D) The landslides are lubricated by marmot number 2, while soil creep is greased by bird droppings, Feedback: As rocks move to streams in many places, such as Pennsylvania, the slow and steady motions are more important than the few dramatic events. Specific places may be dominated by the few, dramatic events, especially in steep mountains, but across the Earth soil creep probably dominates.and marmot number 2 is more slippery so landslides go faster. Points Earned: 1.0/1.0 Correct Answer(s):B9. Soil thickness:A) Reaches a natural balance between production by weathering and loss by mass movement, and humans have not affected that balance.B) Reaches a natural balance between loss by weathering and production by mass movement, and humans have not affected that balance. C) Reaches a natural balance between production by weathering and loss by mass movement, and humans have upset this balance, primarily by increasing weathering so that soils are thickening.D) Reaches a natural balance between production by weathering and loss by mass movement, and humans have upset this balance, primarily by increasing mass movement so that soils are thinning.E) Reaches a natural balance between loss by weathering and production by mass movement, and humans have upset this balance, primarily by increasing weathering so that soils are thickening.Points Earned: 1.0/1.0 Correct Answer(s):D10.
