Lots of tributaries joining 3rd order streams To travel across Quick or sudden Side view of the area showing the changing elevations Small 1st and 2nd order streams that join larger streams Series of bends or turns Sediments that were released Area of flat land found on either side of a river Fan-shaped area of sandy/muddy sediment built up into the open water where a stream meets the sea A truncated section of a meander in the stream channel which forms a ‘c’ shape. This stage represents the early stages of a stream where most of it energy is used to downcut, or erode, a narrow V-shaped valley.

Due to the steep gradient of this stage water velocity is very fast. During this older stage the stream usually comes to an end when the flow enters a sea or lake. This is known as the mouth of the stream.
