Which instrument is used for navigation to determine direction?

• A. Compass
• B. Astrolabe
• C. Igloo
• D. Tipi

Answer: (A)

Determining direction in navigation is done most directly with a compass. A compass uses a magnetized needle that aligns with Earth’s magnetic field, pointing toward magnetic north so you can read a bearing and head in the chosen direction. This works under many conditions and is portable, making it a fundamental tool for finding your way on land or at sea. An astrolabe, while useful in navigation for figuring out latitude and time by measuring the altitude of celestial bodies, doesn’t give you an immediate direction to travel. The other two options are shelters, not instruments, so they don’t provide navigation guidance.
