Re: Dynamic Planet B/C Question Marathon
Ok, I was thinking of a different question with the multiple answers, but on tests I've seen it as 65 m, so 70 isn't far off. Your turn!

Re: Dynamic Planet B/C Question Marathon
Okay!
Describe a roche moutonnee. Be sure to distinguish between the characteristics of the lee and stoss sides of one, and describe what its orientation indicates about the direction of glacier flow
A diagram will help your answer

Re: Dynamic Planet B/C Question Marathon
a roche moutonnee is sometimes referred to as a sheep back mountain. a rock hill is shaped by the passage of a glacier up the smooth gradual side and down the steep, rough, plucked and cliff girt side. the upstream surface is often marked with striations. the abrasion on the stoss side and plucking on the lee side produces an asymmetrical erosional form. the steep side is not facing the approaching glacier, basically the opposite of a drumlin.

Re: Dynamic Planet B/C Question Marathon
What do you guys mean by butterfly? "Aw butterfly"? "He owns everyone's butterfly"?
I'm a SciOly newbie, is that like slang for something? It sounds kinda funny.
Can anyone explain to me this meaning and how it got started?

Um butterfly is just what all the cuss words get filtered to. Anything with a cuss word in it automatically gets filtered to "butterfly"ceg7654 wrote:What do you guys mean by butterfly? "Aw butterfly"? "He owns everyone's butterfly"?

So if I drop the f-bomb right now pigeon it appears as "butterfly"
I just cuss a lot

A tarn is a type of lake formed when in a cirque basin carved out by a glacier.
What is the minimum thickness for ice to flow?

Re: Dynamic Planet B/C Question Marathon
I think the answer to this question at Palatine was 30 m, yes? That one was weird - you got 2 pts if you chose 30 m, 1 pt if you chose 50. The more common answer I've seen is 40 or 50 mnomynameisnotkevin wrote:A tarn is a type of lake formed when in a cirque basin carved out by a glacier.

Re: Dynamic Planet B/C Question Marathon
In the few textbook chapters on glaciers I've read, I've consistently seen 50m.
I also have a question if anybody can help me out; I'm looking for practice problems on glacial mass balance and chart interpretation-- never figured out how to do that last year but now I need to learn, it's killing my scores. For example, if given a table of data titled simply "Glacial Mass Balance, years, glaciers, no units, and a list of positive and negative numbers.... Blah. Are the numbers +/- from each previous year?? As in, if 1995 is -0.07 and 1996 is -0.01, is the total cummulative loss in mass balance -0.08, or -0.01 from the total throughout that year? (if that makes sense...)I'm assuming here that (-) refers to a loss in glacial mass balance (so ablation>accumulation) but I also want to be sure about that.
If anybody could help me out in this department, I'd appreciate it, thanks.

Re: Dynamic Planet B/C Question Marathon
I believe what you're talking about is the ablation/accumulation of glaciers. If they have various #'s, and if they give them as positive or negative, then that means that you're either gaining mass or losing it by various means, such as wind scour, etc.4n6-Chick-1995 wrote:In the few textbook chapters on glaciers I've read, I've consistently seen 50m.
