The Northern Hemisphere is located north of which imaginary circle?

• A. Equator
• B. Prime Meridian
• C. Latitude line
• D. Longitude line

Answer: (A)

The key idea is how Earth is divided into hemispheres. The equator is the imaginary circle at 0 degrees latitude that goes around the middle of the planet and separates the northern half from the southern half. So everything north of the equator lies in the Northern Hemisphere. The Prime Meridian is about 0 degrees longitude and splits east and west, not north and south. A latitude line is any circle parallel to the equator at a specific latitude, and longitude lines run from pole to pole, measuring east-west position. Hence, the Northern Hemisphere sits north of the equator.
