Why are waterfalls likely to occur in hanging valleys?
Answer and explanation
Correct answer: The main glacial valley is cut deeper than the tributary valley
A hanging valley is a tributary glacial valley left at a higher elevation than the main valley. The main glacier is larger and more erosive, so it cuts its trough much deeper than the smaller tributary glacier cuts its valley. When the tributary stream reaches the edge of this elevated valley, it drops abruptly into the main trough, producing a waterfall. Therefore option A is correct.
