But you may be struggling to understand some of the finer details of melting ice, such as the difference between icebergs and ice floe. An iceberg is a large mass of freshwater ice that has broken off of a glacier or an ice shelf. An ice floe is a large, flat pack of floating ice.
While it is true that both glaciers and ice floes are large masses of ice that can be found in arctic regions, there is a major difference between them. Basically, glaciers originate on land, and ice floes form in open water and are a form of sea ice.
When strong winds in the Arctic and Antarctic regions force icebergs and sea ice away from the coasts and out to sea, areas of open water remain where air and water are in direct contact with each other. These areas are called coastal polynyas, and they are the places where sea ice is created.
Icebergs are a prime example of an environmental phenomenon that brings together multiple disciplines in the polar sciences, from the physics of calving and melting to the geology of their solid deposits and sea-floor interactions.
14.1 Types of Ice – Introduction to Oceanography. The ice that is seen floating on the ocean’s surface comes from one of two sources. Glacial ice is formed from the accumulation and compression of snow into glaciers, that then break apart and release ice to the ocean.
5 lut 2018 · Ice shelves are permanent floating ice sheets that extend from icy land masses. They form from ice sheets that slowly flow to the sea after breaking off from glaciers or being carved by ice streams. If they don’t melt when they reach the ocean, they can continue to grow into large thick ice masses.
9 kwi 2024 · Explain the differences between Sea Ice (Pack Ice) and Glacial Ice (Icebergs), detailing their formation processes and sources. Difficulty: Medium Describe the classification of icebergs based on size and shape, and discuss how their movement is influenced by ocean currents and wind.
