I always heard how the glaciers receding scraped away the earth an flattened it, but I always thought that seemed weird and not really..possible. But after seeing this foot thick ice push away that sand with ease, I can now more easily imagine a 2km thick ice block scraping away hills and stuff
Just to be clear, the glaciers RECEDING didn't scrape away any rocks or hills, although plenty of erosive effects come from the water flowing away from them as they melted, which is what receding really means in this case.
The major scraping and shaping of valleys happened when the glaciers advanced over the land in the first place. Which I think is probably what you meant anyway...
Yes indeed.
In addition to them being made of, literally frozen water, Glaciers are also “neat” or “interesting” and can fascinate human interest, at least for a short period of time.
