Why Does The Moon Affect The Tides? The Gravitational Effect Of Celestial Bodies Is Periodic (Can Generate Electricity)
Although the moon is very far away from the Earth, it has a great influence on the Earth. For example, it affects the ebb and flow of seawater. Why does the moon affect the tide? How does the moon affect the tide? Let the editor lead everyone to understand together!
Why Does The Moon Affect Tides?
The moon has celestial gravitation, which is attractive to the seawater on Earth. Under the gravitational effect of the moon, seawater will have ebb and flow changes, and it is a periodic ebb and flow. Because the daytime is "chao" and the night is "xi", the rise and fall of seawater during the day are called "tide", and the rise and fall at night are called "tide". This ability to attract rising tides is called tidal gravity. The tide is periodic, and the cycle is 24 hours and 48 minutes because the moon circles the earth in 24 hours and 48 minutes. During this cycle, half the time the sea faces the moon, and half the time it faces away from the moon.
How Does The Moon Affect Tides?
The seawater in each part of the earth is different from the moon, so the gravitational force received by different places will be different. Generally, the gravitational force on the seawater closer to the moon will be greater, that is to say, the seawater on the side facing the moon will have a stronger tidal force, and the seawater facing away from the moon will have a smaller tidal force. However, under the action of centrifugal force, even if it is facing away from the moon, the tidal effect will not change. The moon is the dominant force of the tides, but in fact, the sun also has a certain influence on the tides, but this effect is relatively small. Plus, tides are much easier to understand than the three unsolved mysteries of the moon.
Effects Of Tides On Humans
Tides are not only a natural imagination but also related to human life. Take fishing at sea. If you don’t know the law of tides, fishermen don’t know when to go to sea, because going to sea when the tide is high can easily threaten people’s lives and health. In addition, tides play a very important role in military affairs, marine engineering, mariculture, and various marine production activities. Therefore, people have been studying the law of tides, and using tidal drops to generate electricity has brought a lot of benefits to people.
