Crust _____ Oxidized; primarily composed of Silicate minerals _____ Metallic; not composed of Silicates b. Mantle c. Outer Core d. Inner Core _____ The upper-portion of the Lithosphere e. the entire Core (including Felsics, Mafics, and/or Ultramafics) (i.e., both (c) and (d)) _____ Its upper-portion contains both the lower-Lithosphere and the entire-Asthenosphere f. both Crust and Mantle (i.e., both (a) and (b)) _____ The least-dense layer C) TRUE/FALSE (write T for TRUE, F for False): +2½ Points _____ The Lithosphere is a “plastic-solid;” it has the ability to flow or deform when forces are applied _____ The Asthenosphere is differentiated from the Lithosphere based on differences in material state, not on differences in material composition _____ The Cuyamaca Mtns have thicker Lithosphere than does the Imperial Valley _____ Isostatic adjustment of the Lithosphere occurs upward upon significant erosion of a mountain range _____ Isostatic adjustment of the Lithosphere occurs upward upon significant accumulation of sediments in a depositional basin 1 + +4 Points D) (1) On the diagram below, label the core. (2) Then, accurately draw the location of the lithosphere and asthenosphere. (Do so in any sensible manner, including most easily as it was done on the video. Attempt to indicate the top and bottom of each as accurately as possible at this scale. Labels can be added to the left of the diagram.) (3) Circle the correct answer: If your additions to the diagram were done correctly, they should extend down only at the most to: A / B / C (4) (a) In the space below, draw an enlargement of the upper-portion of the diagram above; your diagram should extend from the surface down to the ~300 km (~180 mile) depth. (b) Then correctly-show, clearly-delineate, and accurately-label the following: Lithosphere, Asthenosphere, Crust, upper-Mantle, and the “Moho” TIM CLIFFE – Earth Science Dept. E) YOUR NAME ___________________________________________ MATCHING: For each of the following statements on the left, choose the best choice from the right. (Write a letter between a through j; each answer +2 Points used no more than once.) 1. Silicon is a(n) _____ a. Element 2. The smallest piece of silicon still retaining the characteristics of silicon is called a(n) _____ b. Atom c. Compound d. Molecule 3. Silica is a(n) _____ 4. The smallest piece of silica still retaining the characteristics of silica is called a(n) _____ 5. Quartz is a(n) _____ 6. Granite is a(n) _____ e. f. g. h. i. j. Anion Mineral Rock Proton Electron Ion 7. Elements are defined based on the number of _____ 8. In general, an unbalanced atom is called a(n) _____ 9. Specifically, an atom that has gained electrons is called a(n) _____ F) +1 Point FILL-IN: 1. “Father” of Nuclear Physics; discovered the nucleus = ____________________ 2. Most-common rock-forming mineral group = _________________________ 3. Name three minerals that commonly make-up a Granite: a) __________________________________ b) __________________________________ c) __________________________________ 3 + G) +2 Points FILL-IN: 1. Sodium (Na) has 11 protons. Thus, it has how many valence electrons? _______ 2. Chlorine (Cl) has 17 protons. Thus, it has how many valence electrons? _______ + +1¼ Points 3. Thus, Na and Cl bond together ionically (i.e., by electron-transfer): Specifically, Na ________an electron from its __________ shell, meaning that its’ gains/loses first/second/third “outer shell” becomes the already-filled __________ shell… and Cl _________ an first/second/third gains/loses electron in its ________ shell, thus filling its “outer shell,” as per the “_______ Rule.” first/second/third The result is a(n) _________ called “Sodium Chloride,” the basis for the mineral compound/element “Halite” (or what’s sometimes called “_____________________”). Rock Salt / Plagioclase Feldspar TIM CLIFFE – Earth Science Dept. H) YOUR NAME ___________________________________________ +3¾ Points DIAGRAM: In the space below, draw a diagram of the Rock Cycle. Draw 5 separate boxes to show the individual components of the Rock Cycle. Draw arrows to represent the processes linking each component. Correctly label everything. For Igneous Rocks, include the same degree-of-explanation as was made on the videos. Properly include the following rocks into the diagram as examples: BASALT, GRANITE, SLATE, GNEISS, MARBLE, SANDSTONE, LIMESTONE, and SHALE. 5 I) +1¼ Point FILL-IN: 1. Who was the “Father” of Neptunism = _______________________________ 2. Who was the “Father” of Uniformitarianism = _________________________ 3. True or False: Neptunism was developed in Edinburgh, Scotland? _________ 4. True or False: The Rock Cycle was developed around Edinburgh? ________ 5. True or False: Basalt is precipitated from cold sea-water:________________ 6. What mineral is #10 on Moh’s Hardness Scale? ______________________ 7. “Hutton’s Unconformity” is located at what “point?” ____________________ 8. What’s an unconformity? Briefly explain: ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ 9. Going back to YOUR “Grossmont College Stratigraphy” diagram (from unit “I. Underpinnings of the Physical Sciences – Video #3”), draw and describe (e.g., what ages?) the Unconformity below Grossmont College (that is, between the conformably-lain Sedimentary Layers above vs. the Granitic “Basement” below): ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ + …
