Final answer:
Latitude can be determined using celestial objects while longitude requires time-keeping devices.
Step-by-step explanation:
True. Latitude is easily determined using celestial objects because it measures the angular distance north or south from the equator. Celestial objects such as stars and the Sun have a fixed position in the sky based on their celestial coordinates of declination and right ascension.
On the other hand, longitude is not easily calculated using celestial objects and requires time-keeping devices. Longitude measures the angular distance east or west from the Prime Meridian, which is a line passing through the Royal Observatory in Greenwich, England.
