Concept:The Equator is the line of latitude that splits the Earth into two equal halves.
Explanation:The Equator is located at
0∘ latitude, exactly midway between the North Pole and the South Pole.
It is the only parallel of latitude that divides the Earth into two equal halves.
These two halves are called the Northern Hemisphere and the Southern Hemisphere.
The Tropic of Cancer at
23.5∘N lies entirely within the Northern Hemisphere, so it cannot divide the Earth into two hemispheres.
The Tropic of Capricorn at
23.5∘S and the Antarctic Circle at
66.5∘S both lie within the Southern Hemisphere, so they also cannot serve as dividing lines.
Only the Equator, at
0∘, creates the major global division between north and south.
Answer:Option B: The Equator.
