What type of process is going on at this location? You can find out exactly how steep the Lay a strip Zoom out and examine the surrounding area, what geological hazards are likely in the area? maps also have a vertical scale to allow the determination of a point in three It is important for the farmer or irrigator to identify the slopes on the land. A higher contour interval is used for a large area and small contour interval for small area. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. To solve a math problem, you need to figure out what information you have. Determine the direction of the slope (aspect) from the index contour line to your location by drawing an arrow from the index contour line to the next higher elevation contour line. The figure above illustrates a depression and its representation using contour lines. Put simply, contour lines mark points of equal elevation on a map. 2. On large-scale maps with a lot of topographical detail, the contour interval is usually smaller, while on small-scale maps with less detail, the contour interval is larger.

Which of the following lakes has a shoreline that is most likely at an elevation between 10,240 and 10,320 feet above sea level? For this computation, the rise, or vertical ground distance, and run, or horizontal ground distance, are needed. Which of the following statements about them is true? Mark The contour interval is 20'. Write your answer in feet. The number of contour lines in-between 7000 and 7100 are 4. View the full answer. Start climbing from the foot of a hill toward the top, this is called a rising slope (see Fig. A. Contour the water table data, using a contour interval of 10ft. A contour interval is a vertical distance or the difference in the elevation between the two contour lines in a topographical map. Sensor stability as characterized through mean absolute differences (MARD) on every study day including only sensors inserted on study day 1. For small contour interval, the money required will also more as the field and office work will be more. a view of the landscape as seen from above. available from: Open Geosciences. The difference between Contour intervals and Horizontal Equivalent are tabulated below: Contour Lines and Its Types, Characteristics and Uses in Surveying. WORKED-OUT CONTOUR MAP PROBLEM - City University Of New York The Wadati-Benioff zone is associated with which type of plate boundary? What do close contour lines represent on a map? Using the speed you calculated in the previous question (and ignoring possible changes in sea level), when will the Big Island of Hawaii sink below the surface of the ocean? To avoid having your profile distorted so that it accurately conveys what the surface of the Earth really looks like in profile, you will want both the vertical and horizontal scales to match. Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e.g., in search results, to enrich docs, and more. Measure in centimeters the distance (Map Length) between the two points you recorded in the previous question.
