1. Easter Island Stone Mystery (one of the seven unsolved mysteries in the world)

Easter Island is famous for its stone statues. There are more than 1000 giant stone statues and the remains of Dashicheng on the island. 19 14 and 1934 were investigated, and 1955 was engaged in excavation work. The results show that there are three cultural periods on the island. Early huge stone walls can be used to observe the sunrise direction of a year. Small and medium-sized stone statues are made of dark basalt, tuff and volcanic slag, and the isotopic carbon determination time is about 1680 BC. The middle stage is characterized by long ears and legless busts on the stone platform. The stone statue is 3-6 meters high. The tallest statue is 9.8 meters long and weighs about 82 tons. A stone statue more than 6 meters high.

There are nearly a thousand huge stone statues on Easter Island. They lie on the barren hillside or seaside in Shan Ye. Among them, dozens of statues stand alone or in groups on artificial platforms by the sea, facing the sea and looking up from afar. These legless busts are lifelike, with high nose, deep eye sockets, long ears, upturned mouth and hands on the stomach. Stone statues are generally 5- 10 meters high and weigh dozens of tons. The tallest statue is 22 meters high and weighs more than 300 tons. Some stone statues have red stone caps on their heads, weighing 10 tons. These stone statues, which are called "Moai" by the locals, are carved from dark basalt and tuff, and some of them are inlaid with shells to make their eyes shine.

What is puzzling is who carved these stone statues on the island? What does it symbolize? How did people transport them from the quarry to the seaside dozens of kilometers away? Some people say that this is the masterpiece of aliens.

■ Rotating Island No.2

It is said that a Greek cargo ship, during a long voyage, found a rotating monster on the sea 1000 meters away from the ship. At first, they thought they had met super marine animals, which scared the captain and sailors to do nothing. Later, when I got closer, I saw clearly that it was an island. According to calculations, the island rotates very fast, with the fastest rotation every minute and the slowest rotation every 12 minutes. How can an island in this ocean spin? Some researchers have visited many times, but so far they have not reached a satisfactory result.

■ Island No.3 that can be divided and combined.

In the vast Pacific Ocean, there is a very strange island. Sometimes the island will separate itself into two islands, and sometimes it will automatically synthesize an island. The clutch time is irregular, ranging from 1 to 2 days to 3 to 4 days. When separated, the two parts are about 4 meters apart, and when merged, they become a whole.

■ No.4 Bayer Island

On the east coast of Canada, there is a barren island called Hibel Island. On the island, grass doesn't grow, birds don't rest, there are no plants, only hard blue stones. Strangely, whenever a seagoing ship approaches the island, the needle on the ship will suddenly fail, and the whole ship will be attracted to the island as if possessed, causing the ship to hit the rocks and sink, as if a god of death were manipulating it. Many navigators "fear the island" and call it "the island of death".

■ No.5 Crying Island

In the Pacific Ocean, there is a desert island only a few kilometers away from Fiona Fang. No matter day or night, it will make a crying sound. Sometimes it sounds like people are wailing, sometimes it sounds like birds and animals are wailing, which is very sad. Ships passing by here were surprised, panicked and even shed tears. No one can explain why the island cries day and night.

■ Island 6 that will "travel"

In the Atlantic Ocean southeast of Canada, there is an island called Sable. This island is very strange. It can move, and it moves very fast, as if it had feet walking. Whenever there is a strong wind in the ocean, it will be blown away from its original place like a sailboat and make a "trip" at sea. The island is 40km long from east to west and1.6km wide from north to south, with an area of about 80km2, which is crescent-shaped. Because the sea breeze blows day and night, in the past 200 years, the island has "traveled" 20 kilometers eastward, with an average annual movement of 100 meters. Sabl Island is also the most dangerous "sunken island" in the world. More than 500 ships sank here, and more than 5,000 people were killed. Therefore, this sea area is called "Atlantic graveyard", "ship-wrecked butcher's knife" and "ghost island with magic shadow".

In the Antarctic waters of the southern hemisphere, there is also an island that can "travel", called Bouvet Island. It can walk automatically and is not affected by wind and waves. 1793, the French explorer Bouvier first discovered this island and determined its exact location. Who knows, after 100 years, when the Norwegian expedition landed on the island, the island with an area of 58 square kilometers moved 2.5 kilometers to the west. What prompted it to travel away from home is still a mystery.

■ Ghost Island No.7

1831July 10, an island suddenly appeared in the western waters of Tonga in the South Pacific due to the eruption of submarine volcano. With the continuous eruption of the volcano, an island with a height of more than 60 meters and a distance of nearly 5 kilometers has gradually formed in Fiona Fang. However, when people are still talking about it and have a plan, it disappears like a ghost on the ocean. A few years later, when people forgot all about it, it appeared from the sea like a ghost. According to historical records, 1890 was 49 meters above sea level, and 1898 sank 7 meters underwater. 1967,65438+February, it surfaced again, but 1968, it disappeared without a trace. In this way, the island appeared many times, disappeared many times and changed a lot. 1June, 979, the island grew out of the sea again. According to scientists' prediction, if the volcano stops erupting in the future, the island may still sink and disappear. Because this island appears and disappears at sea like a ghost, people call it "Ghost Island".

On the sea 20 kilometers northwest of Miyakojima, there is also a ghost island with an area of 150 square kilometers. Unfortunately, only on the day when the tide changes the most in a year do you want to emerge from the sea, and only for three hours, and you can't see it at other times.

■ No.8 Dust Island

Among more than 200,000 islands, the island mainly composed of dust is Hawaii Island in the middle of the Pacific Ocean. This inference is based on Williams of the University of Maryland? Some scientists, led by Dr. Zoller, published an amazing argument through soil analysis and meteorological research on Hawaii Island. Most of Hawaii Island is formed by dust blown by China. The doctor explained that in China, every spring is a season of frequent sandstorms, and a large amount of dust is driven out of the desert in China, forming thick clouds hundreds of miles wide in the air. This huge cloud was blown by strong winds across the North Pacific to gulf of alaska, then moved south, and finally landed near Hawaii, forming the island year after year.

■ No.9 Natural Beauty Island

There is a Balcalo Island in southern Italy. A long time ago, due to the volcanic eruption on the island, lava flowed down the mountain to form mud and accumulated in more than a dozen pools. These mud can whiten and moisturize, make the skin tender and smooth, and can also treat women's low back pain and lose weight, so it is called a natural beauty island.

Because of the beauty function of Balcalo Island, it attracts thousands of tourists who love beauty at home and abroad. Every summer, more than a dozen mud ponds on the island are crowded with people from all over the world, countless men, women and children, rolling in the mud ponds and smearing foam on their bodies and faces to make their skin whiter and more delicate.
