After the arrival of European settlers on the Lower Mississippi, residents constructed
levees along the river to protect their homes and farmlands from periodic flooding as
well as to keep the channel open to navigation. Now, residents have problems with land
subsidence, wave erosion, land fertility, and increased severity of floods and hurricanes,
particularly in the Delta area of southern Louisiana. Why would the construction of
artificial levees result in these problems?

soils.
D) No, once a soil is created in a location, it cannot be weathered and eroded.
