S waves cant travel through liquids and this depth is where the liquid outer core exists. 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. Use the appropriate conversion factor to convert the horizontal map distance to horizontal ground distance. The selection of the contour interval is decided by the survey leader before the start of the mapping process depending upon the ground factors. 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.

Figure 7 . (5 pts) The following topographic map (Map 7-E3) is from a coastal area and features an interesting geological hazard in addition to the ocean. 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. It is impossible to determine which location is higher. Overview section 7.3 provides background information on contour lines to prepare you for these exercises.

On our map, point "P" lies between 3000 feet and 4000 feet contours . Large contour interval is to be used if the time available for the survey work is less. An incredible app, hundreds of features for every kind of math, and the best part is that it shows u what to do on each step and it explains each step, and, very little ads. Transcribed image text: Refer to the hydrologic map in Figure 14.5. Inspect the P wave velocities. What is the tolerance for compression test results of concrete, according to the standards? If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. The given point, 537', therefore, must lie between the 520' and 540' contours (contours aand b). Why is this so? Step 2. What are the different types of handrails used in bridges? The difference between Contour intervals and Horizontal Equivalent are tabulated below: Contour Lines and Its Types, Characteristics and Uses in Surveying.

Pick two contour lines that are next to each other and find the difference in associated numbers. How to Calculate Contour Interval from Maps? For example, if a location point is between the 150 feet and 200 feet contour lines than the elevation is 175 feet (1/2 of 50 feet is 25 feet; 25 feet added to 150=175 feet).

In the early days of ribosome research, before the exact role of ribosomes was clear, a researcher made the following observation. To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: (\(\frac{\frac{1000\;ft}{1\;inch})}{(\frac{100\;ft}{inch}}) = 10\). . Considering the map, the following steps are used to calculate the contour intervals calculation as follows . Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. All melodies have contours. 15. The desired unit is feet. points. If you examine the graph showing the topographic profile in Figure 3.6, can you imagine what would happen to your profile if we changed the spacing for elevations on the y-axis?

Why are colors and symbols used on topographic maps? Q. If the user enters 3.14 in response to the following programming statement, what will be stored in value? Definition of Contour: A contour or a contour line may be defined as the line of intersection of a level surface with the surface of ground. b. 12. Approximately how far did the pole move per day? Also no adds. Contour Lines: Contour lines are used to determine elevations and are lines on a map that are produced from connecting points of equal elevation (elevation refers to height in feet, or meters, above sea level). Please refer to this Saskatoon topographic map to complete the next three questions. Terms and conditions apply. Notice the general shape of this feature. 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. By using a ruler, you can transfer these elevation points from your topographic map straight down onto your graph paper such as shown in Figure 3.6. Explain why. 300 A. Information

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 . How does the direction of motion of the Pacific Plate during the last 1.1 million years differ from direction of movement between 4.7 and 7.2 million years ago? The distance between these areas is ~1.6 miles (measured along the curving distance of the non-magnified stream). Your contour lines will generally fall between the GPS points on your map, so you will need to estimate many of the contour line positions. This plate boundary isn't as simple as the previous examples, meaning another nearby plate boundary directly influences it. Then add 1 to 5 that becomes 6. the final step is the quotient of the difference between 2 index lines (step 2) and the number of lines in between two index lines plus 1 (step 5). To determine the %slope from Point A to Point B, the rise and run must first be determined. on a map that are produced from connecting points of equal elevation (elevation

Practice Questions on Geological Structures, 7. the result from the nearest marked contour line. This is a critical skill to prepare students to learn about more complex geologic maps. A topographic map may or may not include shaded relief to help visualize steep slopes. A contour interval is a vertical distance or difference in elevation between contour lines.

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. Lakes/Ponds. separating in cm/year? They are usually mapped with small contour intervals. Now difference between 7100 and 7000 is 7100 7000 = 100. Lets assume, 7000 and 7100 and calculate the interval between it. Transcribed image text: 6. from the highest, and dividing the result by the horizontal distance. Show your work! The final answer we get after dividing is the contour interval of the specific topographical map. 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. 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. How far apart are North America and Mainland Asia in cm? In the context of evolution through natural selection, explain why multicellular organisms have specialized exchange systems and surfaces. A standard topographic map uses contour linesto express elevations above sea level and show the shape of the land. 10,500-10000=500 feet Between these two contour lines if we count, there are 10 counter lines. Vertical exaggeration is the effect that is created when the horizontal and
