<p> Name: Date: Block:</p><p>Exploring Topography </p><p>Directions: Go to www.classzone.com. Select High School Science, VA, “GO”. Click the “Go to the Exploring Earth Website”. Enter, in the top left, the code ES0307.</p><p>1. Write a detailed description of the topography you observe during the flyby. (Page 1)</p><p>2. Compare the topographic map to the photo. Describe the pattern of the contour lines around features on the photo. (Page 2)</p><p>3. Click the arrows to move the water up and down. Which part of the land was the last to flood? (Page 3)</p><p>4. Read the information on the page. How do you calculate the elevation of any contour line? (Page 4)</p><p>5. What is the elevation of points labeled A, B, and C? (Page 4)</p><p>6. Describe the overall shape of the land. (Page 5)</p><p>7. What do closely spaced lines indicate about the shape of a feature? (Page 5)</p><p>8. What is the pattern of the contour lines around a simple hill? (Page 6)</p><p>9. Make a sketch of the pattern of the contour lines moving up the valley. Draw an arrow to indicate the direction water would flow. (Page 7)</p><p>10. What landform does the model show? (Page 8)</p><p>11. What do hachures on contour lines indicate? (Page 8)</p><p>12. Describe the structure inside the blue box. (Page 9)</p><p>13. Which point is at a higher elevation, A or B? Explain how you know. (Page 10)</p><p>14. Why is the contour interval on this map 200 feet and not 10 feet? (Page 10) Part 2: Examining Real Topographic Maps</p><p>Use the maps from 100 Topographic Maps to answer the following questions.</p><p>1. Page 89- In what direction does the stream near Dripping Spring flow? How do you know? </p><p>2. Page 89- Look at area 4C on the map. Describe the features or symbols you see in this section. </p><p>3. Page 53- Which side of Lookout Mountain is the steepest? How do you know? </p><p>4. Page 53- What does the blue area in area 1E represent?</p><p>5. Page 48- What do the black * near Lobster Rocks represent?</p><p>6. Page 43- How many buildings are on the northeast side of South Pass near Port Eads?</p><p>Part 3: Constructing a Topographic Profile</p><p>Directions: Draw a topographic profile for maps 1 and 2. Answer the questions for map 3.</p><p>Steps: 1. Line your piece of scrap paper along the line AB. 2. Mark on your scrap paper the point at which a contour line intersects with your paper. 3. Next to each point on your scrap paper write the correct elevation by looking at the topographic map.</p><p>4. On a piece of notebook paper, draw a horizontal line and create a scale going up the left side.</p><p>5. Line your scrap paper up to the horizontal line and move each point from the scrap paper up the scale and plot.</p><p>6. Connect your points. This is a profile of line AB. Map #1 (Draw Profile)</p><p>Map #2 (Draw Profile) Map#3 (Answer questions based on map)</p><p>1. Which of the following is the correct profile for line AB? </p>
