Which of the following is NOT a type of soil mentioned?

• A. Clay
• B. Silt
• C. Angular gravel
• D. Sand

Answer: (B)

The correct choice identifies a type of soil that is often categorized differently within the context of soil types. Silt, while it is a fine-grained material, is indeed considered a type of soil in soil classification systems. This system typically recognizes types of soil based on particle size and composition, including clay, silt, sand, and gravel. Clay is a type of soil that consists of very fine particles and has high water retention capabilities, while sand consists of larger, coarser particles that promote drainage. Angular gravel, although it can be involved in mixtures within various soil profiles, refers more to the physical characteristics of gravel rather than being a soil type per se. When considering standardized categories of soil, all options presented, except for angular gravel, align with common classifications recognized in soil science. Thus, angular gravel is less typically recognized as a specific soil type within the conventional categories.
