Q: What is the name of the line used in topographic maps that shows different elevations?


Read this paragraph and choose the correct option from the provided answers:

Mapping is an important part of Earth Science. Topographic maps use a line, called a contour line, to show different elevations on a map. Contour lines show the location of hills, mountains and valleys. A regular road map shows where a road goes. But a road map doesn’t show if the road goes over a mountain pass or through a valley. A topographic map shows you the features the road is going through or past. Let’s look at topographic maps.
