Question

Quizplus · Accepted Answer

A contour is a line that shows points of equal elevation.
Key Takeaway: A contour line, also known as an isoline, joins points of equal elevation above a given level (like the sea level). Contour lines describe the intersection of a surface with one or more horizontal planes. In other words, all other relative spaces are described in relationship to that line. An example would be the sea level when we say that other places are so many feet above or below the sea level.
