The figure above illustrates a depression and its representation using contour lines. (The benchmarks have an "x" to locate the spot where the elevation was surveyed). The smallest circles represent the See example under CONTOUR/SPACING below. 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. Digitized contour lines, elevation points and water-courses A contour map consists of contour lines of a given geographical region.

Examine the path of the river that feeds into and flows out of Quail Lake. Betwe View the full answer Transcribed image text: What is the contour interval for the figure below? Remember, because of isostasy the denser plate will be lower than the less dense plate. To illustrate what these hills look like in profile (or, how they would look if you saw them while standing on the ground and looking at them from a distance), you can draw what is known as a topographic profile. Given that this portion of Pangaea broke apart 200,000,000 years ago, calculate how fast South America and Africa are Does your topographic profile show any peaks or valleys? What Is Contour Interval ? : Steps Of Calculating, Characteristics To take the difference, subtract the higher elevated line with the lower elevated line reading. An excerpt from a contour map is shown below. At 2900 Km the S wave velocity falls to 0. A thumbnail version of the map is shown in Figure 7-E7,a larger copy is provided at the back of this lab manual, and your TA will provide you with a full-scale version of the map in lab.

The contour interval (height difference from one contour line to the next) on the 500 mb height map shown above is 3 decameters (abbreviated as 3 dam) or 30 meters (abbreviated as 30 m). First, we must identify the two contours that lie on either side of "P." In some cases the contours that we need are clearly labeled; however, in other instances, you will need to use the contour interval (1,000 feet, in this case) to "count" up or down from a labeled contour. Mountain/Hill Depressions Map Example If you were standing in the middle on the intermost contour line hill "c", your elevation would be. The commonly used contour interval is 20 feet for a 1:24,000 map scale. The selection of the contour interval is decided by the survey leader before the start of the mapping process depending upon the ground factors. Flood stage, or bankfull stage, on Sweetwater Creek occurs at a discharge of ~4,500 cfs. Solved What is the contour interval for the topographic map - Chegg 19. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down. Show that the streamlines of \nabla \varphi are orthogonal to the level surfaces of \varphi. Complete this map by adding in contour lines using a contour interval of 100 m. Draw the contour lines so that they are continuous: they will either continue to the edge of the map or form an enclosed circle. The lowest contour line is at 200m. How far apart are North America and Mainland Asia in cm? -- - . Considering the size of the area to be mapped, contour intervals are assumed. Index contours are prominent or dense lines that bob up at every 5th isometric line. than 6760 feet, but less than 6800 feet. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. They then cross the stream and turn back along the opposite bank of the stream forming a "v". The overview section 7.4.2 provides useful background to help you answer questions 4 & 5. What direction is the North American plate moving in comparison to the Pacific Plate at this location? "Contour" actually means "outline" in French, which is where the name comes from. (1 pt) Garibaldi Creek is located east of Deadmans Lake (Figure 7-E8). The zone from 5100-6400 represents the Earth's ? Refer to the figure below and assume contour interval of 10 feet. pressing down on the middle mouse wheel and moving the mouse forward and Learn more about how Pressbooks supports open publishing practices. It is usually shown in or near the map's legend. According to the geothermal gradient, rocks at 500 degrees Celsius will be buried how deep? The difference between two adjacent contours is called the contour interval, which is 10 ft for the Figure 2-2 example. Contour Lines and Intervals Contour lines connect all the points on a map that have the same elevation and therefore reveal the location of hills, mountains, and valleys. Essentially a topographic profile is a side image of a topographic map, but the image is only a representation of the area shown on the line on the topographic map (line A-B on Figure 3.6). Considering the map, the following steps are used to calculate the contour intervals calculation as follows . The number of contour lines in-between 7000 and 7100 are 4. D) Nothing. An error message is displayed. The height of an object above the surface of the sea. slope percent = rise/run 100. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. Measure the distance using the bar scale between the pole 1400 and 1700 (locations C and F). A contour interval is a vertical distance or a 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 specific contour lines is increasing, the elevation of the area is also increasing. Take that distance and divide it by the speed you calculated in question 3 to estimate when the next supercontinent will form. Use a contour interval of 4 inches. Of the following dated flood events, which one would you expect to happen more often? To show information. d. Is the elevation of waypoint D > or < waypoint C? Information V shaped. 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 contour interval is stated on every topographic map and is usually The even spacing indicates the hill has a uniform slope. 10,500-10000=500 feet Between these two contour lines if we count, there are 10 counter lines. For producing a detailed study of Describe how you decided on an estimated elevation for points A and E. c. Is the elevation of waypoint A > (greater than) or < (less than) waypoint E? In Figure 9.4, what is the elevation of Malcome Bog? In which stage of the cycle of stream erosion is this area? Please enter your email address. A rounded contour indicates a flatter or wider drainage or spur. how old is the sequence of rocks. A standard topographic map uses contour linesto express elevations above sea level and show the shape of the land. lowest line (which is 6760 feet, and not marked) has an elevation equal or greater What important discovery did the researcher miss? Observe the velocities of waves on the graph. contour lines, the steeper the slope. Once your contour lines are drawn, you will notice that you had to draw some lines closer together in some areas and wider apart in other areasand that you may have even enclosed an area by drawing a contour line in a circular pattern. Therefore the topographic profile in Figure 3.6 represents a profile of the map surface (along the A-B line) that has been vertically exaggerated by 10 times (10X). In which zone do the P wave velocities appear to be steadily increasing? 15. The horizontal map distance measures 0.5 inches. Please use Occams razor as you answer the questions: use the simplest explanation rather than the most complicated explanation to answer the question. To calculate this divide the distance (in centimeters) between the two islands by the difference in their ages.
