What term describes a group of soils that share identical parent material, topography, climate, and biological factors but differ in their age?

Explanation

A chronosequence refers to a collection of soils that are formed under the same environmental conditions—including parent material, landscape position, climate, and organisms—but vary in their age. This allows the study of soil development over time. Other terms like toposequence and catena relate to variations in topography rather than age.
