In geodesy and cartography, which single statement always holds true for places that have the same geographic latitude?

Difficulty: Easy

Correct Answer: They lie on the same parallel of latitude.

Explanation:


Introduction / Context:
Latitude and longitude define positions on Earth. Questions often test whether candidates can distinguish what “same latitude” guarantees versus what it does not (e.g., meridian or time).


Given Data / Assumptions:

  • Latitude is angular distance north or south of the equator.
  • Parallels are circles of constant latitude.
  • Local solar time depends primarily on longitude, not latitude.


Concept / Approach:
Any two points with the same latitude lie on the same parallel, a small circle parallel to the equator. This is the only universally true statement among common misconceptions about meridians and time.


Step-by-Step Solution:
1) By definition, “same latitude” ⇒ same parallel.2) Meridians are lines of constant longitude; same latitude does not imply same longitude.3) Equal local solar time requires equal longitude, not latitude.4) Being equidistant from both poles is only true at the equator; elsewhere distances differ.


Verification / Alternative check:
On a globe, draw any parallel (say 30°N); cities along it share that latitude but span many longitudes and time zones.


Why Other Options Are Wrong:
Option B/E: Same latitude does not fix longitude or meridian.Option C: Only the equator is equidistant from both poles.Option D: Local solar time varies with longitude.


Common Pitfalls:
Assuming shared climate or time zones from latitude alone; these depend on longitude and other factors.


Final Answer:
They lie on the same parallel of latitude.
