Multiple choice: the ratio between resisting forces and driving forces on a slope is/are, can vary with changing precipitation rates b. Perfect storm"), when the jetstream was blocked" and caused a large low-pressure system to stall on the east side of the rockies: snow melt this past spring was delayed. This means there was a lot of water" potential waiting to be unlocked" (melted). Karst is the formation of landscape due to a dissolution of limestone, dolostone, marble, gypsum, or rock salt.

Longshore drift refers to the transportation of sediment along smooth coastlines that extends the beach and can cause barrier beaches.
