The box below that one would be canyon.
And the farthermost box to the right would be delta.

Water typically runs through a canyon and the lines appear to be separating for the water.
Deltas are wetlands that form from rivers emptying their water into another body of water. If you were to look up an image of a delta that would make it easier to understand, it also looks like what the image provided is trying to demonstrate.
