Question

Which of the following mass movements is most likely to occur in a geologic setting where the rock strata are inclined?

1) Rockfall
2) Landslide
3) Creep
4) Slump

Answer 1

In a geologic setting with inclined rock strata, a landslide is the most likely mass movement to occur due to factors such as erosion, saturation, and seismic activity contributing to slope instability and failure.

Step-by-step explanation:

The mass movement most likely to occur in a geologic setting where the rock strata are inclined is a landslide. In areas with inclined strata, the layers of rock or soil may become weakened through processes like erosion, water saturation from heavy rains or snowmelt, or seismic activity. When these layers are over-steepened, the risk of a landslide is increased as gravity acts more directly on the slope, making it prone to failure. Other factors such as volcanic eruptions and excess weight from accumulated material can also contribute to slope instability, potentially triggering landslides.
