Q: Rivers flowing over gentle slopes move more slowly. They move much more slowly than a mountain stream. These slow moving streams create different types of features than mountain streams. Slow moving water erodes the sides of their channels more than the bottom. Also, large curves in the stream form. These curves are called meanders. Meanders are caused by erosion and deposition. Remember, faster moving water causes erosion more quickly. Slower moving water erodes material more slowly. If water is moving slowly enough, the sediment being carried may settle out. This settling out, or dropping off, of sediment is deposition. The curves are called meanders because they slowly wander over the land. As meanders erode from side to side, they create a floodplain. This is a broad, flat area on both sides of a river. Eventually, a meander may become cut off from the rest of the river. This forms an oxbow lake. <sep>Will water flowing over gentle slopes erode more of the sides of their channels or the bottom?<sep>The bottom
A:
No
