Which is the correct explanation for 30°S latitude? A. All positions along a circle that runs parallel to the equator and 30°
north of it. B. All positions along a circle that runs parallel to the equator and 30° south of it. C. All positions along a circle that runs perpendicular to the equator and 30° south of it. D. All positions along a circle that runs perpendicular to the equator and 30° north of it.
B. All positions along a circle that run parallel to the equator and 30 degrees south of it. You know this because latitude is horizontal, remember it by thinking latitude/flatitude. Since it is 30 degrees south, it means it will be 30 degrees below the equator.
