Which terrain feature is formed when material is added to raise a low area to a level surface?

• A. Saddle
• B. Draw
• C. Fill
• D. Cut

Answer: (C)

The main idea is earthwork grading: you can either cut (remove material) or fill (add material) to reach the desired surface. When you add material to raise a low area up to a level surface, you’re performing a fill. A saddle is a natural low point between two hills, not defined by adding material. A draw is a drainage channel. A cut is the opposite of fill, removing material to lower the ground. So the term that fits the scenario is fill.
