In what general direction is the Pacific Plate moving? trend up valleys and form a "V" or a "U" where they cross Question 20. Vertical 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). Pick two contour lines that are next to each other and find the difference in associated numbers. A slope is the rise or fall of the land surface. 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).

Locations A and B are at the same elevation. It is important for the farmer or irrigator to identify the slopes on the land. 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. Determining If the arrow is pointing toward the contour lines around your location, your location is a higher elevation than the index contour line. Calculate how fast the Hawaiian Islands are sinking, by using the ages and elevations of Maui and Nihoa. 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. For the plotting of region, the contour intervals are presumed. The figure above illustrates various topographic features. Refer to the figure below and assume contour interval of 10 feet. Considering the size of the area to be mapped, contour intervals are assumed. Now count the number of non-index lines contour lines between the 2 index contour lines selected for the contour interval calculating in the 1st step. A contour is a line drawn on a map that joins points of equal height above sea level. 31? Q: Refer to figure 23.5. USask GEOL 121 Lab Final Exam Overview. e.

The rendition of this topography as an isoline (contour) map from an overhead perspective is shown directly below. Be sure to only plot those elevations that are at the intersection of the contour line with line A-B. The difference between two adjacent contours is called the contour interval, which is 10 ft for the Figure 2-2 example. Location A is higher.

During the flood event of 9/23/2009, the discharge measured at this gaging station was 21,200 cfs. You are tasked with creating your own coastal topographic map, so you hike around a coastal area with a GPS receiver (Global Positioning System) and every so often you record your position along with the elevation in metres at that point, which results in the map below (Map 7-E5). Look closely at the topography south of highway, and it changes abruptly. As a rule, hilltops will be slightly rounded to show a slight increase in elevation to represent the crest of the hill, but be careful not to draw the hilltoptoo high on your graph paper. 1.

This means every point on a contour line has the same altitude as that of the assumed intersecting surface. Observe the stream on the Omaha N, Nebraska-Iowa quadrangle. Contour line art is a method of drawing where you draw only the outline of an object, without any shading. The lowest contour line is at 200m. When connecting the points on your graph paper in the area between the two hills in Figure 3.6, you again want to round out the area to represent the base of your valley between the hills, but be careful not to make the valley floor too deep, as according to the topographic map the elevation is below 40ft, but not as low as 30ft. c.

B. 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 .

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. For consistency, assume that elevations between contour lines are 1/2 a contour interval higher than elevation of the lower line. B. Construct flow lines emanating from each point " x " to illustrate the groundwater flow field on the map. V shaped. Contour lines rules: 1. A person standing at point "F" would only be visible to a person standing at: Examine the figure below. it shows natural features such as rivers and lakes. To calculate this divide the distance (in centimeters) between the two islands by the difference in their ages. 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.

If you were standing in the middle on the intermost contour line hill "c", your elevation would be. in the southern portion of the map, the area is underlain by limestone. Vertical exaggeration is the effect that is created when the horizontal and 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. On which date did a flood event have a recurrence interval of 0.5? Contour lines tend to enclose the smallest areas on ridge tops, which are often narrow or very limited in spatial extent. Contour Lines Example 2- Draw a profile showing the elevations of the contours. The equation used is: Tips 2. Description. Figure 4: Reading Contour Maps . 1 ft = 24,000 ft, and 24,000 ft x (\(\frac{1\;km}{3280\;ft}\)) = 7.32 km. Which of the following places represent a Wadati-Benioff zone? Math can be challenging, but with a little practice, it can be easy to clear up math tasks. Among other things, a topographic map can be used to measure the average slope 225 feet; half the contour interval lower than 250 feet. He wants to follow the easiest possible path, which means he needs to find the most gentle slope up the mountain. These marked or labeled lines are known or termed as Index Contour Lines.
