Glaciers are icebergs that flow ashore. They are found in high mountains and polar regions. Glaciers usually range in thickness from one meter to three kilometers; They range in size from a few kilometers to hundreds of kilometers. Mobility varies from one centimeter to one meter per day. Glaciers are found on all continents except Australia. Glaciers are the largest source of fresh water on Earth. Glaciers are the second largest body of water on Earth after the oceans.
Icebergs are formed by the breaking of glaciers. Thus, most of the icebergs that separate from the glaciers and flow into the sea are submerged. The Titanic, described as “never sinking,” sank on its first voyage, sinking two hours and 40 minutes later on April 15, 1912, killing 1,517 of the 2,223 passengers on board.
The state of Alaska in the United States is famous for its many glaciers. That is why Alaska is called the land of glaciers. The largest glacier is in Antarctica. It is called the Lambert Glacier. Greenland has one of the fastest glaciers in the world. Named Jakobshavn Isbræ, it has a top speed of about 20 meters per day. However, due to the specificity of certain terrain, glaciers may accelerate even faster.
There are many glaciers in India too. The Ganges originates from the glacier Gangotri. The Yamuna also originates from the Yamunotri glacier. These rivers flood during the summer when the glaciers melt more. Sometimes glaciers can cause serious environmental problems. One of them is the “glacier lake” flood or “glove”.
Glacial Lake Outburst Flood (GLOF) is the rapid release of large amounts of water stored in glaciers. The intensity of the catastrophe is exacerbated by the fact that each glacier can hold hundreds to millions of cubic meters of water, even though they vary in size. Due to global warming, icebergs melt and glaciers form on the lake. Golf is the sudden flooding of rivers by breaking the walls of such lakes due to avalanches or earthquakes. Usually when an iceberg falls, there is no such thing as a big flood.
When do glaciers collapse?
Glaciers can rupture for a variety of reasons. Erosion at the bottom of glaciers, rising water pressure, ice or rock currents, earthquakes, and climate change are all factors. Danger can occur when two glaciers collide and mix with large amounts of water. Glaciers can have currents lasting from a few minutes to hours and days.
Rivers flooding is common during the summer when glaciers melt more. It is impossible to predict the amount of water in glaciers and to predict avalanches due to unpredictable natural disasters such as earthquakes. Unexpected glacial eruptions cause water levels in the river to rise and cause severe flooding. Due to this, the settlements in the foothills of the hill are flooded and the disaster intensifies .. !!
