← GeographyWhich process explains a coastal periglacial lake transformation into a lagoon following rising sea levels?
A)Isostatic rebound overcomes marine transgression
B)Barrier island migration reverses drainage patterns
C)Marine inundation breaches thermokarst features✓
D)Glacial till deposition raises regional elevation
💡 Explanation
When sea levels rise in periglacial regions, marine inundation can breach existing thermokarst features because melting ice creates depressions, which are then filled with saltwater. Therefore, marine inundation is the process that transforms a coastal periglacial lake into a lagoon rather than tectonic uplift or other geomorphic processes causing different landscape changes.
