Question

Quizplus · Accepted Answer

Alluvium is a term used to describe sediment deposited by streams, so option A is the correct answer. An alluvial terrace (option B) is a flat area adjacent to a stream, which has been formed by sediment deposition over thousands of years. An unpaired terrace (option C) is the result of uplift and erosion, rather than sediment deposition. A talus fan (option D) is formed at the base of a slope, composed of rock debris, while colluvium (option E) is made up of sediment that has accumulated at the bottom of a slope.
