What is A large boulder that is left behind by a glacier and deposited among rocks of a different type is called?

Answer 1

The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.

Answer 2

Erratic

Answer 3

Glacial drift is the loose and unsorted rock debris distributed by glaciers and glacial meltwaters. As glaciers melt, their remaining load of rocks is distributed in several ways. Rocks may be dropped in place by the melting ice; they may be rolled to the ice margins, or they may be deposited by meltwater streams. Collectively, these deposits are called "glacial drift". "Till" refers to the debris deposited directly by the glacier. Rock debris rolls off the glacier edges and builds piles of loose unconsolidated rocks called "glacier moraine". "Lateral moraines" form along the side of a glacier and curl into a "terminal moraine" at the glacier's downvalley end. Drift and moraines are valuable to geologists because they outline the boundaries of past glaciations.

moraine.

Answer 5
