Document Summary
What to know about volcanoes for the quiz: different types of volcanoes and their relationship to plate tectonics, examples of types and where, impacts of volcanoes and their linkages to other hazards, benefits, no questions on yellowstone. Lava is magma on the earths surface: most volcanoes are near plate boundaries. Note: think about relationship between volcanic activity and other hazards we"ve discussed. *important diagram in screenshot on desktop background know how to label it: shield volcanoes hotspots , straddle volcanoes subduction. Types of volcanoes: for two tables: understand relationship between explosivity and the danger/risk factor, and frequency, different shapes and eruptive styles based on chemistry and viscosity of magmas. Composite volcano or stratovolcano think calbuco chile (video in class) Two main types: shield and stratovolcano/composite volcano: composite (strato)volcanoes. Built from a combination of lava flows and pyroclastic deposits. Mount fiji, chile, etc. (case studies in textbook) Magma that cools over a long period of time makes granite.
