What are the reasons for the vicissitudes of life?
In the long geological history, due to the continuous movement of the earth's crust, it is not uncommon for the sea to become land, the land to become sea, the depressions to rise to mountains, and the mountains to be razed to the ground.

According to legend, on July 7th, 183 1 year, smoke suddenly rose from the sea in the southwest of Sicily in the Mediterranean, and the water column soared into the sky, and the flames soared into the sky. In the deafening roar, an island 60 meters above sea level and about 5 kilometers away from Fiona Fang rises from the sea, steaming like a big steamed bread just baked. The king of England immediately announced to the world that the newly born island was British territory and named it Yulia Island. Who knows that three months later, You Liya Island unexpectedly left without saying goodbye and quietly disappeared into the vast blue waves.

Since the 8th century A.D., the seashore of Holland in western Europe has been deposited at a rate of about 2mm per year. At present, most parts of the Netherlands are below sea level. If there were no strong dams to stop the invasion of seawater, these lowlands would have sunk to the bottom of the sea.

The Himalayas are young and tall mountains in the world. Scientists in China found fossils of trilobites, brachiopods, tongue ferns and other animals and plants living in shallow waters in the Himalayan region, indicating that it was still a Wang Yang as early as 30 million years ago. Later, due to crustal movement, it expanded into land.

When the Himalayas just emerged from the sea and came into this world, it was just an ordinary mountain. Over the past million years, it has risen rapidly at a speed of tens of meters every 10,000 years, and finally surpassed other famous mountains and Gu Shan to obtain the title of "Roof of the World". But it's not enough. It's still 18 every year. The speed of 2 mm continues to rise.

In the 2nd century BC, an ancient temple named Serabis was built in the Gulf of Naples, Italy. This ancient temple has long collapsed, leaving only three marble pillars as high as 12 meters, which still stand on the beach. The surfaces of the upper and lower parts of these three pillars are very smooth and clean, and only one of them, ranging from 3.6 meters to 6. 1 meter, is covered with holes and caves drilled by marine mollusks. What's going on here?

It turned out that when the Serabis Temple was built more than 2,000 years ago, it was still a piece of land. Later, the crust gradually sank, and the lower part of the stone pillar was covered by sediments in seawater and volcanic ash from Vesuvius. In the13rd century, the seawater flooded to more than 6 meters, and marine mollusks attached to the stone pillars. Later, due to the rise of the earth's crust, the sea water gradually receded. Now the small caves on these three pillars have become the symbol of the vicissitudes of Naples Bay.

In the vicissitudes of history, whether there are problems in Daxizhou is still an eternal mystery to be solved by human science.

Plato (427-347 BC), a famous philosopher and mathematician in ancient Greece, recorded a legend in detail in his two dialogues: About 9,000 years ago, there was a very large island in the Atlantic Ocean called Daxizhou. Here, the climate is mild, the forest is dense, the flowers are exotic, the scenery is colorful and rich in gold. There is a powerful country with a fairly developed culture on the island, which is ruled by Chief 10 and meets once every 10 years. There is a magnificent palace in the capital, which is built on the top of the mountain. This country not only rules the nearby islands, but also rules some places on the other side of the mainland. With its strong economic and military strength, it once launched a war of aggression against Europe and Africa, and its sphere of influence reached Egypt in North Africa and parts of Europe. Later, due to a strong earthquake, Oceania sank to the bottom of the Atlantic Ocean in just one day and one night.

Whether it is the rise of Himalaya or the unsolved mystery of Dayu, it shows that the sea will become a mulberry field and mulberry field will become an objective law of the sea. The reason why the vicissitudes of life have changed greatly is mainly because of the continuous movement of the earth's crust. Due to the movement of the earth's crust, the land in some areas sinks or rises, causing changes in the surrounding sea surface, causing the sea surface in some areas to rise or retreat, causing the land to rise and fall. Time tells us that the crustal movement is slow and the geological history is long. The vicissitudes of life have never stopped since the birth of the earth, still exist today, and will certainly not end in the future.
