 * Stream Order** is important because it is one of the most important aspects of physical geography because it has to do with one of the earth's most important resources, water. Stream Order is used by geographers,geologists, and hydrologists alike use the Stream Order. It is often called the Strahler Order or the Horton Strahler order. The system is simple a first order stream is a stream with no tributaries it is essentially the building block of the Strahler order. When two first order streams join together they form a second order stream. When two second order streams join together they form a third order stream. But when a secon and first order stream come together they remain a second order stream. These two basic rules goes for all higher orders of streams so :
 * 4+4=5

Then a map can be created and they look something like this **
