3. Which factor keeps the rocks from slipping past each other?
A. Arrangement
B. Bending
C. Depth
D. Roughness
Answer:
D. Roughness
Roughness is the factor that helps keep rocks from slipping past each other. When the surfaces of rocks have irregularities, bumps, or rough textures, they interlock with each other, creating frictional resistance that prevents sliding or slipping. This roughness between rock surfaces is an essential component in maintaining stability and preventing movement along fault lines or between rock layers.
