Berges are a type of large, floating ice mass that breaks off from glaciers or ice shelves. They can vary in size, shape, and color, often appearing blue due to the compression of ice. When berges drift into warmer waters, they can melt and contribute to rising sea levels. These ice formations are commonly found in polar regions, particularly in areas like Antarctica and Greenland. Berges play a significant role in the Earth's climate system, as they reflect sunlight and help regulate ocean temperatures. Their movement and melting patterns are closely monitored by scientists studying climate change.
