Summarize the main content of the last natural paragraph of Tsunami in one sentence

The central sentence of the last sentence of the text is the first sentence, and the main content of the text is this sentence: The Pacific region has the highest number of tsunamis in the world, accounting for 80 per cent.

The details are as follows: 1. The original paragraph is as follows:

The Pacific region has the highest number of tsunamis in the world, accounting for 80 per cent. The waters of the Northwest Pacific Ocean are the most concentrated areas of tsunami. Globally, tsunamis occur mainly along the Pacific coast of Japan, in the western, southwestern and southern Pacific Ocean, and along the coasts of the Hawaiian and Aleutian Islands.

Although China is a multi-** country, tsunamis are rare. In the past two years, there have been very few ** tsunamis recorded accurately along the coast of China.

2. Explain the concept of the central sentence:

According to the interpretation of "Modern Chinese", "center" means "the main part of things". In the old language teaching, there has always been a term - the central idea, which consists of two parts - the main content of the text and the emotions expressed by the author in the text (i.e., the purpose of writing). We can understand it this way:

The "center" is the first half of the "central idea", and the sentence that can summarize the main content of the article is the "central sentence".

2) Narrative texts. To read such texts, it is necessary to grasp the time, place, people, and causes, processes, and results of events.

FYI)

1. From the point of view of content, this paper introduces the tsunami, which is the object of explanation, from four aspects: its - and disaster reduction research.

2. The cause of the tsunami is: ——

A: Tsunamis are caused by ** on the seabed, volcanic eruptions, and celestial impacts. (Short answer).

1) Tsunamis may occur on the seabed, volcanic eruptions, cosmic celestial impacts, etc.

2) The seabed** is the main cause of tsunamis. When the seabed is strong, the seabed stratum is fractured, and some strata rise or sink suddenly, causing the entire water layer from the seabed to the sea surface to "shake" violently.

3. If you are a tourist on the coast, after reading this article, what kind of phenomena can you judge that a tsunami may be about to occur, and make a decision to flee the coast quickly?

A: If you see an unusually high or low tide on the shore and hear a roar of low frequency that is different from the usual wave sound, you should quickly flee the shore. (Short answer).

1) Some ** cause a large-scale sharp decline in the crust of the seabed, the seawater first swells to the space of sudden staggered subsidence, and a large-scale accumulation of seawater appears above it, when the inrush of seawater meets resistance on the seabed, it turns back to the sea surface to produce compression waves, forming long waves and spreading around. Tsunamis formed by the movement of the seafloor crust in this descending type first manifest as an abnormal low tide phenomenon on the coast. Some ** cause a large-scale sharp rise of the earth's crust on the seafloor, and the seawater also rises with the uplift area, and a large-scale seawater accumulation occurs above the uplift area, and then the seawater spreads to the surrounding areas, forming turbulent waves.

On the coast, the first manifestation is an abnormal high tide.

2) The raging waves set off during the tsunami can reach a height of more than 10 meters to dozens of meters, forming a "wall of water", and the speed can reach hundreds of kilometers per hour, forming an amazing spectacle of "the four seas churning clouds and water fury". In addition, tsunamis have a large wavelength and can travel thousands of kilometers with little energy loss. Before the tsunami arrives, it emits a roar of very low frequency that is completely different from the usual wave sound.

4. This paper uses a variety of illustration methods, try to give an example, and explain its function.

Answer: Example: "A tsunami is a powerful destructive wave" uses the explanatory method of interpretation, which gives the reader a clearer and more complete understanding of "tsunami".

Summary. Hello, the first paragraph of the mysterious tsunami writes about tsunamis, which are usually caused by the seabed **. The raging waves set off by the tsunami are extremely destructive hydrometeorological disasters, and it is difficult for people to escape from its clutches if they do not avoid them in time.

Hello, I have seen your question and am sorting out the answer, please wait a while

Hello, the first paragraph of the mysterious tsunami writes about tsunamis, which are usually caused by the seabed **. The turbulent waves set off by the tsunami are extremely destructive hydrometeorological disasters, and if they do not collapse and take shelter in time, it will be difficult for people to escape under its claws.

Write in more detail about the fact that the tsunami devastated it.

In addition, most of the tsunamis come from the bottom of the sea, and the destructive ** tsunami is slowing down, and the depth of its epicenter is more than 20 kilometers, and the Richter earthquake is above the level of seepage. In modern times, underwater nuclear tests often cause a man-made tsunami.

2 Big, round, fragrant and sweet.

3 In an instant, the waters turned inky black, and quickly receded from the shore. There was a roar of the sky falling apart, and the sea water came overwhelmingly with the momentum of overwhelming the mountains and the sea.

4 I want to lure the villagers to the mountains and avoid the tsunami.

Mysterious TsunamiOn December 26, 2004, a Richter scale** struck off the coast off the northern island of Sumatra, Indonesia. ** Triggered a tsunami that killed more than 250,000 people in Indonesia, Sri Lanka, India, Thailand, Malaysia and other countries. What exactly is a tsunami?

A tsunami is a wave of ocean that is highly destructive. Tsunamis may occur at the bottom of the sea, volcanic eruptions, and cosmic celestial body impacts. The seabed** is the main cause of tsunamis.

The seabed** is the main cause of tsunamis.

There are three types of causes of tsunamis:

One is caused by meteorological changes, such as an abnormal rise in the sea level caused by the passage of a strong depression, which is called "storm surge";

Second, it is caused by geological changes, such as **, volcanoes, submarine faults, and landslides, which are called "tsunamis", just like the tsunami that occurred in the Indian Ocean;

Third, it is caused by nuclear **, artificial**, etc. After World War II, the United States conducted a nuclear test on Bikini Island in the North Pacific Ocean that lasted for many years, which once induced sea metaphors.

It talks about the types and causes of tsunamis.

Descending tsunami: some tectonic ** causes a large area of sharp decline in the submarine crust, the sea water first swells to the space of sudden dislocation and subsidence, and there is a large-scale accumulation of seawater above it, when the inrushing seawater encounters resistance on the seabed, it turns back to the sea surface to produce compression waves, forming long waves and large waves, and propagating and spreading around, the tsunami formed by the movement of the submarine crust of this descending type is first manifested as an abnormal low tide phenomenon on the coast. The 1960 Chile** tsunami was of this type.

Uplift "Tsunami": Some tectonic structures ** cause a large-scale sharp rise of the seafloor crust, and the seawater also rises with the uplift area, and there is a large-scale accumulation of seawater above the uplift area, under the action of gravity, the seawater must maintain an equipotential surface to achieve relative equilibrium, so the seawater spreads from the wave source area to the surroundings, forming a turbulent wave. The tsunami waves formed by the movement of the seafloor crust in this uplifted type first appear as an abnormal high tide phenomenon on the coast.

On May 26, 1983, the tsunami caused by the Sea of Central Japan 7 7** was of this type.
