What are some suggestions or resources to look into for the mathematical portion of this event? I've been having a lot of trouble with identifying the most salient equations and consistently miss the most points in those sections.

What is the subject for Dynamic Planet next year?

Encyclopedia Britannica is kind of Wikipedia, though you cannot edit it. It is meant to be used for students and therefore it usually summarizes the topic for you. .edu sites are from Universities and are generally more reliable. I recommend http://serc.carleton.edu/mathyouneed/hy ... index.html.

I actually don't know any on the top of my head. Try going to Soinc?

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.

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).

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:
