Types of water
By George, Barney and
Molly
The topic we will be
starting with is rivers.

Rivers have been used as a source of water, for
obtaining food, for transport, as a defensive
measure, for bathing, and as a means of disposing
waste (Wikipedia).

A river is a natural watercourse, usually freshwater,
flowing towards an ocean, a lake, a sea, or another
river. In a few cases, a river simply flows into the
ground or dries up completely before reaching
another body of water.

Small rivers may also be called by several other
names, including stream, creek, brook, rivulet,
tributary and rill; there is no general rule that
defines what can be called a river, although in some
countries or communities a stream may be defined
by its size.

Water springs
A water spring is a pool of fresh
water. When this pool
overflows it forms a river
which then travels down the
mountain starting the water
cycle.

Artificial lake: A lake created by flooding land behind a
dam, called an impoundment or reservoir,
Lava lake: A pool of molten lava contained in a volcanic crater or other
depression. Lava lakes that have partly or completely solidified are also
referred to as lava lakes.
Snow and Ice
Snow is formed
when the
clouds get
really cold and
it rains then
the rain is
turned into
snow instantly
Ice is water
frozen into
the solid
state. Ice
appears in
nature in
forms of
snowflakes,
hail, icicles,
glaciers,
pack ice,
and entire
polar ice
caps.
Mist and fog
Mist is a lots of
small droplets
suspended in air.
It can occur as
part of natural
weather or
volcanic activity,
and is common
in cold air above
warmer water
Fog is a
collection of
water droplets
or ice crystals
suspended in
the air at or
near the
Earth's surface
Rain

Rain is very important
to people and animals
all over the world.

Rain drops range in
size from oblate,
pancake-like shapes
for larger drops, to
small spheres for
smaller drops.
