glacial till deposit |
The real answer's pretty simple: glacial till is the unsorted, unstratified mass of sediment, ranging in size from clay to boulders, transported and deposited by glaciers. Beck sort of got to that, although to avoid the stink of plagiarism he rearranged the answer and employed his thesaurus to define till as,
"...a catch-all term of sorts, referring to material that is not found in layers and that consists of various materials of various sizes."
Yeah, that's what we said: "unstratified [and] unsorted," although "catch-all" is a bit of a misnomer. Forced, however, to fit his answer into the old DMS framework – at least three sections plus an introduction, length of 300-500 words – Kevin had to go a little further afield. In doing so, the onetime physics student proved he had no idea what he was talking about; starting with his very first sentence:"Most children and adults know the essence of what a glacier is: a very large, often beautiful, and – especially in the case of the Titanic, famously sunk by colliding with a glacier in 1912 – potentially hazardous chunk of ice." |
- "Glaciers are... are moving masses of ice... like frozen rivers, albeit very slowly flowing ones."
- "...the effect of the Earth on glaciers is limited in time and impact..." – Say what?!
- "Outwash is water-transported material found in layers, mostly sand and stones"
- "Till is ultimately re-arranged [sic] by rivers, leaving no organized patterns of stratification." – Uh, no, fluvial "re-arranging" stratifies and sorts the sediment, you idiot.
- "Till runs seamlessly into moraines, and in fact sometimes forms entire moraines." – We can't even figure out what that is supposed to mean!
