← GeographyWhich consequence results when isostatic rebound lags erosion in island archipelagos?
A)Increased offshore sediment oxygen depletion
B)Extensive glacial erratic deposition remains
C)Progressive island submergence occurs✓
D)Accelerated formation of volcanic atolls
💡 Explanation
Progressive island submergence will occur because isostatic rebound counteracts the effects of erosion. The mechanism is a rate-limiting process of adjustment; therefore, the islands will continue to sink rather than rise with erosion, potentially leading eventually to full submergence.
