Final answer:
The equator is at 0 degrees of latitude, which is true, and it divides the Earth into Northern and Southern Hemispheres.
Step-by-step explanation:
True or false: The equator is at 0 degrees of latitude. The correct answer is a) True. The equator is indeed the imaginary line that divides the Earth into the Northern and Southern Hemispheres and is referred to as 0 degrees latitude. It is the largest circle of latitude on Earth.
Other lines of latitude, known as parallels, are numbered from 0 to 90 degrees both north and south of the equator. The Tropic of Cancer, for example, is located at approximately 23.5 degrees north of the equator, reflecting the tilt of the Earth.
