Document Summary
1) know terms associated with earthquakes: epicenter, hypocenter, seismograph, etc. Epicenter - on the surface above the hypocenter. Seismograph- allows us to locate earthquakes, determine the time, and inform people of any dangers. 3) understand different fault types and the stresses that cause them. Strike-slip fault - stress is both vertical and horizontal. 5) folding in rocks and where it occurs within the earth. 9) stratigraphic principles: lateral continuity, superposition, original horizontality, etc. Lateral continuity - layers can be matched up on opposing sides when there"s a portion missing in the layers. Cross-cutting relationship - having a dike in the layers. Index fossils - fossils of widely distributed organisms that lived during only one short time period. Uses - to define and identify geologic periods. 12) beach drift, longshore currents, emergent coastlines, etc. know effects of these activities and terminology.
