What role do mental maps play in Arctic navigation?

• A. They replace reliance on stars with mental maps and landmarks
• B. They rely on GPS
• C. They rely on satellites
• D. They use compasses alone

Answer: (C)

Mental maps are the navigator’s internal picture of where things sit in the world and how a route should unfold. In the Arctic, conditions can make stars hard to observe and magnetic compasses unreliable, so your ability to move confidently depends on grounding that internal map in real position data from satellites. The satellites give you exact coordinates, which you then translate onto your mental map to plot a safe course, anticipate ice edges, and adjust as you go. So the role is to use satellite positioning to anchor and activate your mental map in space. The other ideas don’t fit as well because relying on stars or compasses alone isn’t dependable in polar conditions, and saying you rely on GPS alone is narrower than recognizing the broader satellite-based positioning that makes the mental map actionable.
