How does a glacial fjord form? What does it tell us about climate change after glaciation?

What will be an ideal response?


Answer: Erosion from valley glaciers transforms stream valleys into glacial troughs. In the case of fjords, the mountain valleys are near the coast. Glaciers erode their beds below sea level, and when the glaciers retreat, seawater flows in to submerge the valley. After the glaciation and subsequent sea level rise, the trough is further submerged.
