← GeographyWhich outcome primarily results when tectonic subsidence forms a deep lake basin in a humid region?
A)Formation of a saline playa
B)Development of extensive wetlands✓
C)Increased coastal erosion rates
D)Glacial scouring of bedrock
💡 Explanation
When tectonic subsidence creates a deep lake basin in a humid area, extensive wetlands develop because high water availability, shallow gradients near shore, and stable conditions promote dense aquatic vegetation and organic matter accumulation. Therefore wetland formation occurs, rather than a saline environments, changes in erosion rates, or glacial features reflecting distinct processes.
