Well you see Strath Haven is really good at science olympiad, and I think they "hack" because it is insane at how good they are! (I'm only kidding, I respect Strath Haven for putting so much effort into SO this year) Anyways how much do you think I should know about sewage treatment? I already know the basic knowledge, but I was just wondering if I should learn more about it. :geek:
Oh. xD Well, you should have a diagram of wastewater treatment with you, because there are a lot of questions on it.

Yeah I have a lot of diagrams on my cheat sheet! I think I have 3 or 4 important ones on sewage treatment :D I am a little confused about point and non-point source pollution. I understand what it means, some examples would be greatly appreciated though.

Hi Everyone,

We just had a quick question about this test: http://scioly.org/wiki/images/4/40/WQ_Kearney_Test.pdf. For number 50, we were getting the answer to be E, but it seems like the answer is A? Could we have some help with this?

The question:
50. A forested watershed is currently under development to
support an extensive commercial shopping center. Which
of the following is not a possible effect on the watershed?
(A) Decreased slope stability
(B) Increased runoff
(C) Increased erosion
(D) Increased sediment and debris
(E) All of the above are possible effects.

Thanks!

What is the best way to learn the invertabraetes? I recently joined this event, and that is what my partner told me to study. I have states saturday, so not something that will take too long.

Well there are many great websites here: http://www.soinc.org/water_quality_b

But, I also highly recommend using Quizlet.com. That website helped me alot. The Water Quality ID forum would also be of some help. Lastly, make flash cards!!! :D

Really, if you don't know them and states is that close, but a chart with them on it on your cheat sheet. You should know some, but that will help a lot.

I would recommend putting a chart on your notes, but try to learn the basic ones like water penny by making flash cards.

I feel like the answer is E. Increased runoff could occur because clearing of the forest for the shopping center would remove vegetation. This would decrease the amount of runoff absorbed. It would also allow the runoff to move more quickly, which would allow the water to transport more sediment, causing increased erosion.

I wouldn't know, but for most questions where "all of the above" is an option, I choose it. :lol: No, seriously, the four answers A-D all seem logical. And really, if more than one makes sense, then chances are (even if you don't think so), it's all of the above, because that question doesn't have an answer: D) A) and B) only (FOR ARGUMENT'S SAKE). Just saying. *shrug*

Does a river's velocity generally increase as one travels towards the river's mouth?

My knowledge on the subject:
The gradient near the head of the river could allow the velocity to increase, but there's a lot of friction.
The gradient near the mouth of the river is very small, but there is less friction.
