The consensus appears to be that such a resource (compiled, anyway) doesn't exist. My thought was there might be a lab manual used in undergraduate laboratories that contain these sorts of activities all together...appears not. The advice I was given was to look up different quantitative activities separately on the Internet. :|

A fair bit of the math is basic rate algebra. There are probably earthquake equations, I suppose.

I am new to dynamic planet so I am wondering if you know good links and places to start.

Some math topics:
Isostatic Adjustment/equilibrium
Viscosity and velocity calculations
Movement rates of plates
Earthquake magnitudes and other things
Some more things for another day.

I'm in division B, and movement rates of plates has popped up on every single test I've taken at a tournament this year (i think earthquake magnitudes came up once, but i'm not sure).

Hey does anyone know if glaciers remove land or increase land mass? Because I thought they eroded the land but according to the test on the test exchange the leave behind more land.

If you consider the moraine in front, that's a pretty significant amount of land (if you've ever seen one, you'll know what I'm talking about).

Could someone give me an example of a question about glaciers? Because all I have on my notes are land forms made of glaciers

I haven't seen many glaciers questions at all on tests this year. I think tectonics focuses more on plate movement and mechanisms that drive it and stuff. The only thing you might see about glaciers on a test would probably be isostasy related (ex. what is it called when land originally covered by glaciers rises to its original elevation after the glaciers retreat?).

Can you explain more? I don't know what to put on my notes. And what does isostasy have to do with glaciers?

I think the most important thing you need to know is probably glacial isostatic adjustment, which is basically how land responds to the addition or removal of mass by glaciers. For example, during the last Ice Age, when ice covered a large part of North America, the land beneath it flexed downwards to account for the megatons of ice. And now, since the glaciers have retreated, that land is rising to its original elevation (which is called isostatic rebound/uplift).

If you want more information, this is a good place to start: http://oceanservice.noaa.gov/facts/glac ... tment.html

Hope this helps! :geek:
