  1. Earth and Space Science Earth as a System Kelvin Kibler

  2. TEKS Covered • §112.36. Earth and Space Science • (F)  use a wide variety of additional course apparatuses, equipment, techniques, and procedures as appropriate such as satellite imagery and other remote sensing data, Geographic Information Systems (GIS), Global Positioning System (GPS), scientific probes, microscopes, telescopes, modern video and image libraries, weather stations, fossil and rock kits, bar magnets, coiled springs, wave simulators, tectonic plate models, and planetary globes; • (G)  organize, analyze, evaluate, make inferences, and predict trends from data; • (H)  use mathematical procedures such as algebra, statistics, scientific notation, and significant figures to analyze data using the International System (SI) units; and • (I)  communicate valid conclusions supported by data using several formats such as technical reports, lab reports, labeled drawings, graphic organizers, journals, presentations, and technical posters.

  3. Modelling Seismic Measurements • Shaker Table Controlled by function generator Accelerometer to record the signal on different floors of structure The goal will be able to determine the amplitude of the waves recorded and calculate the energy Shaker Table Function generator provides input Find Resonant Frequency of the Structure.

  4. Geotechnical EngineeringApplication • Engineering Design and Analysis Project Description, Background, and Rationale

  5. Lithosphere • The lithosphere is the solid earth beneath the atmosphere and ocean. • Three principal divisions • The Core which is most dense. • The Mantle that is less dense than the core. • Finally the Crust the part where life resides is the least dense.

  6. A more sophisticated Look at the Earth.

  7. Seismic Waves • Body Waves • Primary, or P Waves • Compressional waves • Alternately compress and expand particles in a back and forth motion as their energy passes through the Earth’s interior • Can travel through both solids and liquids • Fastest waves • Secondary, or S Waves • Transverse waves • Shake particles at 90 degree angle to the direction of the waves as they pass through the Earth’s interior • Can travel through solids only
