a sheet of paper and stand it up on your desk like a tent.
Using the principles of contouring, draw the contour lines that would
appear on it. Then, draw the map that would illustrate those
contours. Flip the paper upside down so it forms a "V".
Draw the equal
elevation contours and map.
Start with a fresh piece of paper, crease it, and prop one end of it on a book so it forms a tilted tent. Draw the topographic contours and map. Finally, flip the paper upside down so it forms a "V", tilt it, and draw the contours and map.
