Which information is not typically found in a soil profile?

• A. Phases of the moon
• B. Texture
• C. Color
• D. Depth

Answer: (A)

A soil profile is a vertical view of soil layers from the surface down to the parent material, showing horizons and their properties such as texture, color, and depth. Phases of the moon aren’t part of what a soil profile documents because they don’t relate to the soil’s physical or developmental characteristics. Texture refers to the relative amounts of sand, silt, and clay, which affects water movement and retention. Color reflects organic matter content and oxidation conditions, giving clues about drainage and composition. Depth indicates how thick the horizons are and how far soil development extends. Since lunar phases don’t influence these soil properties in a way that’s recorded in a profile, information about the moon phase isn’t typically found there.
