A …Differentiate between the terms: rock and mineral. Provide the names of six (6) minerals (3 silicates and 3 non-silicates) plus, NINE (9) rocks (3 sedimentary, 3 igneous, 3 metamorphic). Provide an example geographic locality where each mineral species is native and known
B… Physical properties of minerals provide a means to identify common minerals, especially with hand samples. Certain properties can exhibit a range of characteristics making them less useful for identification purposes. List three (3) physical properties that might vary between samples of the same mineral. Explain why such variability may exist.
C…Rather than physical properties<as for minerals>, what are the two (2) general parameters used to assist in
identification of hand-size rock samples?
(Hint: Imagine that we were identifying the rocks in a LAB using a chart– such charts are available in texts, lab manuals, and on web in such sites as geology.com)
2.
A… Describe (list) three lines of evidence for plate tectonics theory. Include the main types of plate boundaries.
B… Divergent boundaries as the Mid-Atlantic ridge are characterized by outflows of basaltic lava. What is the source of these lavas? What are causes the source rock to melt? Transform faults are associated with the Mid Atlantic Ridge. What are these and how do they relate to Plate Tectonics?
C…The west coast of North America (USA) is situated at top of what type of plate boundary? What are the main plates involved?
D…How do plate boundaries relate to earthquakes, volcanoes, and to tsunamis?
