Question

Quizplus · Accepted Answer

The process described is called eluviation, which refers to the downward movement of fine clay particles and dissolved minerals from the E horizon to the B horizon of the soil. Leaching refers to the process of water removing soluble materials from the soil, solifluction is a type of mass wasting that involves slow movement of soil down a slope, and mass wasting refers to the movement of rock and soil downhill under the influence of gravity.
