What characteristic describes a Moderately coarse B horizon?

• A. Sticks a little and makes a long ribbon
• B. Hand not dirty and sticks a little
• C. Very sticky and hard to make a ribbon
• D. Rocks and gravel pieces

Answer: (B)

A Moderately coarse B horizon is characterized by a texture that allows the soil to be somewhat cohesive, but not excessively so. The option indicating that it is "hand not dirty and sticks a little" reflects the properties of a moderately coarse soil, where the soil particles, while having some adherence to each other, do not create a muddy or overly sticky feel. This level of texture allows for some degree of manipulation without excessive mess. The other options describe either more extreme characteristics of soil texture, such as very sticky or difficult-to-handle soils, or soils that contain large fragments. Therefore, the chosen answer appropriately captures the essence of a moderately coarse B horizon, indicative of its balance between cohesion and manageability.
