(Answer to the nearest foot.) Transcribed image text: backward or by clicking on the arrows above and below the eye in the upper fault. Contour lines tend to enclose the smallest areas on ridge tops, which are often narrow or very limited in spatial extent. 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). d. Is the elevation of waypoint D > or < waypoint C? Want to create or adapt books like this? Refer to the figure below. The number of lines obtained in the above step is taken and added with 1. This may be easier to determine by examining the tributaries to the main stream. The zone from 2900-5100 represents the Earth's ? The even spacing indicates the hill has a uniform slope. 7. 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. The older unconformity is a Nonconformity, while the younger is a Disconformity. 40 feet. The purpose of this lab is to familiarize students with how to read and use topographic maps. 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). 8,194,375 years to sink. 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.

The peak is normally considered to be located at half the interval distance. Contour Lines and Intervals Contour lines connect all the points on a map that have the same elevation and therefore reveal the location of hills, mountains, and valleys. A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map. It is important for the farmer or irrigator to identify the slopes on the land. We further visualize the globally normalized responses of each convolution filter on the image of grating interval 6 in Figure 5 B. Example 2- Draw a profile showing the elevations of the contours. What type of stream drainage pattern is present on this map? The selection of the contour interval is decided by the survey leader before the start of the mapping process depending upon the ground factors. 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. An error message is displayed. It is south of Mammoth Cave.
