The rate of vertical change per unit distance on the Earth's surface is known as what?

Understanding how steep a surface is comes down to slope. Slope describes the vertical change in elevation (rise) divided by the horizontal distance over which that change occurs (run). It’s the rate at which you gain or lose height as you move along the ground. For example, climbing 50 meters over 500 meters of distance gives a slope of 50/500 = 0.1, or 10%, which corresponds to about 5.7 degrees of incline. Elevation is simply the height above a reference level, not how quickly elevation changes across distance. Tilt refers to a leaning or angle of an object, not a measure of terrain steepness. Gradient is related in broader contexts, but slope is the standard term used for the rate of vertical change per unit distance on the Earth’s surface.
