loop to the other pursuing a direct course. The still water left over at the cutoff is this and makes a U
shape.
Flood Plain - ANSWER Flat are nearest to a river course that are flooded periodically. Soils more fertile
because of frequent deposits of silt. Agriculture thrives here.
Riparian Forrest - ANSWER Riverside forest that are species rich.
