Question

which of the following effects does weathering have on earths surface?
a. weathering causes mudslides and landslides.
b. weathering causes the breaking down of rocks.
c. weathering causes the formation of a sand dune.
d. weathering causes the movement of sediment down a river.

Explanation:

Weathering is the process of breaking down rocks into smaller pieces. Mudslides and landslides are related to mass - movement (erosion and gravity), not just weathering. The formation of a sand dune is mainly due to wind - driven sediment deposition (erosion and deposition). The movement of sediment down a river is related to water - driven erosion and transportation.

Answer:

B. Weathering causes the breaking down of rocks.
