Rivers

The rivers all come from one source whitch is normaly under ground. Rivers can also come from upper level sources but that is realy rare to find in fact only 20 people have ever seen an upper level source. When a river begins it is usualy a huge one, lots of river sources are always making another route (when a flood happens) and that usually makes the river even bigger. Most rivers get bigger though when they create a water fall: a huge change in water. A river is natural wartercourse,usually freshwater,flowing towardsvon ocean,a lake,a sea,or another river. The part of a river that flows into the sea is called the mouth of the river.
