Answer:
Erosion
Explanation:
Building a house on a cliff is a very trick thing. The cliffs usually are not composed of hard rocks, but instead are usually composed of sedimentary rocks which are much softer and less stable on the long run. The cliffs are also exposed to heavy erosion, in the lower parts because of the waves, in the higher parts because of the winds. The erosion makes the cliffs slowly fall apart, and occasionally even crumble down, so a builder that would build a house on a cliff should be wary of all these things and construct the house where it is the safest for the long run.

erosion and land water cause the ground to do either two things.
erosion causes the soil on top to be picked up by moving water or pounding and splashing water from the rain. this soil is usually moved to the bottom or to the lowest level around it.
land water, which causes the soil under to become softer and is able to become more and more compact and able to turn to petrified soil or even rock.
