Final answer:
Soils that were covered by continental ice sheets and have not developed since the last glacial advance are classified as Entisols.
The answer is option ⇒B
Step-by-step explanation:
These soils are relatively young and have not had enough time to develop distinct horizons due to the recent presence of ice sheets.
Soils that were covered by continental ice sheets and have not developed since the last glacial advance are classified as Entisols. These soils are relatively young and have not had enough time to develop distinct horizons due to the recent presence of ice sheets. Glaciers deposited a variety of soil materials on which new soils developed, creating a variety of topographies upon which these soils formed.
The answer is option ⇒B
