Is rendzina soil a podsol or a brown earth soil?
The main difference between rendzina and podsol is B horizon. There is no B horizon in rendzina podsol which is termed as illuvial zone where leaching is most effective. Brown earth soil usually occurs when soil pore space are filled with air. This depends on rainfall , in podsol rainfall is usually higher and so water moves downwards filling the pores with water. Rendzina horizon has more air spaces and so the color is usually brown.
Where is most organic material found in the soil?
In the uppermost six inches of soil is where most organic material is found. That's also where many plant roots are located. It's precisely because of the nearness to the surface and the availability of air, moisture, and nutrients that many roots tend to be located in those upper six inches. So it's a zone of high competition between soil food web critters and plants.

Where in the soil profile is solid rock being weathered?
Solid rock is being weathered at the bedrock layer, which is the deepest layer of the soil profile. Weathering processes like physical breakage and chemical decomposition act on the bedrock to gradually break it down into smaller particles, contributing to soil formation.
Is horizon a on top or is horizon b on top?
The terms "horizon a" and "horizon b" typically refer to layers in a soil profile or stratigraphic sequence, with "horizon a" often representing the uppermost layer, such as topsoil, while "horizon b" is usually a deeper layer beneath it. Therefore, horizon a is generally considered to be on top of horizon b. However, the specific context may vary, so it's essential to clarify the definitions being used in each case.
