Explanation of tidal wave formation in sea due toe gravitaion force of moon

In summary, the conversation revolved around the explanation of tidal waves in the sea and the role of the moon's gravity. It was clarified that tsunamis are caused by earthquakes, and the term "tidal wave" is a misnomer. The concept of tidal theory and its relation to general relativity was also discussed, with the conclusion that Newtonian mechanics is sufficient for explaining the tides on Earth.

Hello
According to general theory is there any explanation of tidal wave in sea due to gravitation of moon.
How moon warp space time in such a way so that tidal waves are generated in sea?

Tidal waves (aka tsunamis) are caused by earthquakes. The name "tidal wave" is unfortunately a big misnomer. However, if you are interested in tides, the sea level is an equipotential surface, which is affected by the Earth's gravity, the Earth's rotation, and the moon's gravity.

there is not. it's two different meanings/uses of "tidal".


A "tidal wave" is caused by the sudden displacement of a large volume of a body of water, usually an ocean, but can occur in large lakes...This displacement of water is usually attributed to either earthquakes, landslides, volcanic eruptions, or more rarely by meteorites and nuclear tests...http://en.wikipedia.org/wiki/Tsunami

The only way I can think of our moon causing a possible tidal wave (as commonly understood) is if part of it suddenly was broken off, say by a huge meteor strike, and a large chunk passed close by the earth, or if the whole thing left it's natural orbit and passed close by.

As others have already noted, you are confusing tidal waves with tidal theory (better: theory of the tides). If by "tidal wave" you mean a tsunami, then the only things these two phenomena have in common is that they both have "tidal" as a part of their name. The explanation of tsunamis has nothing to do with the tides. The term "tidal wave" is more than a misnomer here, which is why scientists prefer to use the name tsunami rather than tidal wave.

If on the other hand by "tidal wave" you mean phenomena such as tidal bores, even though that truly is a result of the tides, you aren't going to find the answer in general relativity, either. It's not that general relativity can't handle it conceptually; the problem is that the geometry is just too complex for general relativity to handle in practice. General relativity can handle situations such as neutron stars and black holes where the strong gravity fields make the geometry simple. In these situations you have no recourse but to use general relativity because Newtonian gravity is, simply put, wrong.

The Earth, with its lumpy gravity field and its lumpy continents, is a bit too much for general relativity to handle. Besides, there is no reason to go all the way to general relativity to explain the tides. The Earth's gravity field is so weak and the velocities involved are so small that Newtonian mechanics works just fine in explaining the tides.

Thanx to all to clear my doubts...
 

1. What is a tidal wave?

A tidal wave, also known as a tsunami, is a large wave caused by the displacement of a large volume of water in the ocean. This displacement can be caused by various factors, including gravitational forces.

2. How does the moon's gravitational force affect tidal wave formation?

The moon's gravitational force pulls on Earth's oceans, creating a bulge on the side of Earth closest to the moon. This bulge then causes the water level to rise, resulting in a high tide. As the moon moves in its orbit, the bulge also moves, causing the water level to drop and resulting in a low tide. This cycle repeats as the moon's gravitational force continues to act on the oceans.

3. Are all tidal waves caused by the moon's gravitational force?

No, not all tidal waves are caused by the moon's gravitational force. Tidal waves can also be caused by other factors such as earthquakes, volcanic eruptions, and meteor impacts. However, the moon's gravitational force is the primary factor in the formation of regular, predictable tides.

4. Can the moon's gravitational force affect the strength of a tidal wave?

Yes, the moon's gravitational force can affect the strength of a tidal wave. When the moon is in a closer position to Earth, its gravitational force is stronger, resulting in higher and lower tides. This is known as a spring tide. When the moon is in a farther position, the gravitational force is weaker, resulting in lower high tides and higher low tides. This is known as a neap tide.

5. How do scientists study tidal waves caused by the moon's gravitational force?

Scientists study tidal waves caused by the moon's gravitational force by using tide gauges, which measure the water level at different points along the coast. They also use computer models to simulate the effects of the moon's gravitational force on ocean tides. Additionally, satellite data is used to track changes in sea surface height, providing valuable information about tidal patterns and variations.
