Which phenomenon shapes lake basins fed by glacial meltwater in previously glaciated landscapes?

💡 Explanation

When glacial ice melts, isostatic rebound occurs because the land slowly rises as the weight of the ice is removed, creating depressions that become lake basins. Therefore isostatic rebound is the primary driver, rather than freeze-thaw, eutrophication, or underfit streams which are secondary effects or require different geological conditions.
