![]() ![]() You know that you're looking at a valley bottom when contour lines are V or U-shaped. The rule of V and U-shaped valleys: Valleys are elongated low-lying depressions usually with a river flowing through it. What is the total relief (highest elevation minus lowest elevation) of this feature? Include units.ġ0. ![]() What is the name of the feature shown in the topographic map below? 50 40 30 20 10 9. Draw your profile on the graph included below. Using the same map, construct a cross section (also called a topographic profile) along line X-Y. What is the contour interval of the map shown below? 50 20 30 40 (Elevations shown in Feet) 8.

In each map, the contour intervals is specified on the right-hand side.Ĭounters are usually programmed with fixed intervals that determine how long the counter will count before it signals. For the plotting of region, the contour intervals are assumed. Usually, there are totally different contour intervals for various maps. What is a contour interval on a topographical map?Ī contour interval is a vertical distance or a difference in elevation between two contour lines in a topographic map. Divide that elevation difference by the number of contour intervals between index lines (usually five). To calculate contour intervals, find the elevation difference between two adjacent index lines or index contours. What is contour interval explain the factors affecting contour interval?Ī contour interval is a vertical distance or difference in elevation between contour lines in a topographic map, index contour lines are bold or thick lines that appear on every fifth contour line and if the number associated with a particular contour lines are increasing, elevation increases in the area as well. ![]() The contour interval on a map also depends upon the purpose for which the map is to be utilized. The contour interval is kept inversely proportional to the scale of the map. What are the factors of contour interval? What is the definition of index contour in science?Ī contour line shown on a map in a distinctive manner for ease of identification, being printed more heavily than other contour lines and generally labeled with a value (such as figure of elevation) along its course. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval.
