**Basic Topographic Map** Transcription of the text and description of the diagram: ### Text: **Pictured here is a basic topographic map. What is the contour interval of this map?** ### Diagram Description: The diagram depicts a topographic map, which includes the following key features: 1. **Contour Lines:** - These lines represent different elevations on the map. Each line indicates a specific elevation above sea level. The lines are closer together in steeper areas and farther apart in flatter areas. 2. **Elevation Numbers:** - The map has contour lines labeled with elevation numbers such as 80, 100, and 200. These numbers indicate the height (in feet) above sea level for each contour line. 3. **Water Bodies:** - To the right of the map, there is a labeled area marked "Ocean," indicating the presence of an ocean or large body of water adjacent to the land. 4. **Rivers:** - A feature labeled "A1 River" flows from the northwest to the southeast across the map. This river likely influences the contour lines around it, leading to v-shaped contours pointing upstream. 5. **Peaks and Depressions:** - The map shows areas of high elevation, such as peaks labeled with specific elevation marks like "300" and "200". - There are also possible depressions or lower elevation areas implied by compact ring-like contour lines. 6. **Coordinates:** - Specific locations on the map are marked: one with an "X" and another with a "Y" to indicate points of interest or cross-sections. To determine the contour interval (the difference in elevation between consecutive contour lines), look at the labeled elevation on the contour lines and calculate the difference between adjacent lines. For instance, if one line is labeled 200 and the next is 100, the interval is 100 feet.

### Understanding Topographic Maps #### Question: Contour Interval Measurement Study the topographic map provided and determine the contour interval. Select the correct value from the following options: - 10 feet - 20 feet - 50 feet - 100 feet #### Explanation of the Topographic Map: The image displays a section of a topographic map, which depicts the elevation of the terrain using contour lines. - Each contour line represents a specific elevation level. - Elevations are marked at regular intervals to show the height above sea level. - The closer the lines are to each other, the steeper the slope of the terrain. In this specific example: - **Contour Lines**: The map shows various contour lines with elevation markers of 100 and 200 feet. - **Hilltops and Depressions**: Circular contour lines indicate hilltops or depressions. - For example, there is a smaller circular contour labeled "200" feet, suggesting a hilltop. - **Other Features**: The map also contains a river, marked as "Ash River," running diagonally from the bottom-left to the top-right of the image. - **Point "Y"** and other letters might indicate specific locations or reference points for measurements. #### Analysis of the Graph: Reviewing the contour lines and their marked elevations (100 feet and 200 feet), the contour interval can be inferred based on the difference in elevation between successive contour lines. ### Answer Options: 1. **10 feet** 2. **20 feet** 3. **50 feet** 4. **100 feet** After examining the given topographic map, choose the correct contour interval from the options provided. This exercise will help build skills in reading and interpreting topographic maps, which are essential for various fields such as geography, geology, and environmental science.
