Question

what do lines on a contour map indicate?

• degrees north and south of the equator
• elevation above sea level
• degrees east and west of the equator
• where geological features converge

Explanation:

Contour maps are used to represent the elevation (or depth) of the Earth's surface. Lines on a contour map, called contour lines, connect points of equal elevation above (or below) sea level. The other options: "degrees north and south of the equator" refers to latitude, "degrees east and west of the equator" refers to longitude, and "where geological features converge" is not what contour lines indicate. So the correct option is about elevation above sea level.

Answer:

elevation above sea level
