-
B.
glacial lake basin

-
C.
subsidence lake
A subsidence lake is a body of water that forms in a depression created when the ground surface sinks or collapses due to natural processes or human activities such as mining or groundwater extraction.
-
D.
glacier
A glacier is a massive, persistent body of dense ice that forms on land from accumulated snowfall and slowly flows under its own weight, reshaping the landscape over time.
-
E.
