iceberg it is a big piece of ice that breaks off from polar glaciers and roams through the arctic oceans.
Etymologically, the word iceberg is formed by the union of two other words: the English ice, which means "ice"; and from dutch and german berg, which means "mountain". I.e, iceberg means "ice mountain".
You icebergs (or icebergs, in Portuguese spelling), are composed of solidified fresh water and exist in almost all arctic environments on the planet, except in the North Pole, where ice forms ice floes, that is, ice shelves formed from seawater frozen during the winter.
These huge blocks of ice can come in many shapes and sizes, which usually indicate their origin and age.
Only 10% of the iceberg is visible on the surface, with 90% of its volume immersed in water. For this reason, icebergs are considered a great danger to maritime navigation.
Because of this characteristic of the icebergs, came the popular expression: "this is just the tip of the iceberg", which means that something is just the beginning or a small part of a much larger and complex problem or situation.
You icebergs they move in the oceans through ocean currents, which influence the submerged part; or by great gales, acting on the immersed part and determining the speed of the ice block.
Since the big accident with the ocean liner Titanic, in 1912, who collided with a iceberg and sank in the North Atlantic, the International Ice Patrol was created to monitor the icebergs of the Atlantic Ocean.
organizational iceberg
The concept of iceberg organizational is widely used in the business field to explain the constitution of a company.
Making an analogy to iceberg, the smallest part of the ice block, which is visible under the waterline, represents a company's results and which are presented to the public and the media.
most of the iceberg, which is below the waterline, symbolizes the structure and organization of the company, responsible for the results of the "surface of the iceberg". This part represents all the "invisible" sectors of a company.
