← GeographyWhich lacustrine outcome is accelerated where tectonic subsidence exceeds sedimentation rates?
A)Formation of deep, steep-sided lakes✓
B)Expansion of freshwater delta systems
C)Development of saline ephemeral lakes
D)Increased fluvial terrace formation
💡 Explanation
Deep, steep-sided lake formation accelerates due to vertical crustal movement; continuous tectonic subsidence lowers the lakebed beyond natural replenishment. Eustatic adjustment enables deepening, because increased accommodation space is generated rather than infilling and landscape stability.
