How is eluviation and illuviation processes are responsible for formation of horozons?
Based of the soil horizons OAEBCR :The Eluviation process is a chemical process that forms Layer E and involves the weathering down of mineral and organic matter from the soil horizon layer A and depositing the chemically weathered matter in soil horizon layer E. This material is short lived and weathers quickly. This weathered material forms the horizon layer B (Zone of Illuviation). Illuviation is a process that functions in a vertical and gravitational pull process resulting in soil horizon layer B. This material is typically old soil and usually clays (with Fe and Al oxide coating).
What is the process called when water passes through soil layers drawing elements and particles with it?
Leaching is the removal of substances by percolating water.The movement of dissolved substances or particles into a horizon is called illuviation. The movement of dissolved substances or particles out of a horizon is called eluviation.
What is the difference between illuviation and eluviation?
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 is the process by which an originally homogeneous Earth developed a dense core and a light crust?
The process is called differentiation
How do you make a soil profile?
Soil Profile refers to the layers of soil; horizon A, B, and C. If you're wondering what horizon A is, here's your answer: horizon A refers to the upper layer of soil, nearest the surface. It is commonly known as topsoil. In the woods or other areas that have not been plowed or tilled, this layer would probably include organic litter, such as fallen leaves and twigs . The litter helps prevent erosion, holds moisture, and decays to form a very rich soil known as humus. Horizon A provides plants with nutrients they need for a great life. The layer below horizon A, of course, has to be horizon B. Litter is not present in horizon B and therefore there is much less humus. Horizon B does contain some elements from horizon A because of the process of leaching. Leaching resembles what happens in a coffee pot as the water drips through the coffee grounds. Leaching may also bring some minerals from horizon B down to horizon C. If horizon B is below horizon A, then horizon C must be below horizon B. Horizon C consists mostly of weatherized big rocks. This solid rock, as you discovered inSoil Formation, gave rise to the horizons above it.

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
The process which cells develop uniquie characteristics in structure and function is called?
Differentiation part of the Gastrulation process
What is it called when a stem cell becomes specific type of cell?
differentiation.
The process of differentiation produces what?
specialized cells
What is a process by which cells change in structure?
What is the change in structure and function of a cell as it matures: specialization Answer: differentiation
What process is illustrated by this animation?
evaporation
What does mapping refer to in the process of cell differentiation?
In cell differentiation: Mapping refers to the different phases, distinguishing between them and analyzing them.
What is the process by which cells develop differences in structure and function?
It's called differentiation and it's not yet as well understood as we'd like it to be. Some genes get activated and others get deactivated during mitosis. The process appears to be mediated by peptide signals from within the cell and from neighboring cells.
What is The Marketing Segmentation and Positioning Process?
segmentation, differentiation, positioning
