Question

A. To measure distance from the equator
B. To measure distance from the prime meridian
C. To indicate elevation above sea level
D. To show time zones

Answer

The correct answer is To measure distance from the prime meridian.

Explanation

The correct option is To measure distance from the prime meridian. To measure distance from the prime meridian is correct because it directly matches the approved learning objective to use and understand latitude and longitude coordinates. This belongs to Cartographic skills within Cartographic skills, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Cartographic skills, reverse the geographical relationship, or make a broader claim than the objective supports.

Common mistake

Confusing Latitude and Longitude

Students often mix up latitude and longitude coordinates, thinking they are interchangeable.

Remember that latitude lines run horizontally and measure north or south of the equator, while longitude lines run vertically and measure east or west of the Prime Meridian.
