How to find a slope of a given area in Geography?
Answers
Answer:
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
Answer:
On topographic maps, gradient is usually calculated with reference to two points. A line connecting these two points on the map represents the slope whose gradient is to be determined.
In order to calculate the gradient of a slope, the Vertical Increase (rise), as well as the Horizontal Equivalent (run) of the two points, need to be first determined.
Vertical Increase (also called Vertical Rise) means the difference in elevation between any two points on the map, whereas, Horizontal Equivalent is the actual ground distance between any two points on the map.
Gradient is calculated by simply dividing the Vertical Increase by the Horizontal Equivalent of the two points on a map.
