← GeographyWhich landform results when isostatic rebound follows deglaciation within a fjord valley containing varying bedrock resistance?
A)Elevated marine terraces at varying heights✓
B)Increased frequency landslides due steep slopes
C)Extensive patterned ground from permafrost
D)Development of kettle lakes in the valley
💡 Explanation
When isostatic rebound occurs after deglaciation of a fjord, differential uplift happens because the earth's crust readjusts, resulting in higher rates of post-glacial uplift on stronger areas. Therefore raised marine terraces form at varying altitudes based on bedrock resistance, rather than landslides, patterned ground or kettle lakes which require different geomorphic conditions and mechanisms.
