The document provides instructions for two contour line practice exercises. For the first exercise, students are asked to draw contour lines at specific elevation levels and calculate the gradient between points A and B. For the second exercise, students are asked to draw contour lines at different specified elevation levels and calculate the gradients between points X and Y and between points X and C. Students are also asked to draw profile views of the cross sections between points indicated on the two practice maps.

250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750
Calculate the gradient from point A to point B

2. Name:_____________________________________ Period:_________ Date:___________
Contour Lines Practice #2
Draw in contour lines at the following elevations (all numbers are given in feet above sea level):
450, 400, 350, 300, 250, 200, 150, 100, 50
Calculate the gradient from point X to point Y
Calculate the gradient from point X to point C
