Which terrain feature is a stream course that is less developed than a valley and has no level ground?

• A. Fill
• B. Draw
• C. Ridge
• D. Valley

Answer: (B)

Drainage patterns and ground level define this concept. A draw is a small, narrow stream channel with steep sides and no level ground—the land around it slopes down into the channel, so there isn’t a flat, open floor like you’d find in a valley. That makes it the best match for a stream course that’s less developed than a valley and has no level ground. Valleys are broader, with flatter bottoms and some level ground; ridges are high, elongated crests of land; fill refers to earth moved to create level ground and isn’t a natural stream channel. So the draw best fits the description.
