The Oldest Volcanic Meteorite A SilicaRich Lava on a Geologically Complex Planetesimal Top Left Falsecolor Xray map of a piece of NWA 11119 as seen in a polished thin section Minerals are labeled. 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. Where do volcanoes occur—and why?. Divergent [MOR] boundaries . About 75% of erupted lava is found here. Basaltic magma; low viscosity, therefore it flows easily!. Oceanic crust ranges from about 2 km to 10 km thick. Science ~ chapter 6. volcanoes. Volcanic . Landforms. Section . 3. When you picture a volcano, what shape is it?. Are all volcanoes shaped this way?. Anticipatory set. S . 6.1. .f –. Students know how to explain major features of California geology in terms of plate tectonics. 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. 1/16/13 Volcanic Landforms Notes. Formed from . l. ayers of Lava and ash. shield volcanoes. cinder cone volcanoes. composite volcanoes. lava plateaus . Formed from magma . Volcanic necks. Dikes. Sills, batholiths. 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. . Directions : Define the following terms.. 1. Magma chamber. 1. Magma collects in a pocket beneath a volcano. 2. pipe. 2. A long tube through which. magma moves from the chamber to the surface.. 3. vent. Warning . Know when event is happening. Education . Know what to do when an event happens. Research . Know what will happen in an event. ‘Water’ Volcanoes. . Water that can be hazardous that are due to magma or Lava. 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?. to September 22. 1. Wk. 2 Day 1. Before: Question of the Day. What 3 factors control the style of a volcanic . eruptions?. During: Notes. After: Exit Slip. 2. Three Types of Volcanoes. Shield. Cone. Composite.
