GEOL 1001 Study Guide - Plate Tectonics, Partial Melting, Isostasy
Document Summary
9: crags, cracks, and crumples: crustal deformation and mountain building: mountains, attractive landscape features for humans. Inspire poetry and art: mountains provide vivid evidence of tectonic activity, they embody. Uplift: process that raises surface of the crust. Deformation: process by which rocks bend or break in response to compression, tension, or shearing. Sedimentation: constructive processes build mountains up , destructive processes tear them back down again, orogenic belts, mountains are born and have a finite lifespan. Young mountains are high, steep and growing upward. Old- age mountains are deeply eroded and often buried: deformation, orogenesis causes deformation, consisting of . Shearing: deformation is a force applied to the rocks, change in shape via formation is called strain, structural geology is the study of rock deformation, deformation strain creates geologic structures. Fold- layers that are bent by slow plastic flow. Folds- layers that are bent by slow plastic flow. Foliation- planar metamorphic fabric: deformation, deformed terrain passes into non- deformed terrain.
