Here's a breakdown:
* Eluvium: A layer of residual material left behind after weathering and erosion remove finer particles, leaving behind a concentration of coarser materials.
* Weathering: The process of breaking down rocks, soils, and minerals through physical and chemical processes.
* Erosion: The process of moving weathered material from one place to another by wind, water, or ice.
Essentially, eluvium represents the leftovers after wind and water have selectively removed the smaller, lighter particles. This process is often referred to as selective sorting or differential erosion.
