B)liquefaction
C)transformation
D)illuviation

Question

Quizplus · Accepted Answer

Illuviation is the process of accumulating materials from above, as water percolates through the soil profile and carries minerals and nutrients from the surface downwards into the underlying horizons. This is often seen in soil profiles with clear layering, where minerals and organic matter accumulate in distinct horizons based on their density and ability to move through the soil. Eluviation, on the other hand, is the process of removing materials from the soil profile through leaching or erosion, while liquefaction refers to the transformation of soil from a solid to a liquid state (usually due to seismic activity). Transformation is a more general term that can refer to any change in the structure or composition of soil, including processes related to weathering, biogeochemical cycling, or disturbance.
