What do close contour lines represent on a map? how old is the sequence of rocks. Step 3. What would cause two separate samples of pure water to have slightly different pH\mathrm{pH}pH values? It is impossible to determine which location is higher. A contour map consists of contour lines of a given geographical region. When we hold a ruler to the y-axis of the topographic profile in Figure 3.6, we see that 0.5 inches = 50ft, which means 1 inch = 100ft on the vertical scale. How were you able to come to this conclusion? do not cross each other, divide or split. Gradient: Stream gradient can also be determined from a topographic
index contour lines are generally darker and are marked with their elevations. (The benchmarks have an "x" to locate the spot where the elevation was surveyed). 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). Explain why. If so, what are the corresponding highest and lowest elevations? 8. Note: The intervals are increasing, therefore, the contours indicate a hill.

Contour lines make a v pattern as they cross streams and rivers, and the v always points towards the upstream direction. Taking the area to be mapped, contour intervals are considered. Please enter your email address. Figure 2 is the cross section along line AB. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. You want to have the y-axis of the graph paper represent the elevations of the contour lines that intersect your drawn line (line A-B in this case). f.

Figure out math tasks Determine Contour Interval and Contour Line Values. Measure the gradient to the index contour past the word Creek (the last contour before it reaches Arkansas River). This plate boundary isn't as simple as the previous examples, meaning another nearby plate boundary directly influences it. Using a contour interval of 40 m, label the elevation of every contour line on the map below. What is the term for the geologic feature called Carter Lake?

What is the change in elevation across each contour interval (i.e., between successive "regular" contours) on this map? Assume value is an integer variable. 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. These features you are seeing are linear valleys. When you join you get additional benefits. 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 figure above illustrates a depression and its representation using contour lines. Then, find the difference in elevation between the two points. (5 pts) Figure 7-E4 shows five waypoints (A, B, C, D, and E) on a topographic map. contour (X,Y,Z) specifies the x and y coordinates for the values . The equation used is: Tips
In most maps, every fifth contour line is an index contour. It is thought to have formed by the runoff of either precipitation or groundwater. How big is the base (area) of the washington monument in sq feet? Because the stream flows south, contour a, which lies downstream of contour b, must be the lower of the two. 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?

(2 pts) What is the gradient between Garibaldi Lake and Mount Price? To calculate this divide the distance (in centimeters) between the two islands by the difference in their ages. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing. Contour intervals must be obeyed, therefore the contour line elevations can only be multiples of the contour interval . How far (in Km) did the pole move in one year during this time period? What are the different types of handrails used in bridges? To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: (\(\frac{\frac{1000\;ft}{1\;inch})}{(\frac{100\;ft}{inch}}) = 10\).

The given point, 537', therefore, must lie between the 520' and 540' contours (contours aand b). Sharp contour points indicate pointed ridges. On a topographic map, a contour line is a line that depicts ground elevation or depression. 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. How far did the pole move in meters in one year during this time period? Q. Which gas station is the most likely source of the gasoline leak? 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. What is the contour interval on a map based on?

Upon adding divalent ions, she could regain 70S70 S70S particles, but never 1005 or 1305 particles. Q. Based on the map below, which location has a greater elevation, A or B? Use a contour interval of 4 inches. We further visualize the globally normalized responses of each convolution filter on the image of grating interval 6 in Figure 5 B. The difference in elevation between one contour line and the next. For the plotting of region, the contour intervals are presumed. The even spacing indicates the hill has a uniform slope.

Contour lines never cross. slope percent = (120ft / 1000ft) 100 = 12% Measure the distance, using bar scale, between the pole in 1400 and 1500 (locations C and D). 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 . For consistency, assume that elevations between contour lines are 1/2 a contour interval higher than elevation of the lower line. You will receive a link and will create a new password via email. contour lines, the steeper the slope. (b) Why do you think reassociation to 1005 and 130 S particles did not work? The purpose of this lab is to familiarize students with how to read and use topographic maps. 6. D) Nothing. Using a contour interval of 40 m, label the elevation of every contour line on the map below. USask GEOL 121 Lab Final Exam Overview. Locations A and B are at the same elevation. 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.
