Contour lines that are close together show what type of slope? What type of tectonic plates are present? 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). Contour lines tend to enclose the smallest areas on ridge tops, which are often narrow or very limited in spatial extent.

Now calculate the difference between the two-selected index contour line selected from a map. up or down from the nearest index contour line and multiplying by the contour 200 feet. Apply the principle of conservation of angular momentum to determine the direction a spacecraft will rotate if an internal gyroscope begins to rotate in the counterclockwise direction. Q. Every sixth contour line has an index contour, which is a bolder or thicker line. Complete this map by adding in contour lines using a contour interval of 100 m. Draw the contour lines so that they are continuous: they will either continue to the edge of the map or form an enclosed circle. 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?

The figure above illustrates various topographic features. 2. 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). Considering the size of the area to be mapped, contour intervals are assumed. In which zone do the P wave velocities appear to be steadily increasing?
