As contour intervals are for the calculation of vertical elevation of an area, same way to calculate the horizontal distance it is termed as Horizontal Equivalent. a stream. Given that this portion of the Australian plate moves at a speed of 2.2 inches per year, how old are the snake fossils? They also show elevation. Mathematically, a contour line is a curve in two dimensions on which the value of a function f (x, y) is a constant. The final answer we get after dividing is the contour interval of the specific topographical map. To calculate this divide the distance (in centimeters) between the two islands by the difference in their ages. Figure 4: Reading Contour Maps . In Figure 9.7, what is the elevation of the lowest point in the crater? The peak is normally considered to be located at half the interval distance.
