Which of the following is true about the human transported material?

Human transported material refers to soil, sediment, or other materials that have been moved from their original locations, typically through human activities such as construction, landscaping, or agriculture. The correct answer highlights the variability commonly found in this type of material.

Human transported materials often exhibit inconsistent quality and grain size due to their mixed origins. When soil is excavated or moved, it frequently includes a combination of particles from different sources. This means that one shovel full might contain sandy particles, while another could include clay or silt, leading to a heterogeneous mixture. Additionally, human activities may introduce contamination or organic materials that further contribute to the inconsistency in quality.

This contrasts with materials found in natural settings, which tend to be more uniform and better sorted due to natural processes like water or wind transport, where sorting occurs based on size and density. As a result, human transported materials generally lack the consistency found in naturally occurring deposits. The presence of varying sizes and types of particles can also affect other properties of the material, such as drainage and compaction characteristics.
