Iceberg - Structure, Formation, Calving | Britannica Iceberg - Structure, Formation, Calving: A newly calved Antarctic tabular iceberg retains the physical properties of the outer part of the parent ice shelf The shelf has the same layered structure as the continental ice sheet from which it flowed All three features are topped with recently fallen snow that is underlain by older annual layers of increasing density Annual layers are often
Iceberg - Arctic, Melting, Calving | Britannica Iceberg - Arctic, Melting, Calving: Most Arctic icebergs originate from the fast-flowing glaciers that descend from the Greenland Ice Sheet Many glaciers are funneled through gaps in the chain of coastal mountains The irregularity of the bedrock and valley wall topography both slows and accelerates the progress of glaciers These stresses cause crevasses to form, which are then incorporated
