Icebergs are large masses of freshwater ice that break off from glacial ice sheets or ice caps. They are significant components of the Earth's cryosphere, representing frozen freshwater stored in massive terrestrial formations. Their formation involves the slow flow and fracturing of glacial ice over geological timescales. Due to their massive volume and density, they float in the ocean, and their submerged portions are generally much larger than the visible sections. The eventual melting and dispersal of these structures play a crucial role in global ocean salinity, sea level dynamics, and the transfer of cryospheric material into marine environments.
