Which of the following has the lowest potential for landslides?

A) Pacific Northwest
B) southern California
C) bluffs along rivers in the central U.S.
D) Florida
E) Appalachian Mountains

Florida has the lowest potential for landslides among the options given. This is because Florida's topography is very flat and it lacks the steep terrain that is typically associated with landslide activity. Additionally, the geological composition of Florida, primarily limestone and sandy soils, does not contribute significantly to landslide conditions compared to the mountainous or hilly terrains found in the other regions listed.
