Detailed explanation-1: -Slope is generally measured with an instrument called a clinometer. When sighting through a clinometer, the measuring line is placed on the target, and %slope is read from the scale. Both eyes are open, as one eye reads the scale, and the other eye sights on the target (Figure 1.7).

Detailed explanation-2: -Percent of slope is determined by dividing the amount of elevation change by the amount of horizontal distance covered (sometimes referred to as “the rise divided by the run"), and then multiplying the result by 100.

Detailed explanation-3: -An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity’s direction.
