Contour Lines and Slope Analysis AP Human Geography Quiz

🌍 Quick Study Guide

• ⛰️ Contour lines connect points of equal elevation.
• 📈 Closely spaced contour lines indicate a steep slope.
• 📉 Widely spaced contour lines indicate a gentle slope.
• 🏞️ Concentric circles of contour lines usually indicate a hill or mountain.
• 🌊 Depressions (like craters) are indicated by contour lines with hachure marks (short lines pointing downhill) inside the circle.
• 🧭 Slope is calculated as the change in elevation divided by the distance. Slope = $\frac{Rise}{Run}$
• 🗺️ Topographic maps use contour lines to represent the three-dimensional shape of the land on a two-dimensional surface.
