I have a question about the types of coal. On a test I have taken recently it says that bituminous and lignite are sedimentary rocks, where as anthracite is metamorphic. On the list it states that all are sedimentary. Which one is right, and which one should I answer with(during other tests)? Anthr...

I remember seeing a test where they had a picture of the volcano itself and you needed to identify it. But this was in a 2010 Earthquakes and volcanoes test. What kind of math of anomalies was it? Oh gosh, I'm not sure I remember entirely. There were some Bouguer anomaly calculations, and a couple ...

I'm not from Ohio, but I definitely want to talk about it :) So how was it? (in comparison to, say, the Westlake test, since that's the hardest one I've taken so far) Oh my gosh I thought it was insane. I don't think I've ever known so little on a dynamic test before. It was in stations, first of a...

Does anyone from Ohio want to talk about that dynamic test? Holyyy crap

Can you explain how you know what to draw for the reversals? If the question doesn't specify what it wants, draw it like this: the two strips closest to either side of the mid-ocean ridge would be of normal polarity because that's what's being formed now, so it's our "normal". And then yo...

What do you recommend for the holes that Tulane leaves out? Such as Aulacogens and hazard mitigation? Wikipedia's always a good place to start. This is a good starting place for earthquakes and volcanoes (I think it has some hazard mitigation stuff?). USGS also has a lot of good information about e...

Should the Uniformitarianism be attributed to James Hutton or Charles Lyell? On previous tests dynamic tests I had taken, and on several online resources attribute it to James Hutton as his main achievement. However, we are just starting our evolution unit for AP Bio, and my textbook mentions both ...

Any recommendations on notable orogenies to research? I have the four Appalachian ones, plus seven or eight from the Western US, and I don't really have the time to cover every orogeny in existence (state is in two weeks and I have four other events). Seems like you already have a pretty comprehens...

Yup you're right!
