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 various processes of soil formation?
1. Humification. 2. Mineralization. 3. Leaching. 4. Illuviation. 5. Elluviation.
What is elluviation?
Refers to the downward movement or loss of dissolved or suspended material within soil by leaching (i.e. salts, nutrients and silicate clays. elluviation leaves the topsoil or A horizon and creates the E horizon. Materials accumulate in the zone of illuviation or accumulation in the B horizon underneath the E horizon.
What are the different layers in a typical soil profile?
1. O - Layers/horizon (organic layer, containing humus). 2. A - Layer/horizon (top soil). 3. E - Layer/horizon (zone of elluviation). 4. B - Layer/horizon (sub-soil). 5. C - Layer/horizon (zone of illuviation/accumulation). 6. D - Layer/horizon (parent materials/bed rocks).
What is the differences between rain and rainfall?
There is no difference between rain and rainfall
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).

Which layer in a soil profile contains the most organic matter?
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.
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 within group and between group differences?
Within-group differences refer to variations that exist among individuals or data points within the same group or category. This can include differences in characteristics, behaviors, or outcomes within the group. Between-group differences refer to variations that exist between different groups or categories. This can include differences in averages, distributions, or patterns observed when comparing multiple groups.

What are the Differences between Hausa and Ibo culture?
Hausa culture is predominantly found in northern Nigeria while Ibo (Igbo) culture is mainly in the southeastern region. Hausa society is traditionally organized around Islamic principles while Igbo culture is more diverse in its religious practices. Additionally, the languages, traditional attire, and food differ between the two cultures.
