* North Carolina's Location: North Carolina is located in the United States, which is in the Northern Hemisphere.

* Equator: The equator is an imaginary line that circles the Earth at 0 degrees latitude.

* Northern Hemisphere: Locations north of the equator are in the Northern Hemisphere.

* Southern Hemisphere: Locations south of the equator are in the Southern Hemisphere.

Now, let's consider the options:

* Northern Argentina: Argentina is located in the Southern Hemisphere.

* Southern Spain: Spain is located in the Northern Hemisphere.

Therefore, North Carolina is closer to the equator than southern Spain, but farther from the equator than northern Argentina.

Important Note: While North Carolina is closer to the equator than southern Spain, both locations are relatively far from the equator compared to Argentina.
