Earthquake Lesson
Plate Tectonics. Brief Structure of the Earth Divided into layers: –Core, mantle, crust.
Chapter 11, Section 1 Forces Inside the Earth. Elastic Deformation The ability of an object to bend and stretch without breaking.
Earths Crust Convection currents Continental drift – idea that continents have moved slowly to their current positions due to convection currents in.
Chapter 9 – FOLDS, FAULTS & GEOLOGIC MAPS. Rock Deformation Stress –Force acting on surface, per unit area Pressure –Confining (uniform) Stress is equal.
Intro Objective 10/14/2011 Describe the three major types of folds and faults by modeling them. Does rock bend or break or both?
Intro
Stresses, Faults, Folds, and Earthquakes. Types of Stresses on Layers of Rocks:
