Answer 1

mature

Step-by-step explanation:

The mature stage of a stream is the second stage of its development. At this stage, the stream had already managed to create its own valley, which is flat and the stream is flooding it occasionally. The surrounding area around the valley though still tends to be higher, and the valley is not very wide, thus having the U-shape. Another characteristic of a mature stream is that it has started to meander. The meandering is at the beginning phase, so it has slight curves which are not moving away a lot sideways.
