Grand River Collegiate Institute: Physical Geography Geosphere Unit Review Format: Matching, Multiple Choice, Short Answers Topics: 1) Rocks and Minerals (page 86-90) Characteristics, types, Rock cycle 2) Plate Tectonics (page 95-104) Plates, Types of plate boundaries, location of “Ring of Fire” 3) Seismic Activity (page 121-131) How earthquakes occur, measuring seismic activity Types of waves, magnitude, faults Vancouver Earthquake Review Crossword 4) Volcanoes (page 107-116) 3 types of magma, silica content, viscosity 3 types of volcanoes and examples of each, hot spots Features (diagram – conduit, chamber, fumarole….) Why Iceland has so much geothermal energy 5) Tsunami (page 132-135) Causes, warning system 6) Weathering and Erosion (page 140-148) Physical vs. Chemical, rates, damage, mass-wasting Caves – process 7) Topographic Maps Contours, features, how to read them Review Questions: 1) You should know the following key terms and what they mean (definition): Weathering (physical vs. Fumaroles, conduit, ash chemical) cloud, magma chamber Rocks and Minerals Topographic map Igneous, Metamorphic, Geographic Information Sedimentary Systems Map (GIS) Mass Wasting Earthquake Contour lines, intervals Seismology Magma Focus, Epicentre Plate Tectonics Faults 2) List four important characteristics of a mineral. P, S, surface waves Erosion Shield, composite, cinder volcanoes Tsunami Richter Scale Stalactites Stalagmites 3) Illustrate the rock cycle. Use terms igneous, metamorphic, sedimentary, weathering & erosion, magma melting, solidification, deposition. Grand River Collegiate Institute: Physical Geography 4) Complete the following: Seismic waves 5) Complete the following diagram. 6) Topographic Maps a. What is the contour interval? _________ b. Shade in the highest peak c. Use a dotted line to show where you think a river is. d. Use an arrow to show which way the river is flowing. e. Add bold index lines every 500m f. Add a depression right here. 7) Why is Vancouver likely to experience a major earthquake (include background information on seismic activity, geology in the area). 8) Describe one major tsunami event (area affected, date, cause, damage) discussed in class.
