1. Which is not a possible reason that might have contributed to the development of the slide?
Choose one:
O River erosion may have made the slope unstable.
O Heavy rains may have made the materials heavier and lubricated the slip surface.
O Rock layers were dipping toward the valley, parallel to the slip surface.
O A large housing development was built in the area, making the slope unstable.

A large housing development was built in the area, making the slope unstable

Explanation: A landslide is any geologic process in which gravity of erosion caused by rain causes rock, soil, artificial fill or a combination of soil, rock, or artificial fill to move down a slope. Others that can trigger slides, includes soil erosion whichould be ccaud by rain, the slow weathering of rocks, earthquakes and volcanic. Furthermore, the activity of a large housing development which was built in a particular couldn't have make development of slide possible
