Answer:
Soil comprises five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three sizes: clay, silt, and sand. The percentages of particles in these size classes are called soil texture.
Some examples are:
Plinthite — which hardens irreversibly upon repeated wetting and drying.
Sulfidic — a horizon containing pyrite which, upon exposure to oxygen, can produce so much sulfuric acid that it kills plants and can cause fish kills.
Petrocalcic — in which so much calcium carbonate is accumulated that it forms a rock-like layer in the middle of a soil
