According to the Food and Agriculture Organization of the UN:
The soils of the Maldives are geologically young and consist of substantial quantities of the unweathered coral parent material, coral rock and sand. In most of the places, soils are coarse in texture and shallow in depth with a top layer of brown soil (0 to 40 cm in depth) followed by a transition zone on top of the underlying parent material of coral reef limestone (MFAMR, 1995). In some low-lying areas and areas subjected to significant mechanical breakdown from human activity, fine deep soils are found with accumulated deposits of clay. In a lagoon environment (locally called kulhi) the depth of the clay may be substantial due to the accumulation of material from marine and biological sources over a long period of time (MEEW, 2006). In many places, top layers of the soils have a weakly developed structure and at times a 30 cm thick hard-pan layer cemented with calcium carbonate is present, preventing penetration of the roots of most plants except large trees. The water-holding capacity of the soil is very poor due high porosity and very high infiltration rates. The soils of the Maldives are generally alkaline with pH values between 8.0 and 8.8. This is mainly due to the presence of excess calcium and, soils containing higher levels of humus, as in depressions and lagoons, are less alkaline. The soils are generally poor and deficient in nitrogenous nutrients, potassium and several micronutrients particularly iron, manganese and zinc. Though the phosphorus content of the soils is high it is present mostly in the form of calcium phosphate and, thus, remains unavailable to plants.
The Maldives are an archipelago made up of coral islands. They were formed by the gradual build up of coral.
Residual soil is the soil formed from the weathering of the bedrock.
How were the soil of Ganga plains formed
soil formed from streams or lokers is
Black soil is formed from basaltic rooks
soil is formed by weathering because the bigger rock break the little rock and makes soil.
soil is formed in the earth crust by rock breaking up and composting
Soil is usually formed from the rock as a result of weathering of the rocks.
Weathering is the process in which soil, sand, and sediment are formed.
soil is formed by weathering because the bigger rock break the little rock and makes soil.

The pH value of a soil is influenced by the kinds of parent materials from which the soil was formed. Soils formed from basic rocks have a higher pH than soil formed from acidic rocks. Water passing through soil leach nutrients such as calcium and magnesium. These nutrients are replaced by acidic elements such as aluminum and iron. Therefore soil that is formed under high rainfall are more acidic than soil that is formed under arid conditions.
