What is the imaginary line drawn around the Earth that divides the Northern and Southern hemispheres?

• A. Equator
• B. Latitude (Horizontal)
• C. Longitude (Vertical)
• D. Gnomonic Projection (Single Point)

Answer: (A)

The equator is the imaginary line that circles the Earth’s middle at 0 degrees latitude, splitting the globe into Northern and Southern Hemispheres. It serves as the reference for measuring latitude, with lines that run parallel to it extending east and west. Longitude lines run north–south from pole to pole, and a map projection like the gnomonic projection is a way of representing the globe on a plane, not a single line on the Earth. So the equator is the line that best fits the description.
