Streams and Rivers
A stream or river is a body of water that flows in one direction. Usually they begin at springs, lakes or where snow
melts. These are called headwaters. They then travel toward another type of water channel or ocean, this is called a mouth.
Streams and rivers change as they make their way from the headwater to the mouth. In the beginning of their journey,
the water is cooler, cleaner, and has a higher level of oxygen. In the middle of the journey, the width of the river or stream
widens. Here a majority of aquatic plant life can be found. Finally, toward the mouth of the river or stream, the water
becomes warmer, murky, and has less oxygen.

A wetland is an area of still or standing water. Some types of wetlands include swamps, marhes or bogs. Areas around
wetlands are very moist and very humid. Unlike ponds, lakes, streams, and rivers, wetlands can also have some salt content.
These unique areas are called salt marshes.
