The position of the sun at noon is used to determine:

  1. Latitude

  2. Longitude

  3. Both latitude and longitude

  4. Neither latitude nor longitude


Correct Option: A
Explanation:

The position of the sun at noon can be used to determine latitude, but not longitude.

The position of the stars is used to determine:

  1. Latitude

  2. Longitude

  3. Both latitude and longitude

  4. Neither latitude nor longitude


Correct Option: C
Explanation:

The position of the stars can be used to determine both latitude and longitude.

A sextant is used to measure:

  1. The angle between the horizon and a celestial body
