Question

Which of the following locations would have the finest sedimentary particles?

outside bend of a river
source of a river
inside bend of a river
mouth of a river

Answer 1

The location that would have the finest sedimentary particles among the options provided is the **mouth of a river**. At the mouth, where the river flows into a larger body of water (such as an ocean or lake), the flow velocity typically decreases significantly. This slowdown allows finer particles, such as silt and clay, to settle out of the water column, resulting in finer sediments being deposited. In contrast, the outside bend of a river experiences faster flow and can carry coarser sediments, while the source of a river is often rocky and not conducive to fine particle deposition. The inside bend of a river also tends to deposit coarser materials due to the point bar formation, where sediment accumulates.
