Describe a scenario where GPS navigation might fail and how you would overcome it.

• GPS loses signal in a dense forest; use a map and compass to navigate

• GPS battery dies; wait until it recharges

• GPS shows incorrect coordinates; ignore and continue

• GPS is too slow; walk faster to compensate

Answer explanation

In dense forests, GPS signals can be lost due to obstructions. The best way to navigate in such situations is to rely on traditional methods like using a map and compass, ensuring you can find your way without electronic assistance.

How can geocachers ensure they leave no trace in the environment?

• By hiding caches in sensitive areas

• By taking only photos and leaving only footprints

• By marking trees with paint

• By creating new trails

Answer explanation

Geocachers can ensure they leave no trace by taking only photos and leaving only footprints, which minimizes their impact on the environment. The other options, like hiding caches in sensitive areas or marking trees, can harm nature.
