Approximately 10% of an iceberg's mass is typically visible above the surface of the ocean.
Understanding Iceberg Buoyancy
The reason icebergs float is due to the unique property of water: its solid form (ice) is less dense than its liquid form (water). This decreased density allows ice to float on water.
As the reference states: "Icebergs float on the ocean with only about 10% of their mass appearing above the ocean; the remaining 90% is concealed beneath the waves." This means that the vast majority of an iceberg's mass and volume is hidden below the water's surface.
Iceberg Distribution
Here's a simple breakdown based on the reference:
- Above Water: ~10% of mass
- Below Water: ~90% of mass
This characteristic is why the phrase "tip of the iceberg" is often used to describe a small, visible part of a much larger, unseen problem.
Knowing that only a small fraction of an iceberg is above water is crucial for navigation and understanding their true size and potential hazards.
