Question

what are contour and how do they help in reading topo sheets​

Answer 1

Answer:

What is a contour?

An imaginary line that connects points of equal value. A contour map typically shows multiple contours such as elevation or temperature contours. Explanation:-. the scale of the map and the contour interval gives the extent and general landform of the area . to understand the map , the legends /key are very useful because they depict various features given in the map .

Answer 2

Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. They're useful because they illustrate the shape of the land surface — its topography — on the map.
