GEOL 1001 Study Guide - Final Guide: Migmatite, Syncline, Stream Gradient
Document Summary
Elements are o, si, al, fe, ca, c, na, k, mg. Oceanic crust is thinner and more dense than continental crust: mantle: consists entirely of an ultramafic (dark and dense) rock called peridotite (solid) mantle is made of peridiotite (very fe and mg rich, little si). Mantle is 99% solid, 1% liquid, so it has partial melt: core: outer core consist of liquid iron alloy. The inner core consists of a solid iron alloy: understand the rock cycle. Chapter 1: an introduction to geology: when did the earth form, 13. 7 billion years ago (big bang, what are sources of heat in earth? (decay of radioactive minerals, when did the earth form, 4. 57 ga. Outer core is made of fe liquid; generates earth"s magnetic field. Inner core is a very dense solid with too high of a pressure to be a liquid is made of pb: igneous rock can change into sedimentary rock or into metamorphic rock.
