Longitude coordinates are always accompanied by which directional indicators?

Longitude coordinates are always accompanied by which directional indicators?

• A. They have E or W next to the numbers.
• B. They are measured in kilometers.
• C. They include N or S.
• D. They use decimal degrees only.

Answer: (A)

Longitude lines indicate how far east or west something is from the Prime Meridian in Greenwich. Because of that, the directional indicator E (east) or W (west) accompanies the longitude value to show which side of the Prime Meridian the location lies on. This is what makes the answer correct. Longitudes are angular measurements, not distances in kilometers, so B isn’t about the concept. Latitude uses N or S, not longitude, so C isn’t appropriate. And longitudes can be read in different formats (degrees with minutes and seconds, or decimal degrees), so D isn’t a requirement.
