How does Archimedes’ principle explain why icebergs float?

Archimedes’ principle states that an object will float if the buoyant force acting upon it—which is equal to the weight of the displaced fluid—exceeds the object's own weight.1

Icebergs float because ice is less dense than liquid water. While liquid water has a density of approximately 1,000 kilograms per cubic meter, ice has a lower density of about 917 kilograms per cubic meter due to the open, hexagonal lattice structure formed by hydrogen bonds as water freezes. Because the ice is less dense, the buoyant force exerted by the displaced water is sufficient to support the weight of the iceberg, allowing it to remain afloat.1
