how would you calculate the gradient between two point marked on a map
Answers
Answer:
Explanation:
Calculate the gradient by subtracting the elevation of the lower contour line on the line you drew from the elevation of the contour line at the other end of the line you drew.
Divide the answer by the distance in feet represented by the line you drew. Multiply that number by 100 to give you the percent slope of the hill. For example, if the number you arrived at was 45. This means that for every 100 feet traveled in the area marked on the map, the elevation changes 45 feet whether going up or down the hill.
Determine the angle of the slope by dividing the change in elevation by length represented by the line you drew. This gives you the tangent value of the slope. Use the arctangent function on your scientific calculator to get the angle of the slope
