Soil erosion is one of the most serious soil-degrading processes. Each year tons of soil erode from
cropland, pastures, forests, and other places. The amount of erosion varies dramatically among various
land-use types. The figure above shows the effects of different agricultural practices and slopes on
annual erosion rates.
(a) Refer to the graph above for the following.
(1) Identify the scientific question that resulted in the data presented in the graph.
(H) Identify the agricultural practice that could be used on a 15% slope without leading to a
higher than tolerable loss of soil
