What is the latitude of the equator?

• A. 0 degrees
• B. 23.5 degrees N
• C. 90 degrees N
• D. 66.5 degrees S

Answer: (A)

The latitude of the equator is defined as 0 degrees. This is the reference point from which all other latitudes are measured, with latitudes increasing up to 90 degrees towards the North Pole and decreasing down to 90 degrees towards the South Pole. The equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres, and it is the only latitude that is considered to be at zero degrees.

The other options represent different significant latitudes: 23.5 degrees N is the latitude of the Tropic of Cancer, 90 degrees N is the latitude of the North Pole, and 66.5 degrees S marks the Arctic Circle in the Southern Hemisphere. This context helps clarify the unique status of the equator at 0 degrees.
