WebMar 13, 2024 · This process is called leaching. Under normal circumstances, minor levels of leaching occur with typical rainfall, and the breakdown of organic materials on the surface resupplies the soil. In the case of excessive rainfall or irrigation, the effects of soil leaching can be more dramatic. Webleaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer. The rate of leaching increases with the …

Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. They are typically classified as oxisols (USDA soil taxonomy) or ferralsols (World Reference Base for Soil Resources). It is largely correct to say that latosols are tropical soils, but the reverse is not true because there are many soils in the tropics that are not latosolic. Latosols are red or yellowish-red in colour throughout and they do … Web1) Oil has a density less than water, so it just sits there on the top, not spreading out into the more dense water below. 2) Oil is very nonpolar, meaning that a polar molecule like water doesn't get attracted to it.
