An iceberg is a glacier that breaks off from a glacier or ice shelf and floats away in the ocean. These large chunks of ice can be found in polar regions and are a common sight in Arctic and Antarctic waters.
When a glacier flows into the sea, it breaks off chunks of ice at the edge, forming icebergs in a process called calving. The icebergs then float away from the glacier and into the open ocean.
Icebergs are formed when large pieces of ice break off of glaciers. These chunks of ice will begin to float away until they reach the ocean.
Icebergs are large pieces of ice that break off from glaciers or ice sheets and float in the ocean. Most of an iceberg is underwater, with only about 10% visible above the surface. They can be dangerous to ships because of their size and the potential for hidden, submerged ice.
The process of forming an iceberg is called calving. This occurs when chunks of ice break off from the edge of a glacier or ice shelf and float away as icebergs.
Glaciers and erosion are both natural processes that shape the Earth's surface over time. Glaciers, however, are large bodies of ice that flow slowly over land, eroding and reshaping the landscape through the movement and melting of ice. Erosion, on the other hand, refers to the process of wearing away and transporting rock and soil by natural forces like water, wind, and ice, and can occur in various forms beyond just glaciers.
They gradually erode (wear away) due to the forces of nature. Air moves pieces of rock and loose chunks, Water washes away rock and loose chunks, Rocks make cracks in other rocks as they fall, and water seeps into cracks and breaks rocks off when it freezes, because ice expands when it freezes.
A glacier is a frozen river, which forms in freezing conditions high up in mountains. As it reaches lower altitudes, it may melt. However, in some parts of the world, especially in Greenland and in Antarctica, the air is so cold that the glacier can reach the sea and remain frozen. When this happens, the glacier pushes the frozen water out into the ocean. Eventually, under the influence of wave action or internal stresses, a lump of ice breaks off. This process is known as calving. The lump of ice is now free to float away. It is called an iceberg.
Icebergs break away from Antarctica regularly, because they are the glacial ice-river flows from its glaciers. When the bergs lose their 'land footing' and float into sea water do to this flow, soon enough the sea water's action breaks away the 'tongue' and an iceberg will float freely.
