Explanation:

To solve these fill - in - the - blank questions about navigational tools, we analyze each one:

Question 2

A compass uses a magnetic needle to point to the Earth's magnetic north pole. The magnetic needle is a key component of a compass that aligns with the Earth's magnetic field, allowing it to indicate the magnetic north direction.

Question 3

A compass does not give distances, it just shows the direction (specifically the direction to magnetic north) to north. Its main function is to indicate the magnetic north - south direction, and it has no mechanism to measure distances.

Question 4

Telescopes enlarge and make celestial objects clearer. Telescopes use optical or other technologies to collect and focus light from celestial objects, thereby magnifying them and making details more visible, which is very useful for observing stars, planets, and other celestial bodies during navigation (especially for more detailed observations compared to the naked eye).

Answer:

s:

1. magnetic needle
2. direction
3. Telescopes
