Answer: Northern Argentina is closer to the equator than Spain.
Explanation: The equator is an imaginary line drawn around the middle of a planet(In this case Earth) or a celestial body. It is assumed to be halfway between the North Pole and the South Pole, at a latitude of 0°.
The equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
In this case Northern Argentina is closer to the 0°(equator) than Spain which is located close to the North Pole, far away from the equator.
