Q1Psamments, Orthents and Fluvents are suborders of which of the following soil types?

A Alfisols

B Entisols

C Inceptisols

D Vertisols

Explanation

Psamments, Orthents and Fluvents are recognised suborders within Entisols, a soil order made up of very young soils with little profile development. Psamments are sandy Entisols, Orthents are weakly developed mineral soils, and Fluvents are commonly associated with recent alluvial deposits. Alfisols have better-developed horizons and relatively high base status. Inceptisols show more development than Entisols. Vertisols are clay-rich shrinking and swelling soils, so they do not fit these suborder names.
