The other side is covered with a layer of fiberglass 2.5cm2.5 \mathrm{~cm}2.5cm thick. 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. The elevation at sea level is zero meters. Be sure to only plot those elevations that are at the intersection of the contour line with line A-B. (3 pts) Based on the scale chosen for you for the topography (vertical axis), calculate the amount of vertical exaggeration on the topographic profile you constructed for question 4.

(10 pts) Imagine you are a geologist working for the Geological Survey of Canada. 2. below cuts the mountain at equal intervals of elevation. The contour interval is 20 meters ( Figure 10-2 ), thus each one of the intermediate contour lines crossed to get to point (a) adds 20 meters to the 500-meter index contour line. which Geologic Law did you use to come to the conclusion you made in the previous question? A contour map consists of contour lines of a given geographical region. Usually there are different contour intervals for the different maps.

The run is 1000 feet and the rise in elevation is 120 feet. 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. Make sure to zoom out to get a good view of the relevant features. To take the difference, subtract the higher elevated line with the lower elevated line reading. What is the latitude for the southeast corner of the map? Geology Labs 1-6 (some questions and answers missing) To illustrate what these hills look like in profile (or, how they would look if you saw them while standing on the ground and looking at them from a distance), you can draw what is known as a topographic profile. Map Example on a topographic map base. When you join you get additional benefits. How does the direction of motion of the Pacific Plate during the last 1.1 million years differ from direction of movement between 4.7 and 7.2 million years ago?
