Input: Consider Input: Paragraph- Sent 1: Rivers flowing over gentle slopes move more slowly.
Sent 2: They move much more slowly than a mountain stream.
Sent 3: These slow moving streams create different types of features than mountain streams.
Sent 4: Slow moving water erodes the sides of their channels more than the bottom.
Sent 5: Also, large curves in the stream form.
Sent 6: These curves are called meanders.
Sent 7: Meanders are caused by erosion and deposition.
Sent 8: Remember, faster moving water causes erosion more quickly.
Sent 9: Slower moving water erodes material more slowly.
Sent 10: If water is moving slowly enough, the sediment being carried may settle out.
Sent 11: This settling out, or dropping off, of sediment is deposition.
Sent 12: The curves are called meanders because they slowly wander over the land.
Sent 13: As meanders erode from side to side, they create a floodplain.
Sent 14: This is a broad, flat area on both sides of a river.
Sent 15: Eventually, a meander may become cut off from the rest of the river.
Sent 16: This forms an oxbow lake.
Question: What are the two processes that form large curves in streams? (A) Meanders and floodplains (B) Erosion and deposition (C) Slow moving streams create different types of features than mountain streams, Slow moving water erodes the sides of their channels more than the bottom (D) River water flowing over gentle slopes, forming of meanders.
