Correct Answer:
Option D —
Cryogenic processes
The term Cryogenic comes from the Greek words kryos (meaning "ice" or "cold") and genes (meaning "born" or "produced"). In geomorphology and geology, these processes refer to the physical and chemical actions associated with frozen ground and ice.
Permafrost: Ground that remains completely frozen (at or below 0° Celsius) for at least two consecutive years.
Glaciations: The process or state of being covered by glaciers or ice sheets.
Defrosting and De-glaciations: These represent the melting phase of the cycle, where ice retreats and frozen ground thaws, significantly altering the landscape through erosion and sediment deposition.
