Contour Lines Practice #1

Contour Lines Practice #1Draw in contour lines at the following elevations (all numbers are given in feet above sea level):

250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750

Calculate the gradient from point A to point B

If you cut through the land from C to B, what would the cross section look like? Draw it. (This is called a PROFILE.)

Contour Lines Practice #2Draw 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 YCalculate the gradient from point X to point C

If you cut through the land from C to D, what would the cross section look like? Draw it. (This is called a PROFILE.)
