Why do we say “tip of the iceberg”?

When we know only a little bit about a big problem, we say it’s just the tip of the iceberg. Icebergs are typically huge. Some are larger than the U.S. state of Rhode Island. One Antarctic iceberg rivals the size of Sicily, the largest island in the Mediterranean. Most of that icy mass lies below the surface of the water. Only about one-eighth of an iceberg – the famous “tip” from the expression – is visible from above.
