i. Entices are recent soils, too young to show the modifying effects of their surroundings; therefore, they have no diagnostic layers that would qualify them for membership in any other soil order.
ii. The extreme entisol is a pile of material dumped on a construction site by a bulldozer.
iii. Shifting sand, recent volcanoes, river floodplains, landslides, very cold places, and windy deserts are other likely sites for entisols.
iv. Recent soils are scattered throughout the country because they are not unique products of a particular climate.
v. The productivity of entisols varies from very low, in the case of some arid sands, to very high, as on some floodplains.
