Ye Chao likes this icy world very much......

It's cold, but it makes it look holy and clean.

Of course, there are very few places to live, but that's not the point, the important thing is that it looks beautiful.

Greenland's ice-free area covers an area of 341,700 km², but most of the north and east coasts are almost inaccessible and frigid wastelands.

The inhabited area is about 150,000 square kilometres, mainly in the southern part of the West Coast. The island is a vast island with a wide range of climates between regions, and Greenland, located in the Arctic Circle, has polar day and night phenomena that are unique to the polar regions.

The inhabitants are mainly located in the west and southwest, with the Inuit (Eskimo) being the majority. The west coast is home to the world's largest fjord, 322 kilometres inland. It is home to most of the settlements, including its capital, Gotthob, which has a population of about 12,000 people.

Two-thirds of the island is north of the Arctic Circle, and the climate is cold, with only the southwest without permafrost. About four-fifths of Greenland's land is covered by ice, with a maximum thickness of 3,411 meters in the middle and an average thickness of nearly 1,500 meters, making it the largest modern continental glacier after Antarctica.

The Inuit (Eskimos) first arrived here in 3000 BC. In 1894 Denmark first established a colony on the southeast coast of the island, and in 1921 Denmark declared exclusivity, but in 1979 the Danish government allowed Greenlanders to govern themselves and passed the "Greenland Self-Government Ordinance".

Greenland is a region of towering mountains, massive blue-green icebergs, magnificent fjords, and barren bare rocks.

From the air, it resembles a vast, empty wilderness, where jagged black peaks occasionally pierce white dazzling and infinitely stretching ice fields. But from the ground, Greenland is a very different island: in summer, the meadows near the coast bloom with purple saxifrage and yellow poppies, as well as shrub-like montane cines and birches.

However, central Greenland is still enclosed in a huge ice sheet, and it is impossible to find a single meadow or a small flower for hundreds of kilometers. Greenland is an incredibly beautiful island with huge geographical differences.

The eastern coast has been clogged with impassable ice for many years, and it is inaccessible due to the harsh natural conditions and difficult transportation. This makes this vast area a natural refuge for some of the Arctic's endangered plants, birds and mammals.

The minerals are most prestigious for cryolite. Aquatic products are abundant, such as whales and seals.

According to foreign media reports, scientists recently found that Greenland was formed 3.8 billion years ago, and its predecessor was an undersea continent, which was formed due to the collision of continental plates, which made Greenland the oldest island in the world.

Scientists say the findings suggest that the Earth's continental plates moved much earlier than we thought, and that Greenland was formed by the collision of continental plates.

Scientists came to this conclusion after analyzing some ancient rock fossils found in Greenland.

They say the ancient fossils are hidden beneath Greenland, and they are arranged like a neat dike. Through the analysis of these rocks, scientists have confirmed that the origin of Greenland is much more complex than one might think, and that it may be the result of the movement of crustal plates, which are quite long and complex.

According to scientists, these ancient fossilized rocks found in Greenland can only be produced as a result of collisions during the movement of continental plates, which scientists call serpentine.

Serpentine is a rock formed by the collision of two continental blocks against each other, and it can be concluded that Greenland may have been an underwater continent in ancient times.

Professor Harred Furns, who led the study, said of the study, "The discovery of ophiolite on Lingland Island is a breakthrough in our focus on the island.

These ophiolite fossils found in the southeast of Greenland are the oldest ophiolite on Earth, and Greenland is the first island on Earth to be formed as a result of the collision of crustal movements that turned out to be an undersea continent. Based on the age and weathering of these fossils, we preliminarily conclude that they were formed 3.8 billion years ago.

The findings, published in the latest issue of the journal Science, claim to have a significant impact on the evolution of the Earth and the history of life on Earth.

Previously, most experts believed that life arose in warm places on Earth, because such places help organisms absorb nutrients from the outside world, and the environment also helps organisms to reproduce.

According to the theory of earth building, the surface continent of the earth is like a tangram, which is made up of many small pieces, and these pieces are in motion all the time, but the speed of movement is very slow and you can't feel it.

Due to the movement of the continental plates, strong volcanic or seismic phenomena often occur at the junction of many plates. On the other hand, it is precisely because of the movement of the continental section that many new continents have been created. Some scientists have also said that before the movement of the blocks, the earth was just a vast ocean.

The question of exactly when the movement of the earth's crustal plates began has been a point of debate among scientists, because the Earth's surface must be cold enough to form solid land. Most scientists agree that this event began late, as the world's earliest ophiolite was formed 2.5 billion years ago.

Jennifer Carlson, a structural geologist at Syracuse University in New York, said, "There is still a lot of debate in the academic community about when the movement of the earth's crustal plates began. This discovery in Greenland provides new evidence for the idea that the movement of the earth's crustal plates occurred in the early days.

But it also points out that the discovery of Greenland only shows that the movement of the plates on the seafloor began a long time ago, but not that other forms of plate movement also began very early, and it is a very good material for studying the structure of the early Earth.

With the deepening of the study of ophiolite excavations in Greenland, scientists have gradually turned their attention to the impact of the movement of the earth's crustal plates in ancient times. "We may be able to analyse some of the information about life forms from ancient times from the chemical composition of the ophiolite in Greenland," Professor Ferns said.

Previously, some geoscientists believed that life on Earth multiplied due to the movement of the earth's crust.

Carlson also said that in ancient times, submarine ridges were a breeding ground for early organisms, and the effects of various environmental changes from the outside world could only involve the surface of the ocean, but not the underwater world.

Greenland is about 2,670 kilometers long from north to south, more than 1,050 kilometers wide from east to west, about four-fifths of the area is within the Arctic Circle, and the northernmost point is less than 800 kilometers from the North Pole. Greenland is only 26 kilometres north of Canada's Ellesmele Island.

The nearest European country is Iceland, located in the southeast of Greenland, across the 320-kilometre-wide Danish Channel. Greenland's coastline is 39,330 kilometres long, roughly equivalent to the length of one circumference of the Earth's equator.

The island is physically connected to the North American continent by a ridge less than 180 meters underwater. The geological structure is an extension of the Canadian Shield. The shield is a rugged plateau in northern Canada made of hard Precambrian rock.

Greenland's most significant geomorphological feature is its vast and thick ice sheet, second only to Antarctica, with an average thickness of 1,500 meters, about 3,000 meters at its thickest point, and an area of 1,813,000 square kilometers, accounting for about 83.7% of the total area of Greenland.

Wind and snow are raging on the bare ice sheet, and the layers of snow are squeezed into ice, constantly moving towards the outer edge glaciers. The Port Jacobs glacier often moves up to 30 metres a day, making it one of the fastest moving glaciers in the world. Ice-free land is found in coastal areas, mostly plateaus.

The mountain range runs parallel to the east and west shores of the island, and the southeastern Mount Combjørens is 3,700 meters high. Despite these plateaus, the rock bottoms of most of the Greenland ice sheets are actually quite or slightly below sea level.

The long, deep fjords jut out into the hinterland of Greenland's east and west coasts, forming a complex system of bays that are sparsely populated but spectacular. In many places along the coast, the ice moves straight towards the sea, and glaciers break off and slide into the water to form large icebergs.

Greenland has a cold polar climate, with only the southwest being slightly warmer due to the Gulf Stream. There is a persistent layer of cold air over the icy interior of the island, and a low-pressure air mass often moves from west to east above the cold air, resulting in a rapidly changing weather, sometimes sunny and sometimes windy and snowy.

The average temperature in winter (January) is minus 6°C in the south and minus 35°C in the north. In summer (July), the average temperature is 7°C on the southwest coast and 3.6°C in the northernmost part. Among them, the coldest central plateau region has the coldest monthly average temperature of minus 43 °C, and the absolute minimum temperature reaches minus 70 °C, making it the second "cold pole" on earth after Antarctica.

The average annual precipitation decreases from 1,900 mm in the south to about 50 mm in the north.

Greenland has a very cold climate, with a total volume of 2,600 trillion cubic meters of ice, according to scientists, and if all this ice melts, all the sea levels on Earth will rise by 6.5 meters.

Greenland relies on a thick layer of ice that allows it to protrude high above sea level. If the ice were removed, Greenland would not be so towering, but would only be fixed to the sea like an oval-shaped plate.

Because there is only snow and no rain all year round, except for a few areas such as the southwest coast, where there is no permafrost and a small number of trees and green space, Greenland is a kingdom of ice and snow. 85% of the island is covered with glaciers and thick icebergs.

Greenland's ice cubes contain a lot of bubbles inside, and when you put it in the water, it makes a constant popping sound and is a very good cold drink. People call it "10,000-year-old ice". This ice is clean and pure, and it is a rare pleasure to take a sip of "10,000 years of ice" on a hot summer day.

Greenland is rich in "10,000-year-old ice", with an average thickness of 2,300 meters, second only to Antarctica's modern giant continental glaciers.

Among the thousands of islands in the world's oceans, Greenland, with an area of 2,166,086 km, is definitely the first, and in terms of size, it is 54,559 km more than the second-ranked island of New Guinea, the third-ranked Kalimantan Island, and the fourth-ranked Madagascar Island. Therefore, Greenland deserves to be called the "Big Brother of the Global Islands".
