Answer 1

A) Alluvium( alluvaial soil) often contains valuable ores such as gold and platinum and a wide variety of gemstones. Such concentrations of valuable ores is termed a placer deposit.

B) Black Earth (Black soil )is a black-coloured soil containing a very high percentage of humus — 3% to 15%, and high percentages of phosphoric acids, phosphorus and ammonia.

C) The red color in soil usually indicates a high amount of iron, in the form of iron oxide, that coats the particles of the soil. The iron oxide can be inherited from the parent material or can form as a result of intense weathering over a long period of time

D) Laterites consist mainly of the minerals kaolinite, goethite, hematite and gibbsite which form in the course of weathering. Moreover, many laterites contain quartz as relatively stable relic mineral from the parent rock. The iron oxides goethite and hematite cause the red-brown color of laterites.
