This document contains instructions and questions for a practice worksheet involving interpreting an elevation contour map. Students are asked to measure distances between points on the map in centimeters and convert to miles using the provided scale. They also determine elevations at different points and calculate elevation gradients between points by dividing the elevation difference by the distance between points. Students are asked to draw elevation profiles across two lines on the map.
