Question

1. which one is a line of longitude? 30°n 30°s 30°w (circle one)

Explanation:

Longitudes are imaginary lines running from the North Pole to the South Pole, measured in degrees east or west of the Prime Meridian. Latitudes are parallel lines measuring degrees north or south of the Equator. \(30^\circ\text{N}\) and \(30^\circ\text{S}\) are latitudes (north and south of the Equator), while \(30^\circ\text{W}\) is a longitude (west of the Prime Meridian).

Answer:

\(30^\circ\text{W}\)
