Toby stays up late night after night in order to ensure he gets the most he can out of his cruise vacation. he tries to sleep during the day, but his cabin is too noisy and he suffers from rem sleep deprivation. what can toby expect to happen during his first several nights back home?

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
