Unformatted text preview: Review Questions 11/12/2007 17:03:00 ← You examine two mineral specimens and find mineral A dissolves readily in water and mineral B apparently does not. What can you predict from this observation? • Mineral A has a large degree of ionic bonding in it’s structure ← Which kind of minerals makes up the greatest volume of rocks (the so-called rock-forming minerals)? • Silicate Minerals ← If Silicate minerals form the major part of the most rocks, what elements would you predict are the most abundant elements in Earth’s crust and mantle? • Silicon and Oxygen ← True or False: If tow different minerals have the same chemical composition, one can correctly predict that they will have the same physical properties. • False, if they have the same composition but different physical properties it is called a polymorph ← Graphite and Diamond have very different value and uses in our society. What gives these minerals such different physical properties? • Differences in bonding and internal structure ← What kind of boundary is the lithosphere-asthenosphere boundary? • A temperature/pressure boundary ← If a continental plate collides with another continental plate, what would you expect to see? • Slow rising and deforming mountains ← Which of the following can be used to identify convergent boundaries involving at least on oceanic plate? • Deep trenches ← New Oceanic Crust is crated at ______________? • Divergent boundaries by upwelling magma ← The atomic number of an element indicates the number of __________? • Protons ← An element of the left side of the periodic table will tend to form a(n)? • Caption ← Which kind of atomic bonding in minerals is characterized by the sharing of electrons? • Covalent bonding ← Quartz has a harness of 7, while halite has a harness of 4. Which would you predict to have the greatest proportion of covalent bonding in it’s internal structure? • Quartz has more covalent bonding ← Geological Time Scale (7.9) • Archean Era o Contain primitive micro life o Proterozoic Era o Phanerozoic Era Youngest about 542 million Periods of the Phanerozoic Subdivided into Epochs (Cenozoic) or stages (Paleozoic and Mesozoic) Paleozoic • Early land plants • Marine Life • Reptiles • Amphibians Mesozoic • Dinos • Mammals • Flowers Cenozoic • Grasses • Grazing mammals Paleogene and Neogene divided into 7 epochs Paleistocene (last 1.8 million years) Holocene (most recent – Last 10,000 years) ← Where would one expect to find the oldest oceanic lithosphere on any given lithospheric plate?...
