Contour lines that are close together show what type of slope? 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? Closer distance indicates steep slope and wider distance gentle slope. Note: elevation is metres above sea level; thus, sea level = ______ m. 2. What type of bedrock is present in this area? Write your estimates for the elevation at each waypoint next to the waypoint. Go back to the location in Google Earth that you examined for question 36 (46 55 25.66 N 152 01 25.17 E). Contour lines Lines or isolines on a map that connect points with the same elevation. contour lines represent steep slopes, conversely, contour lines that are spaced We further visualize the globally normalized responses of each convolution filter on the image of grating interval 6 in Figure 5 B. Please use Occams razor as you answer the questions: use the simplest explanation rather than the most complicated explanation to answer the question. Q. 50m. He wants to follow the easiest possible path, which means he needs to find the most gentle slope up the mountain. The difference in elevation between the highest and lowest points in the area on the map. Creating Given that this portion of the Australian plate moves at a speed of 2.2 inches per year, how old are the snake fossils? To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: (\(\frac{\frac{1000\;ft}{1\;inch})}{(\frac{100\;ft}{inch}}) = 10\). Contour lines are used to show elevation on a topographic 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. What important discovery did the researcher miss?

Make sure to zoom out to get a good view of the relevant features. Inspect the P wave velocities. It is usually shown in or near the map's legend. Melodic contour is the shape and sequence of movements of a melodic line. in Figure 9.4, what is the elevation of the intersection of U.S. Route 1 and Maine Route 6 in Topsfield? In this case, to find out the intermediate points elevation, contour intervals are used. USGS topographic maps also show many other kinds of geographic features including roads, railroads, rivers, streams, lakes, boundaries, place or feature names, mountains, and much more. Determine the height of Mount Price. Write your answer in feet. 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 result is expressed in feet per mile (ft./mi.). A contour line is a line drawn on a topographic map to indicate ground elevation or depression. which of the above geologic events is the second in the sequence, which of the above geologic events is the fifth in the sequence. A red "X" in Figure 9.5 marks a spot on a contour line along the shore of Baskahegan Lake, but the printed DEM doesn't say anything about its elevation. 3. In most maps, every fifth contour line is an index contour. As you can see contour lines with 10 m interval.
