Solar System Planets Comparison to Earth 5. Layers of the Earth Crust Mantle Core 6. Geologic History of the Earth Precambrian Paleozoic Mesozoic Cenozoic 7. Spheres of the Earth Lithosphere Hydrosphere Atmosphere Biosphere 8. Continental Drift Alfred Wegener 4 items of proof Not accepted at time of development 9. Plate Tectonics J. Tuzo Wilson Plates move about by convection currents in the mantle of the earth 10. Earthquakes Occur due to plate tectonics The most costly natural disaster Measurement of earthquakes o Seismograph and the Richter Scale 11. Landform Types Six types brought about by plate tectonics Vary according to elevation and relief 12. Isostatic Movement Rebounding of the earth’s crust after a weight has been removed 13. Folding Earth’s crust is pushed up 14. Faulting Rock either fractures or pulls apart o Subduction o Extension o Collision o Strike Slip 15. Volcanoes Three Main areas Types of Volcanoes Vesuvian Hawaiian Benefits/Negatives 16. Rocks Igneous o Fire formed rock Sedimentary o Deposits of broken materials that accumulates Metamorphic o Rock’s structure is changed by pressure, heat and moisture 17. Rock Cycle Fig. 6.8 (p. 89) 18. Mining Must determine if a mineral is worth mining Extraction of Minerals o Strip Mining o Open Pit Mining o Underground Mining Oil and Gas Athabasca Oil Sands 19. Gradation Three processes: o Weathering Mechanical Chemical o Transport o Deposition 20. Mass Wasting The energy that is exerted by gravity on a load 21. River Landscapes Three ways that rivers transport materials: o Solution o Suspension o Saltation 22. Wind Landscapes Most often found in desert and steppe regions Various types of Sand Dunes (Fig. 8.7) 23. Coastal Landscapes Wind and water come together 24. Glaciers Formation Types o Continental o Alpine Erosional Features Depositional Features 25. The Hydrologic Cycle Precipitation Surface Runoff Groundwater Evaporation Transpiration Condensation 26. Types of Clouds Cumulus Stratus Cirrus 27. Oceans Cover 2/3 of the planet Many different layers within the ocean with different characteristics 28. Waves Caused by the movement of energy through water 29. Tsunamis Giant waves Caused by major tectonic forces on the sea floor Tsunami development 30. Ocean Currents Creation of ocean currents is dependent upon numerous factors 31. El Nino Occurs every 3 -7 years Change in global climatic patterns 32. La Nina 33. Tides Spring Tide Neap Tide 34. River Patterns Types of Drainage Patterns o Dendritic o Trellis o Parallel o Radial o Deranged 35. Stages in River Development Youth Maturity Old Age 36. Lakes NAFTA 37. Wetlands Bogs Marshes Swamps Fens 38. Water Pollution Physical Biological Chemical 39.
