The three largest glaciers in the world are:
1. Antarctic glaciers.
The largest glacier on Earth is the Antarctic Glacier, which accounts for the entire Antarctic continent.
98% of the ice, known as the "Antarctic Ice Sheet", has a diameter of about 4,500 kilometers and an area of about 13.98 million square kilometers.
It occupies about 98% of the Antarctic continent. The average thickness is 2000 to 2500 meters, and the maximum thickness is more than 4000 meters. The total volume of the ice sheet is about 24.5 million cubic kilometers, accounting for 90% of the world's land ice and 70% of the world's total freshwater.
2. Greenland glaciers.
The second largest is the Greenland glacier near the North Pole, Greenland.
It covers 1.7 million square kilometers.
The ice sheet is almost the size of Mexico, and the ice crust is 3 kilometers thick. Once it melts, global sea level.
will **7 meters.
3. Vatnajökull glacier, Iceland.
Vatnajökull covers an area of 8,300 square kilometers near the town of Hofen in southeastern Iceland, and is not only the largest glacier in Iceland, but also the largest glacier in Europe and the third largest glacier in the world.
Formation of glaciers:
Glaciers are a form of water that is transformed by snow through a series of changes. To form a glacier, there must first be a certain amount of solid precipitation, including snow, fog, hail, etc. Without enough solid precipitation as a "raw material", it is equivalent to "cooking without rice", and it cannot form a glacier at all.
In the high mountains, glaciers can develop, and in addition to a certain altitude, the mountains are not too steep. If the mountain peaks are too steep, the snow will fall down the slope and will not form snow and form glaciers. As soon as the snowflakes fall to the ground, they change, and as the external conditions and time change, the snowflakes will turn into spherical snow that completely loses its crystal characteristics, which is called granular snow, and this snow is the "raw material" of glaciers.

The world's three major glaciers are the Antarctic Glacier, the Greenland Glacier, and the Vatnajökull Glacier in Iceland. Among them, the Antarctic glacier is the largest glacier on the earth, accounting for 98% of the entire Antarctic Continent, called the "Antarctic Ice Sheet", with a diameter of about 4,500 kilometers and an area of about 13.98 million square kilometers, accounting for about 98% of the area of the Antarctic continent and so on.
The average thickness of Antarctic glaciers is 2,000-2,500 meters, with a maximum thickness of more than 4,000 meters. The total volume of ice sheets is about 24.5 million cubic kilometers, accounting for 90% of the world's land ice and 70% of the world's total freshwater.
Greenland glaciers are the second largest glaciers in the world. Greenland is covered with 1.7 million square kilometres of ice sheet, almost the size of Mexico, and the crust is 3 kilometres thick. Once it melts, the global sea level will be **7 meters.
Vatnajökull covers an area of 8,300 square kilometers near the town of Höfen in southeastern Iceland, and is not only the largest glacier in Iceland, but also the largest glacier in Europe and the third largest glacier in the world.

<> "The World's Largest and Most Spectacular Glacier.
The glaciers cover an area of 4,457 square kilometers. Bordered to the west by the Chilean border, there are several peaks from north to south, which are the birthplace of several glaciers. The eastern part of the glacier group is led by Lake Argentina, which is dotted with many glaciers, all of which were formed during the Quaternary glacial period and are the home of all glaciers.
Every two or three years, the Moreno Glacier cuts off Lake Argentina, causing the water level to rise until the water level returns to normal when the water hollows out the bottom of the ice dam and the ice dam collapses and the lake is back open. After the ice dam collapses, the glacier continues to push forward, and over the years it cuts off the lake again, flooding the valley forests around the lake.
The largest glacier in the group is the Uppsala Glacier, which extends to the northern tip of Lake Argentina, and is often filled with huge blue icebergs that flow into the lake, causing the lake to float on the surface of the lake that is formed by the breakdown of the glacier.
1. Crystal ice cubes of different shapes. Some ice blocks form ice walls, more than 80 meters high, and slowly move forward, with an average speed of 2-3 meters per day.

The largest glacier in the world in Antarctica is the Lambert Glacier.
Lambert Glacier is the largest and longest glacier in the world, and this glacier was discovered by a group of Australian pilots between 1956 and 1957. The glacier is filled in a huge faulted valley 400 km long, 64 km wide and 2,500 m deep.
The Lambert Glacier flows into the sea at an average annual velocity of 350 meters. Glaciers flow slowly. The fastest flowing glacier in the world is the Esbray Glacier in Jacobs Harbor, Greenland, which flows 7 kilometers per year, while the Lambert Glacier glides over Mount Charles at a rate of about one kilometer per year, and finally accelerates to 1 kilometer per year in the Amery Ice Front Zone, although it is not a fast-moving river, it is a hugely moving glacier, with about 35 cubic kilometers of ice passing through the Lambert Glacier every year.
The ten wonders of the world are the Egyptian Pyramids, the Cosmic Statue, the Faros Lighthouse, the Hanging Gardens of Babylon, the Temple of Artemis, the Colossus of Rhodes, the Mausolos Tomb Temple, the Great Wall of China, the Faros Lighthouse, the Alexandra Harbor, and the Terracotta Warriors and Horses.
