What is an iceberg What does an iceberg mean

Icebergs are large chunks of freshwater ice that break off the seaward end of a glacier or polar ice sheet and fall into the sea, usually in polar regions. In fact, the iceberg is not really a mountain, but a huge block of ice floating in the ocean. In the polar regions, waves or tides in the ocean violently hit the continental glaciers on the edge of the coast, and over time, its front end slowly breaks off and slides into the ocean, where it floats on the surface of the water, forming so-called icebergs.

An iceberg is a large piece of ice that drifts freely in the ocean without a glacier or ice shelf. The density of ice is about 917 kg cubic meters, while the density of sea water is about 1025 kg cubic meters of rubber pavement, according to Archimedes' law.

We know that about 90% of the volume of free-floating icebergs sinks under the surface of the sea. Therefore, it is impossible to guess the shape of the water by looking at the shape floating on the water. That's why the tip of the iceberg is a small part of the problem.

Icebergs are very strong, and the strength of the metal is reduced in the low temperature environment of the polar regions, which can easily damage the metal plates, so it is an extreme risk factor in polar ocean transportation. Freeze.

the formation of mountains; high mountains where the ice does not melt all year round; Glaciers in the polar regions often form huge ice blocks at their mouths, which are broken by the impact of waves and float on the sea, becoming icebergs.

In fact, icebergs are not really mountains, but broken fragments of glaciers that have slipped into the sea. They vary in size, from small pieces of whistling ice that can pose a threat to ships, to large ones that are really like a mountain, some are a kilometer wide or more; The part above the water is 60 meters high, or even higher.

The underwater part of the iceberg is about 7 times the size of the water part. This is because icebergs are caused by ice in freshwater, which weighs about 7 8 of the weight of seawater. If it is in fresh water, about 9 out of 10 of the iceberg will sink below the surface of the water.

The rolling part of the iceberg may be far from the side of the visible part, so the ship may hit it if it gets closer. The giant ship Titanic.

This is how it came to be, sinking in Newfoundland on April 15, 1912.

Nearby, about 1,500 people were killed.

Icebergs are generally found in the Antarctic region, in fact, there is a saying about icebergs called the tip of the iceberg, the top of the iceberg is very large, but the bottom is actually bigger.

Name) The peaks of the frozen mountains are also called ice peaks. Huge blocks of ice floating in the sea. The metaphor is a backer that cannot be relied on for a long time.
