When talking about soils, soils are typically divided into various horizons depending on what layers are present. The horizons include in this order:
O Horizon <---- (Organic Horizon) - This is the top soil where plants grow.
A Horizon
B Horizon
C Horizon
Bedrock <---- This is lithified material. This means that there is no longer any lose soil at this point, and it has been turned to rock by pressure of overlaying sediment or other geological processes.
Eluviation occurs in the E Horizon. The E Horizon is also known as the Zone of Leeching. By definition, eluviation is the process of removal of materials from geological or soil horizons. Essentially, this is where most of the weathering occurs in the soil.
Illuviation occurs in the B Horizon. The B Horizon is also known as the Zone of Accumulation. By definition, illuviation is the deposition in an underlying soil layer of colloids, soluble salts, and mineral particles leached out of an overlaying soil layer. In layman's terms, this is where the particles end up in the B Horizon after they are weathered from the A Horizon.

What are the differences between illuviation and elluviation?
Eluviation is the movement of the particles (such as minerals and organic matter) into lower soil horizons. Then Illuviation is the accumulation of those particles in the lower soil horizons.
What are the pedogenic processes?
There are five main pedogenic processes: weathering, translocation, eluviation, illuviation, and organic matter accumulation. Weathering involves the breakdown of rocks and minerals, while translocation moves materials within the soil profile. Eluviation is the process of material moving out of the soil, while illuviation is the accumulation of material within the soil. Lastly, organic matter accumulation refers to the build-up of plant and animal remains in the soil.
What is the difference between eluviation and leaching?
Eluviation is the process by which minerals or fine particles move down through the soil horizon due to the movement of water, while leaching is the process where water moving down through the soil carries away dissolved nutrients or minerals. Eluviation mainly involves physical movement of particles, while leaching involves the chemical removal of substances from the soil.
How is eluviation and illuviation processes are responsible for formation of horozons?
Eluviation is the process of leaching or washing away of minerals and organic matter from the topsoil layer, while illuviation is the accumulation of these materials in lower soil horizons. These processes contribute to the formation of distinct soil horizons as different materials are translocated within the soil profile, resulting in layering and the development of horizons with unique characteristics.
What is the process called when water passes through soil layers drawing elements and particles with it?
This process is called leaching, where water moves through soil, carrying soluble substances such as minerals and nutrients along with it. Leaching can lead to nutrient depletion in the soil and potential contamination of groundwater with pollutants.
How do eluviation and illuviation differ?
in eluviation the mineral particles are generally carried downwards the surface while on contrast illuviation is a leaching process where such minerals are brought to the surface, they are both leaching processes
What are the differences between illuviation and elluviation?
Eluviation is the movement of the particles (such as minerals and organic matter) into lower soil horizons. Then Illuviation is the accumulation of those particles in the lower soil horizons.
How eluviation and illuviation processes are responsible in the formation of different horizons?
Eluviation is the process of removing fine mineral particles from a horizon, while illuviation is the deposition of these particles in a different horizon. As material is leached from one horizon (B horizon) due to water percolation, it gets deposited in a lower horizon (B horizon) where it accumulates. This leads to the formation of distinct soil horizons with varying characteristics based on the movement and accumulation of materials.

What is the colour of eluviation layer?
The color of the eluviation layer can vary depending on the minerals present in the soil, but it is typically lighter in color compared to the underlying layers. This layer is characterized by leaching of clay, minerals, and nutrients, resulting in a loss of color and distinct horizon.
What process of horizon differentiation is illustrated by illuviation?
Illuviation is an accumulation of dissolved or suspended materials in a soil horizon. This process can lead to the formation of distinct soil horizons, especially when certain materials like clays or organic matter accumulate in a specific layer through the downward movement of water.
What is difference between as on and as at?

What is an albeluvisol?
An albeluvisol is a form of soil with a thin, dark surface horizon on a bleached subsurface horizon which tongues into a clay illuviation horizon.
