Points A and B are locations at the edge of a stream. The data table gives the depth of the water and distance from point A, in feet, along line AB
Using the map and the data table, explain why the depth of water 20 feet from point A is different from the depth of water 20 feet from point B.
-More deposition occurred on the inside of the meander
-Stream water moves slower on the inside curve
-More erosion occurs on the outside of a bend

Explain why the stream meanders on the floodplain, but not in the mountains.
— The stream began to flow over a nearly flat landscape.
— Stream velocity decreased.
— Gradient decreases from the mountains to the floodplain.
— The stream flows more slowly on the floodplain.
