Which is NOT a soil particle?

Explanation:
Sand, silt, and clay are defined by size and are individual soil particles. Loam, however, is not a single particle; it’s a soil texture category that describes a balanced mix of those particle sizes, which gives good structure, drainage, and workability. Because the question asks which is not a soil particle, loam fits as the correct choice since it refers to a combination of particles rather than a single particle size. You’ll often see terms like sandy loam or clay loam that describe the overall texture of a soil, not an individual particle.
