I'm pretty sure undercutting is erosion underneath another layer of rock, like with a waterfall, while downcutting is just the plain downwards erosion you get in rivers.
ornithology, forestry, entomology, triple E, green generation, water quality, dynamic planet (lakes & rivers), awesome aquifers, meteorology, robot arm, write it do it. :)
A cone of depression occurs when you drop your scoop of ice cream on the ground on a hot summer day.

Okay thank you FueL and Skink. I think I'll go with undercutting as in eroding a lower layer like a waterfall and downcutting as regular downwards erosion.

Any tips for Division C test?
We we're 2nd to last last year. It was horrible.
Anyone still have a vocabulary matching page on the test?
Or specific lakes/river?

Mainly the river valley processes and stream drainage systems (I'm doing the 1st 8 on the rules sheet, my partner is doing the other 6).

Practice reading topographic maps.
Know about erosion/deposition that occurs in streams and rivers.
Know about groundwater, wells, and aquifers.

Basically, Dyn Plnt can be broken down into 3 general topics.
Groundwater
Rivers/Streams
Lakes

Since you're doing the first half, study groundwater and mostly rivers and streams.

Can someone explain what calculations of sinuousity means? Is there a formula to learn?

Thanks.

Before I do a poor job of explaining in my own terms, here's a short Wikipedia article on the topic. I'll be doing most of my studying for this event during this week, and Regionals is on Saturday. This is gonna be fun.
http://en.wikipedia.org/wiki/Sinuosity
The formula is the length of the channel divided by the downvalley length. In other words, it's the length of the river in question divided by the distance of the shortest possible path the river might take. With that said, meandering rivers and streams will have a sinousity greater than 1, while a stream that flows perfectly downhill will have a sinousity equal to 1. I hope this helps, someone please tell me if it's right.
Goodbye Science Olympiad, until next year.

For the competition, are we allowed to use our study notes when they give us the topographic maps?
They can take away everything you have, but they can't take your ability to fight.

Yes. You can use your cheat sheet during any time of the test.
