The chandong river, which is known for its location in zhejiang province, is mentioned by all as well, and is well known for being visited by tourists every year. It's even more poetic: "the twilight of the twilight of the twilight." it's as if there's power in the usual river." it is clear how powerful and alarming the tide is。
How did the chai tong river tide come about? Is it the same thing as the rising tide? Let's talk to you today。
Zero-one, gravity isn't the same as tidal power
Seeing that gravity is being used to calculate the impact of the sun and the moon on gravity, it seems unreasonable to think that the impact of the moon on the earth is only 1/270。
Because gravity is not the same as tidal force. With regard to tides, another thing should be used, called tidal force, which requires another calculation: the tidal force that works on the celestial body, which is proportional to the diameter of the object, and the cube that produces gravity at the distance of another object。
The tidal force acting on an astroNodal body, such as the earth, is directly proportioTo the diameter of that astroNominal body and extremely proportioNo, i don't, i don'tYou know, as the moon or the sun.
Therefore, in the calculation, a cube is selected instead of a square. This is precisely the opposite of what the sun does to the moon, which is about 2. 2 times as powerful as the tide。
02, how the tide was formed
The tide is formed mainly because of the sun and moon gravity. Many times, we feel that the tide seems to be a wave, so we think that it is caused by the wind, but otherwise, people who live by the sea must be familiar with the regular rise and fall of the sea, regardless of the size of the wind, which suggests that the tide has other effects. And that influence is the object。
When we believe in physics, we all understand the equation of gravity, but it's hard for us to feel the gravitational differences that objects give us, for example, between day and night, and we don't feel gravitational changes. But when this scale is scaled up to the astronomical scale, gravity is obvious. The two main planets, the sun and the moon, have created enormous gravity for our planet, which is a tidal phenomenon of the oceans。
Of course, this tidal phenomenon is already huge, and if it gets bigger, you can see interstellar passage, where the tide is so powerful that it can destroy everything。
03, why is the chai tong river so spectacular
If it says that the tide is universal, then why is it so good? The answer is always good。
First of all, the times of the golden tong river tide are almost identical each year. Why? Because at this point in time, the sun, the earth and the moon are roughly on the same line, the resulting tidal forces are enormous and naturally large。
Then there's the land, the unique terrain of the chandong river, and this tide's performance is exacerbated
The shrinking structure of the chandong river, which is called horny and has a constant volume of water, has become increasingly violent as the river narrows。
And according to previous predictions, we can also see that during this period, the tide of the chandong river was the strongest
