Detailed explanation-1: -The answer to this question is moist soil. It is because under the conditions of high temperature and rainfall moist soils are formed in tropical areas.
Detailed explanation-2: -The laterite soil is formed under conditions of high temperature and heavy rainfall. They are the result of intense leaching due to alternate wet and dry periods.
Detailed explanation-3: -The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium.
Detailed explanation-4: -The laterite soils develop in areas with high-temperature and high rainfall. These are the result of intense leaching due to tropical rains.
Detailed explanation-5: -Laterites are formed by the decomposition of different kind of rocks, under conditions yielding aluminum and iron hydroxides. The different theories of origin are discussed, as well as the chemical process of laterization, and the geographic distribution of this peculiar type of clay.
