The gradient of a stream can be defined as the drop in stream elevation along its course and is expressed in meters per kilometer or in feet per mile. A related concept is the slope of a stream, which is defined as the vertical drop of a stream divided by the horizontal distance over which the drop takes place. What is the slope of stream A that drops 264 ft/mi? What is the slope of stream B that drops 200 rn/km (1 ml = 5280 ft; 1 km 1000 m)?
