Contours and cross-sections
When a geographer looks at a topographic map they see it in 3D. How do they do that? Basically by being able to read contour lines and draw cross sections in their mind. To do this we need to firstly know how to draw a cross-section to see the landscape in 3D.
Contour lines on a map link points of equal height above sea level. Numbers are used to indicate the height. The numbers on the contour lines are at set intervals
