Answer to Question 1

F

Answer to Question 2

Initially a thin layer of soil appears on the parent material. As soil ages, biological processes tend to
increase nitrogen content. The passage of time transforms soil so it is less and less like its parent
material. Mature soils are generally productive, but as time passes, weathering, erosion, leaching, and
misuse can make a soil less productive. An old soil can even become the parent material for a new soil.
