GEOL 1003 : GEOL Test 1
Document Summary
Exploring the earth system: what does earth system mean, interconnected processes, products of the processes, space and time, components of the system, 1. Physiochemical: inorganic physical and chemical processes shaping. Superposition: older rocks at bottom, younger at top: 2. Lateral continuity: continues across canyon: non-sedimentary principles, 1. Intrusive relationships: igneous intrusion is younger than rock through which it intrudes: 2. Principle of components (inclusions): rock type determines older or younger: additional principles, 1. Chapter 2: rock-forming minerals and rocks1/17/2014 3:25:00 pm. Common mineral classes: silicates (sio4)4, most abundant group of minerals, most stable at earth"s surface, common in igneous rocks, carbonate (co3)2, positive ion (ca, mg, fe) bonded to carbonate ion (co32-, common as aqueous precipitated mineral. Matching: hardness bonding type, density atomic weight and packing, cleavage crystal structure; bonding type, covalent bond sharing electron, ionic bond electrons given or taken.
