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. The result is expressed in feet per mile (ft./mi.). This plate boundary isn't as simple as the previous examples, meaning another nearby plate boundary directly influences it. They are usually mapped with large contour intervals. The lowest contour line is at 200m. slope percent = rise/run 100 Expert Answer. 3. In Figure 9.4, what is the elevation of Malcome Bog? They also show elevation. 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. 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. interval. along a line drawn through a portion of a topographic map. Take that distance and divide it by the speed you calculated in question 3 to estimate when the next supercontinent will form. Contour lines never cross. For consistency, assume that elevations between contour lines are 1/2 a contour interval higher than elevation of the lower line. nervous system and circulatory system endocrine and repertory system circulatory and respiratory systems nervous system and endocrine systems .
