Name three common terrain features found on topographic maps and explain how each affects movement and visibility.

• A. Hill gives elevated vantage point; saddle connects ridges; valley constrains movement and provides concealment.
• B. River delta indicates water hazards that always slow all movement.
• C. Plateau provides no influence on visibility.
• D. Cliffs always increase visibility and safety.

Answer: (A)

On topographic maps, hills, saddles, and valleys are common because elevation changes shape both how you move and what you can see. A hill gives you an elevated vantage point; from the top you can spot approaches and threats from farther away, but moving uphill slows you and the slope can expose you to observation from higher ground. A saddle is the low point between two ridges, often used as a pass; it can make movement more efficient than scrambling over a peak, but the sides limit sight along the ridges and the narrow pass can become a choke point where movement concentrates. A valley follows a stream and runs between higher sides; traveling along the valley floor is usually easier, and vegetation and terrain offer concealment, but visibility into the surrounding terrain is reduced because the higher sides block lines of sight. These features show how elevation and terrain shape both movement options and how well you can observe the area.
