GEO 102 Study Guide - Midterm Guide: Thrust Fault, Water Cycle, Longitudinal Wave
Document Summary
The ways we collect data about the earth"s interior. Throught astronom y, drilling throught the crust, kim berlite pipes, xenoliths, Ophiolites, siesmatic data (vibrational earth waves a nd earth quakes) the parts of the earth"s interior what a kimberlite is. A pipe that can extend into the mantle what earthquakes are the elastic rebound theory. Explains what causes earthqua kes how seismographs work the types of seismic waves, their similarities and differences. Primary waves - result fro m alternating compression and expansion of material. Also k nown as a compressional wave. Also k nown as secondary waves or shear waves - travel though the earth. Greater amplitude (more shaking) than p waves - can only pass through solids, not liquid or gas. Stress the force acting on a surface. Strain deformat ion resulting fro m stress. Unifor m co mpressional, same in a ll directions. Differential co mpressional, applied force is greater in one direction.
