GEOL 1001 Chapter : Geology 1001
Document Summary
Chapter 1: formation of the universe: plays a role in everyday life, basic understanding, think through scientific problems. Stellar nucleosynthesis: 92 naturally occurring elements, stars fuse nuclei very hot, fusion continues until iron forms, supernova death of a star, violent explosion, fusion of nuclei for heavier elements: cobalt and heavier. Small relative to other planets: outer planets. Gas and ice giants: asteroids: chunks or rock and or metal, comets: ice with a long tail, 4. 57 ga solar system forms, earth forms: planetismal homogenous heat during collision. Chapter 3: minerals i. e. granite is made up of many minerals. A rock is made up of two or more minerals. How they can be destroyed: melting: heat breaks the bond, dissolving: solvents (mostly water) break atomic bonds, chemical reaction: reactive materials break bonds. Metallic and non-metallic: hardness: scratching resistance of a mineral. Where the rock splits easily along flat surfaces. Crystal faces only occur on external surfaces.
