<p>In light of this and threads that have already been created for at least one other AP course, it is best to begin an open question-and-answer dialogue to reaffirm the concepts that we have learned up to this instant. </p>
<p>I should state that it is best to focus your questions on a specific concept as to not overburden the individual responding and to promote relatively frequent replies.</p>
<p>Also, do not feel absolutely obligated to answer a question; commentary is perfectly fine. Please feel free to reflect on your personal experiences in the course or any outlooks, insights, or additional comments that you may have.</p>
<p>what review book are you all using? i’m self studying with PR, will it be enough for a 5? some of the practice exam questions seem a bit too obvious…</p>
<p>and you can use scrubbers and electrostatic precipitators.</p>
<p>^We need to be reviewing on this post, not discussing the score ranges. For a 5, just try to get around 95 points. Don’t worry too much. If you study, it will happen.</p>
<p>OK, new question.
What is the difference between primary and secondary ecological succession?</p>
<p>^ primary succession - The building of an ecosystem in a lifeless are where there is no soil secondary succession - Rebuilding of an ecosystem after a disturbance such as a large fire; However, the disturbance leaves the soil is intact
…this is a basic description, feel free to add any more information.</p>
<p>Eutrophication- Too many nutrients in the body of water for whatever reason (mostly caused by agricultural runoff). Causes algae and plants to grow, but they take up the dissolved Oxygen in the body of water. Eventually, fish and other aquatic species die as they become suffocated from lack of Oxygen.</p>
<p>Explain the Coriolis Effect in the atmosphere.</p>
<p>i tired looking it up once but i never figured out how it pertains to the atmosphere… i know its something like, if you are rotating, then things that go straight look like they’re rotating? idk</p>
<p>the coriolis effect is caused by the rotation of the earth, it shears the normally north-south hadley cells so that wind now blows from the west or east</p>
<p>does anyone know if laws and acts are going to be a big part of the test? PR has so many of them…</p>
<p>I think the laws aren’t necessarily obligatory so much as helpful on the FRQs… maybe there are a couple of questions about laws (at least in Barron’s there are a few) but not as many as the purely science concepts.</p>
<p>Edit: And I’ll add a question… The United States has ___ percent of the world’s population but uses ___ percent of the world’s commercial energy.</p>
<p>ANSWER: The United States has <em>5%</em> percent of the world’s population but uses <em>25%</em> percent of the world’s commercial energy.</p>
<p>QUESTION: Ammonium ions are converted to nitrite ions and nitrate ions through the process of:
A) nitrification
B) nitrogen fixation
C) denitrification
D) assimilation</p>
<p>Has anyone been using the 5 Steps to a 5 book for APES review? I’ve been looking at it the past few days at Borders, and it seems to me that at least in the first chapter (about earth science concepts) it goes into much more detail than I ever learned. For example, it takes about P- vs. S- waves and I don’t remember that being a subject on any of the practice tests I’ve taken?</p>
<p>Is 5 to a 5 just more detailed than we need or am I missing a lot of info in my studying?</p>
<p>Barron’s is best for actually learning the material, but I’m assuming that since it is like two weeks before the exam, you guys want to cram, and for that, PR is probably best. I used PR last year and got a 5.</p>
<p>I have 5 steps to a 5. Not recommended. I’m pretty sure the author wrote it with no reference to the actual exam. The multiple choice questions are very easy, none of the frq’s have any math in them like on the real exam, and some chapters are not very comprehensive, especially the pollution one.</p>
Can someone post the grading system of some other review book?</p>
