Gradient and Rate of Change. Gradient Review. How steep or gentle a slope is Lines close together means steep gradient (rapid changes). Lines far apart means gentle gradient. Gradient = Change in field value Change in distance See reference table cover & remember your units!.

Gradient Review • How steep or gentle a slope is • Lines close together means steep gradient (rapid changes) Lines far apart means gentle gradient
Gradient= Change in field value Change in distance See reference table cover & remember your units!
Change in field value Gradient = Distance 200m-50m Gradient = 6 miles 150 m Gradient = 6 miles Gradient = 25 m/mile
Rate of change • How fast a field changes • Similar to gradient, but is change in field relative to time and not distance Rate of change= Change in field value Time
It took 2 hours for a group to walk from C to D. At what rate did they change elevation? Change in field value Rate of change = Time 200m-50m 150 m Rate of change= Rate of change= 2 hours 2 hours Rate of change = 75 m/hr
