What
is a key?
A
"key" is an island where there is no natural source of
fresh water.
The
Florida Keys are "islands" formed by ancient coral
reefs. At one time, all of what is now Florida was beneath the
surface of the ocean. During that time, massive coral reefs were
formed. As the water level on the whole planet subsided, the tops
of these reefs were no longer covered by water. Over time,
sediment, seeds deposited by birds, and "nature"
produced the tropical paradise of the Florida Keys. |
