Which mechanism creates steep-sided fjords after glacial retreat?

💡 Explanation

When glacial ice erodes a U-shaped valley, differential erosion occurs because ice preferentially scours weaker rock formations and carves deeply on a massive scale. Therefore fjords develop, rather than uplift involving rebound or tectonics, or caldera collapses which initiate with different geological processes.
