(5 pts) Construct a topographic profile for the map inFigure 7-E6 from position A to A on the graph paper provided in Figure 7-E6 below. What would happen to the mantle rock at point X if water is added to it? The direction system is useful but imprecise. This is a graded activity, please submit it to your TA at the end of the lab. Step 1. slope of the area you are interested in by subtracting the lowest elevation They are usually mapped with large contour intervals. quickly and accurately across any straight line on a map by following this procedure: a. For a relief map the contour interval is frequently persistent. Sometimes vertical exaggeration is desiredbut, in some cases, you may not want it. What type of plate tectonic boundary is present? They are usually mapped with small contour intervals. A contour interval is a vertical distance or difference in elevation between contour lines. Constructing a topographic map by drawing in contours can be easily done if a person remembers the following rules regarding contour lines: As you draw a contour line on a map you will notice that the elevations on one side of your line will be lower elevations, and elevations on the other side of your line will be higher elevations. Why is mass so important to a stars life?

lines represent lines connecting points of equal elevation above sea level, Contour lines never cross, split, or die off, Contour intervals must be obeyed, therefore the contour lineelevations can only be multiples of the contour interval. All Rights Reserved. For example, if you wanted to do a contour line drawing of a pear, you'd simply draw the outline of the pear, add a stem, and stop there. e. Place the paper In the early days of ribosome research, before the exact role of ribosomes was clear, a researcher made the following observation. On a topographic map, a contour line is a line that depicts ground elevation or depression. contour (X,Y,Z) specifies the x and y coordinates for the values . The number of lines obtained in the above step is taken and added with 1. 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). which means that every place between the marked 6800 foot line and the next Note where this would plot on your graph. It is impossible to determine which location is higher. vertical scales on your topographic profile are not the same. 7. B. Construct flow lines emanating from each point " x " to illustrate the groundwater flow field on the map. The contour lines in this figure are equally spaced. of paper along a line across the area where the profile is to be constructed. Index contours are bold or thicker lines that appear at every fifth contour line. from the highest, and dividing the result by the horizontal distance. (5 pts) 7. To use the same interval for both x and y , specify xyinterval as a two-element vector of the form [min max]. Step 3. CONTOUR/SIGDIG= Sets the number of digits after the decimal point for contour labels; default is 2. Lines or isolines on a map that connect points with the same elevation. Explain why. in the southern portion of the map, the area is underlain by limestone. Use the topographic map (Fig. shows the surface features, or topography of Earth or a certain area. Location B is higher. Contour intervals must be obeyed, therefore the contour line elevations can only be multiples of the contour interval . 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. Contour lines How far is that distance (0.56 miles) in Kms? 1) The contour interval between contour is 40m. For small contour interval, the money required will also more as the field and office work will be more. If the river on this map is 1.93 miles long, what is the gradient for this river? Every sixth contour line has an index contour, which is a bolder or thicker line. The speed the islands are sinking can be estimated by measuring the difference in elevation between two islands and dividing by the difference in their ages (this method assumes the islands were a similar size when they were active). Please use Occams razor as you answer the questions: use the simplest explanation rather than the most complicated explanation to answer the question. Where does it wind up? During the flood event of 9/23/2009, the discharge measured at this gaging station was 21,200 cfs. For the plotting of region, the contour intervals are presumed. A topographic map may or may not include shaded relief to help visualize steep slopes. which of the above geologic events is fifth in the sequence. Table of Contents and lab manual chapter pdf files for download, Overview of Canadian Geology and Mineral and Energy Resources, 4. In most maps, every fifth contour line is an index contour. how old is the sequence of rocks. Based on the assemblage of organisms (A-I) in this sample, what is the age of this rock? Please hand in this lab to your TAs at the end of the lab period. In what direction was the main river flowing? At 500 degrees Celsius, rocks will be buried to about _______ km depth. The headings indicate the direction the Pacific Plate is moving over the hot spot. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. Contour plots with Excel and Matplotlib Select the XYZ data arranged as a single range (Range I4:N8 in the data screenshot below). What is the tolerance for compression test results of concrete, according to the standards? B. Example 2- Draw a profile showing the elevations of the contours. Select the think about the drainage pattern you selected in the previous answer - what does this tell you about the underlying rocks? 8. (1 pt) How much higher is Mount Price than Garibaldi Lake? Creating Contour interval calculator - A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a. . What type of plate tectonic boundary is at this exact location? Closely spaced Salmon River This map is a geologic map of glacial geology in the area, drawn What is the straight line distance between the 8996 b and the 7202 b benchmarks located north and northwest of Phelps Lake? fcontour (f) plots the contour lines of the function z = f (x,y) for constant levels of z over the default interval [-5 5] for x and y. fcontour (f,xyinterval) plots over the specified interval. Q. What type of drainage pattern is present in this area? Hint: draw a simple map or a rough cross-section sketch to help illustrate your logic. 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? If you were standing at the washington monument what direction would you need to walk to get to the U.S. capitol building? If the arrow is pointing toward the contour lines around your location, your location is a higher elevation than the index contour line. 3. which Geologic Law did you use to come to the conclusion you made in the previous question (figure 1.8)? 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. A contour line of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. How and why do we divide stars into groups by mass? Figure 4: Reading Contour Maps . These circular patterns indicate hilltops, like in the diagram below (Figure 3.6). See example under CONTOUR/SPACING below. examine the unconformity shown in figure 1.10. what type of unconformity is this? 3. please add a brief explanation thank you Notice the general shape of this feature. Contour lines rules: 1. Contour interval: The change in elevation from one contour line to the next is always the same within the same map.Many maps have either a 40- or 80-foot contour interval: An 80-foot interval simply means that each contour line is 80 vertical feet away from . Would you expect the gradient of the Missouri River in Nebraska to be greater or less than the gradient that you calculated for the Grape River in Colorado? What approximate discharge would be associated with a 50 year recurrence interval? Please give your answer in grams/milliliter. In which stage of the cycle of stream erosion is this area? Sharp contour points indicate pointed ridges. Based on the drainage pattern type, does the bedrock underlying this area consist of rocks uniformly resistant to erosion or rocks alternating between resistant and non-resistant layers? The difference in elevation between the highest and lowest points in the area on the map. (b) Notice how a mountain saddle, a ridge, a stream, a steep area, and a flat area are shown with contour lines. 9.4) to estimate the elevation of this point as accurately as possible. A slope is easy to recognize in a hilly area. Each contour line shows a different elevation. which of the above geologic events is the second in the sequence, which of the above geologic events is the fifth in the sequence. Examine the path of the river that feeds into and flows out of Quail Lake. For the following exercises, please refer to British Columbia Topographic Map 092G095 of the Mount Garibaldi area in southern BC. From the contour map, a profile can be drawn of the terrain. The zone from 20-2900 Km represents the earth? The height of an object above the surface of the sea. The smallest circles represent the Location B is higher. Q. 1. Given that this portion of the Australian plate moves at a speed of 2.2 inches per year, how old are the snake fossils? What type of tectonic plates are present? In Figure 9.4, what is the elevation of Malcome Bog? This content is subject to copyright. located below the scale. The outside of the fiberglass is maintained at 35C35^{\circ} \mathrm{C}35C, and the total heat flow through the copper-fiberglass combination is 52kW52 \mathrm{~kW}52kW. What can be said about level surfaces of \varphi?
