SCI 285 Study Guide - Midterm Guide: Continental Crust, Oceanic Crust, Plate Tectonics
Document Summary
Correctly label the internal parts (four layers ) of earth in order and composition. Crust is composed of brittle rocks; thinnest part of the earth. Mantle of plastic" solid, denser rocks; biggest part of the earth. Outer core is liquid iron, inner core is solid iron. Explain role of convection in moving tectonic plates. Recognize 2 types of crust: dense oceanic or less dense continental types. Explain what happens during continent-ocean collisions is result of density differences in 2 crust types. Explain how melting of subducted crust leads to emplacement of plutons and chains of volcanoes. Correctly demonstrate the three types of plate motion. 3. 1: differentiate/demonstrate convergent, divergent and transform plate motion. Explain how igneous, metamorphic and sedimentary rocks form in the rock cycle; Correctly identify igneous rocks as crystallizing from magma or lava; Correctly identify sedimentary rocks as being formed from other rocks except for limestone; Correctly identify limestone as forming from skeletal material (shells, corals) in marine settings;
