Question
**Contour Line Exercise** **Objective:** Draw in contour lines at the given elevations. All numbers are measured in feet above sea level. **Elevations:** - 250 - 300 - 350 - 400 - 450 - 500 - 550 - 600 - 650 - 700 - 750 **Diagram Explanation:** The grid consists of multiple points, each marked with an elevation value (in feet). The task is to draw contour lines that connect points of equal elevation. Here’s a breakdown of the positions on the grid with their respective elevations: - **Row 1:** 350, 400, 400, 350, 350, 300, 250 - **Row 2:** 450, 500, 500, 450, 450, 400, 300 - **Row 3:** 550, 600, 600, 550, 500, 450, 350 - **Row 4:** 600, 650, 650, 600, 550, 500, 400 - **Row 5:** 650, 700, 700, 650, 600, 550, 450 - **Row 6:** 650, 750, 700, 650, 600, 550, 500 - **Row 7:** 600, 650, 650, 600, 550, 500, 450 **Labeled Points:** - **Point A:** Located near two points with elevations of 650 - **Point B:** Placed close to a 300-elevation mark - **Point C:** Situated at a 600-elevation point **Instructions:** Using these points, students should draw smooth, curved lines that connect the dots of equal elevation, creating contour lines across the grid. This exercise aims to help understand topographic maps and how terrain is represented. --- This task primarily serves to improve geographic literacy and spatial visualization skills.
