Question
The collective name for glacially derived debris is ‘glacial drift’ and it is subdivided into ‘glacial till’, which is an unsorted collection of boulders, gravels, sands, and clays that has been deposited primarily by ice; and if the debris has been deposited by the joint actions of ice and water from melt-water streams, it is referred to as fluvioglacial material. Whenever deposits are influenced by the actions of running water, they become more sorted in profile with smaller and medium sized debris, such as clays and sands, deposited over larger-sized pebbles and boulders.
True or False
Explanation / Answer
True
Whenever deposits are influenced by the actions of running water,they become stratified with heavier materials at the bottom and lighter materials at the top.(smaller and medium sized debris, such as clays and sands, deposited over larger-sized pebbles and boulders.)
