REVIEW FOR TEST #2 – GEO 109/SCI 210 Winter 2008 KLOSTERMAN The second test will cover all of the material presented in the second module “Solid Earth Systems”. The format will be a combination of short answers and short essays. Below are review questions - I will ask some of these directly as short essays and some in the form of short answer derived from the essay questions. In other words, if you can answer each of the review questions in a complete, accurate and probably lengthy paragraph, you will probably do very well on the test. A complete answer would include definitions, explanations and examples. An accurate answer presents material that is consistent with the presentations/readings. To do this, at least one or two paragraphs would be needed. I will expect very detailed answers to be prepared. You should prepare independently for the test. Students writing identical essays on the test will not receive full credit. I will provide assistance with clarification of essay questions or give comments with respect to ideas you run by me. I will not “start from scratch” and re-present material. You can email me with questions or to review your prepared essays. Some Tips: Concentrate on these questions, your notes, the posted lecture notes on WebCT (along with links, etc) and in-class exercises. For the text, the WebCT notes direct you to the appropriate pages of material related to the content we covered in class. WRITE OUT YOUR QUESTIONS FOR PRACTICE – I think there is a strong connection between your eye, your hand and your brain! BRING A RULER AND A PENCIL COMPASS IF YOU HAVE ONE (I WILL HAVE EXTRAS) Review Questions: 1. Define a mineral and explain what factors control their individual properties. What classification of minerals dominates the earth’s crust? – describe their basic chemical composition and why they dominate the earth’s crust. Mica and Quartz are two examples of this one classification of minerals but they exhibit completely different properties – explain how the properties differ and why. Quartz and Calcite are in two different classifications of mineral and also differ in terms of their properties – explain how the properties differ and why. Geologists define Minerals in very specific terms. Minerals are solids with a specific chemical composition and solid crystal structure that gives it its physical properties. In addition, geologists do not include any organic or man-made materials in their classification of minerals. 2. You should be familiar with the appearance and characteristics of the following rocks: Basalt, Granite, Rhyolite, Limestone, Sandstone, Shale, including identifying visual images.

Basalt SANDSTONE is made up of fine-grained particles (1/16 –2 mm). The sand grains (often quartz) are commonly cemented by silica, carbonates, clay or iron oxides. Sandstone is identified by its sandy texture – which often translates into a gritty feel. Environments in which sandstones form include beaches, sand bars, deltas and dunes.
