5. Dropstone - Wikipedia

   en.wikipedia.org/wiki/Dropstone

   Glacial dropstones, involving rocks falling out of icebergs, are one of the most common types of dropstone preserved in the geological record, particularly when deposited in low-energy deep sea or lake environments. Dropstones differ from erratics found in glacial till in that they are deposited in a lake or marine environments. Dropstones may ...

6. Moraine - Wikipedia

   Moraines are landforms composed of glacial till deposited primarily by glacial ice. [2] Glacial till, in turn, is unstratified and unsorted debris ranging in size from silt -sized glacial flour to large boulders. [3] The individual rock fragments are typically sub-angular to rounded in shape. [4]
