The rocks score the side rock faces of Alpine glacier valleys , with horizon scrape marks. Hanging valleys release water that cascade down not having yet enough time to create side valleys. The-immense scale of the ice age cover is evidenced here. I stare out at this Deep time history every time I travel by train to ski in the French Alpes. Awesome sight !
Explains so much in little time. Wonderful. Very helpful explains better then my book even. Thanks. I dont usually watch till the end of these kind of videos but this was an exeption!
I had been searching for clear expectations on this topic for hours but those videos weren’t helpful as they were poorly researched and then i saw this video and this is the one i was looking for...thankssss!
studying for TOEFl as glaciers is a topic that often occurs in this test...so difficult to read articles about glaciers - too many words I do not know and the science behind it is also complicated :D
@@theorrfamily9661 at the end, the test was not so diffucult :-) you can prepare well for the reading and listening part...it was more difficult with speaking and writing, however, as it was difficult to practise on you your own. Good luck!
Can anybody explain why some mountains are covered with scree at the top (like icing on a cake) and not so much at the bottom? Seems counter intuitive that the less stable part of a mountain stays at the steepest and highest point; particularly when you add external forces like climbers, weather and what do you call that falling influencing phenomenon... gravity?
