The
Hydrosphere is the Earth's
water envelope. The
Hydrosphere contains mostly the
seas and
oceans that surround the
Earth's continents. The
Hydrosphere also contains the small percentage of the Earth's
water that exists underground.
Streams and Lakes are made up of only 1% of the
Hydrosphere but they are the Earth's greatest landscape changer and provide
drinking water for
humans and
animals alike and important animal
habitats.
Other
noders should feel free to elaborate.
