Solved cryptogram
Nearly all of the water on Earth is salt water, and a sliver of the rest is locked up as ice.
Earth Science Facts, sourced to U.S. Geological Survey.
What it means
About ninety seven percent of the water on this planet sits in the oceans. Of the small remainder, the bulk is frozen in glaciers and ice caps or held underground, and the fresh surface water in every lake and river on Earth is a rounding error on a rounding error. Gathered into a single ball, all the water on Earth would make a sphere a little under fifteen hundred kilometers across.
The claim comes from U.S. Geological Survey, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
