Responses
A. Weathering occurs due to tectonic activity, while erosion is caused by weather patterns.
B. Weathering involves the transportation of weathered materials, while erosion involves the physical breakdown of rocks.
C. Weathering involves the physical breakdown of rocks, while erosion involves the transportation of weathered materials.
D. Weathering and erosion are the same processes.
C. Weathering involves the physical breakdown of rocks, while erosion involves the transportation of weathered materials.

It is the rainy season! Rivers are more muddy-looking during storms. All BUT ONE statement helps to explain this occurrence.(1 point)
Responses
A. Fast-moving water can pick up, suspend, and move larger particles more easily than slow-moving waters.
B. A swiftly moving river will have more water.
C. Sediment builds up at on the river bottom and the river looks muddy.
D. During a storm, a river is carrying a lot more sediment than during a low-flow period.
B. A swiftly moving river will have more water.
Students performed an experiment to observe how water interacts with the rock cycle. The diagram here shows the before, during, and after images for their experiment. What hypothesis do the results support in this experiment?
A. As water flows, it moves larger rocks more slowly than smaller ones.
B. As water freezes, its expansion causes cracks in rocks to expand as well, contributing to weathering.
C. Mechanical breakdown of rock is easier to observe than chemical breakdown of rock.
D. Chemical properties of the water caused the rock to disintegrate, contributing to erosion.
