1. Draw contour lines at 10-meter intervals: Connect points with the same elevation (60, 70, 80, 90, 100, 110, 120) to form continuous lines across the grid.
2. Identify the summit (high point): The highest elevation is 130, located in the lower-right area of the grid.
3. Determine lowest and highest elevations: Lowest is 60; highest is 130.
4. Highlight the steepest gradient: The steepest gradient occurs where contour lines are closest together — between the 120 and 130 contours in the lower-right quadrant.
5. Complete the compass rose: Label directions clockwise from top: North (N), East (E), South (S), West (W).
Parent Tip: Review the logic above to help your child master the concept of contour lines worksheet.
