The volcanic aerosol cloud forms in several weeks by the conversion of sulfur dioxide SO to sulfate aerosol and its subsequent microphysical transfor mations The resulting cloud of sulfate aerosol particles with a residence time of a couple of years Chapter 5. Rigid Earth to Plate Tectonics. Learning Objectives. Know the different types of volcanoes and their associated features. Understand the relationship of the volcanoes to plate tectonics. Know what geographic regions are at risk from volcanoes. Volcanic Eruptions. 1. Why Volcanoes Erupt:. The F of expanding gas builds and pushes magma through the vent. 2. Major Factors in Eruptions:. a. The amount of trapped gas. CO. 2. and Sulfur. b. Silica Content. Chapter 9 . Section 1. Volcanic Eruptions. Volcanoes – areas of Earth’s surface through which magma and volcanic gases pass. In seconds a volcanic eruption can turn an entire mountain into a cloud of ash and rock. Earth Science Fall . 2012 . Vocabulary: . aa. – jagged chunks of lava formed by rapid cooling on the surface of the lava flow . Vocabulary:. Caldera- large basin-shaped depression formed when an explosion destroys the upper part of a volcanic cone or when the magma chamber below a volcano is emptied during an eruption. Chapter 9 . Section 1. Volcanic Eruptions. During an eruption . magma. is forced to the Earth’s surface. Magma. – molten rock below the Earth’s surface. Lava – magma that . flows. on the Earth’s surface. Describe how the locations of volcanoes are related to plate tectonics.. Suggest why volcanoes are found at convergent and divergent plate boundaries.. Describe how . intraplate. volcanoes form.. Volcanic activity takes place primarily at . Volcanoes are locations where molten rock reaches Earth’s surface, and volcanoes can affect landforms and societies.. What You Will Learn. Distinguish between nonexplosive and explosive volcanic eruptions. . Symmetry Breaking. Craig Roberts. Physics Division. Q. C. D. ’s Challenges. Dynamical . Chiral. Symmetry Breaking. Very unnatural pattern of bound state masses; . . e.g., . Lagrangian. (. pQCD. What is a volcano?. A volcano is a vent or 'chimney' that connects molten rock (magma) from within the Earth. ’. s crust to the Earth's surface. . The volcano includes the surrounding cone of erupted material. . Learning . Targets. Compare the types of volcanic eruptions. Describe a method for predicting volcanic eruptions. Volcanic Eruption. Magma collects in . magma chamber. Hot magma . expands. .  creates . Volcanoes. Volcano:. mountain that forms in Earth’s crust when molten material (magma) reaches the surface. . Remember, . magma . is molten rock below ground; . lava. is molten rock at the surface. . Section 2: . Eruptions. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. How does magma type influence volcanic activity?. What is the role of pressure and dissolved gases in eruptions?. Maga. chamber pipe vent. Lavaflow. crater extinct. Pyroclastic flow dormant geyser. What is a Volcano?. A volcano is usually a cone shaped mountain or hill that opens downward to a pool of molten rock below the surface of the earth..
