FROZEN
WORLD
Almost 70 percent
of Earth’s fresh water is frozen
into solid ice. Most of it forms ice
sheets and glaciers in the Arctic,
Antarctic, and high mountains.
But just a few thousand years ago,
these ice sheets were far larger.
The land they once covered
still bears the scars of
these ice ages.
