Dynamic Planet B/C Question Marathon

Question Marathon for Dynamic Planet B/C.

I guess I'll start off with an easy question. How can you tell the direction of a glacier's movement by looking at a drumlin? A roche moutonnee?

[Crazy Puny Man]

For both, the lee side points in the direction of the ice flow. For a drumlin, that is the less steep, sloping side. For a roche moutonnee, it's the opposite--the jagged, steeper side is the lee side and points in the direction of ice flow

EDIT: dang, I'm starting to like these question marathons already

[mnstrviola]

Correct! I think this means it's your turn to post a question

[Crazy Puny Man]

Aw pigeon. Um...

Name two factors that cause glaciers to flow.

Also, a somewhat related question...

Name and describe the ways a glacier moves.

This question (the latter) has kinda bothered me in the past, since I had a lot of information on glacier movement and I didn't really know what to put for this question (that is, I couldn't articulate my answer), and I have a decent idea of what I would put for this question, and I want to see what other people would put

EDIT: should we [hide] our answers?

[mrburrito]

First year doing this , so I am ignorant , but I'll try without using resources . For part a: A downwards slope, and pressure buildup. For part b: Slowly and unpredictably

When this gets called wrong, explain the answer please.

Um...no...

How about this, try looking up the answer yourself. I'm sure you'll find some good resources in the process from which you can study as well

C'mon, there has to be someone out there who knows this! Fozen? PacificGoldenPlover? (can I please just call you "Plover" from now on for convenience? )

From now on, put Pacific's name first, then after thousands of spaces you can put mine... Pacific is uber good at DP

And if the answer isn't posted by the time I finish my HW I will look into it

[mrburrito]

Ok, pressure and gravity, so I was partially correct.

And umm basal sliding, which is when glaciers slide over the terrain it's on, lubricated by liquid water.

I think that's right.

I think that's right.

Also, some glaciers move because internal ice crystals move past one another based on conditions (temperature, weight, pressure). Usually, the top layers of a glacier move quicker than the bottom layers.
Is this right? Thanks.
