2. What is the submerged proportion?Approximately 90% of mass is below the waterline
3. What is the largest recorded iceberg dimensions?335 km by 97 km
4. How do icebergs form?Icebergs form when a glacier or ice shelf cracks and a large piece breaks off. This breaking is called calving.
5. Why are most of an iceberg underwater?Because ice is lighter than saltwater, about 90% of an iceberg’s volume stays below the surface to balance its weight. Only about 10% can be seen above the water.

Archimedes' Principle: A body wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced.
Hydrostatic Equilibrium: The state where the buoyant force acting on a floating object balances its weight.
Paleoclimate Research: The study of past climates, often using natural archives like ice cores and ocean sediments.
