What type of soil is developed on unconsolidated sediment?

The correct choice is based on the understanding that transported soil refers to soil that has been moved from its original location and deposited in a new area. This type of soil is formed on unconsolidated sediment, which means it is made up of loose material that has not yet cemented into solid rock. Transported soils often develop in places where the sediment has been carried by natural processes such as wind, water, or ice before settling in a new location where soil formation begins.

Residual soil, on the other hand, is formed in place from the weathering of the underlying rock, meaning it is developed directly from the parent material without significant movement from its original site. Regolith is a broader term that encompasses the layer of loose, unconsolidated material covering solid rock, but it is not specifically a type of soil. Talus is a specific type of deposit that consists of broken rock fragments that accumulate at the base of cliffs or slopes, and while it can be associated with soil processes, it does not classify as a soil in terms of its development from unconsolidated sediment.
