so that there are two high tides and two low tides in each sea area. However, since the Moon also revolves around the Earth, this complex mechanism will not be as accurate as twice a day. Therefore, the high tide and low tide of the earth are mainly affected by the gravitational force of the moon, which is a phenomenon of ups and downs, and the water is still the water, which rises and falls in the big basin of the ocean.
