Which combination of horizons indicates a glossic horizon?

A glossic horizon is characterized by a specific set of properties, primarily showing evidence of clay illuviation and a distinctive transitional texture and color. This horizon is frequently found between an eluvial (E) horizon, which is lighter in color due to leaching, and a more illuvial (Bt) horizon, which accumulates clay or other materials. In the correct answer, the presence of both E and Bt horizons indicates a clear transition in soil characteristics. The E horizon represents a zone where materials have been leached out, generally making it lighter in color, while the Bt horizon indicates a zone rich in clay that has been deposited through illuviation. The combination of these horizons suggests significant pedogenic processes that define a glossic horizon, including the accumulation of clay and alterations in texture and structure. Understanding the nature and transition between these horizons is essential for identifying a glossic horizon in soil profiles. This signifies the importance of horizon characteristics in soil classification and interpretation, which are crucial skills in soil judging.
