If you followed a river from its headwaters downstream to the ocean,you would observe the water clarity decrease because
A)the saltation load would increase.
B)the amount of clay due to weathering increases as does the load and influx of sediment into the river.
C)there is little bed load transport in the mountains.
D)suspended and solution load are greatest in the mountains and decrease as the river enters less steep territory.
E)all material settles out of the flow toward the river mouth and biotic activity increases,increasing the water clarity.

As the river flows downstream, it picks up sediment and particles due to weathering and erosion of the surrounding landscape. This increases the amount of clay and sediment, which decreases the water clarity. Additionally, the water slows down, allowing heavier sediment to settle out, leading to more sediment being deposited on the riverbeds as opposed to flowing in the water.
