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. |
