The Constructive Side of Volcanoes Viscosity Viscosity is the property of matter that allows it to hold its shape or the property that allows it to resists flowing Low Viscosity means that it is more runnythin like water. Principal Types of Ocean Principal Types of Ocean Basins Basalt Basins Basalt Table 10 Table 10 Common petrographic differences between tholeiitic and alkaline Common petrographic differences between tholeiitic and alkaline basalts basalts Tholeiiti Hot rocks/Fire Rocks. Igneous Rock . Igneous rocks form . when molten rock cools and solidifies. . Molten rock is called magma when it is below the Earth’s surface and lava when it is above.. when molten rock cools and solidifies. MINERALS DOWN UNDER NATIONAL RESEARCH FLAGSHIP. Steve Barnes, . CSIRO Earth Science and Resource Engineering. GA Mineral Systems June . 2012. Fertility (as applied to magmas). Do particular kinds of magmas have a tendency to give rise to ore deposits?. By: Jackson Smith. Type of Volcano. The Yellowstone caldera is a SUPERVOLCANO!. The Yellowstone Supervolcano is still very active, but is not shooting out lava. . It’s considered a Supervolcano because there is a much larger amount of magma in the magma chamber. . “Liquid Hot Magma!”. Igneous Rocks. Rocks formed from cooling of lava or magma. Lava-Melted rock erupted from volcanoes and deposited on the earth’s surface. Cools quickly.. Magma-Melted rock that sits inside the earth in a magma chamber. Cools slowly.. GO. What do you know already about volcanoes?. Let’s learn more. Click on the links below.. What is a volcano?. What is magma and what is lava?. What types of volcano are there?. What causes a volcano to erupt?. Volcanic. . Eruptions . (pages. . 209–216). Magma. . Reaches. . Earth’s. . Surface. (pages. . 210–211). Students will be able to….. Explain what happens when a volcano erupts.. Describe the two types of volcanic eruptions.. . . Here we will compare extrusive and intrusive volcanic features and action. q distinguish magma from lava. q identify intrusive and extrusive igneous features (e.g., sill, dike, . batholith. Mr.McMahon . Learning Objectives . To understand . WHY. volcanic activity occurs.. To understand . HOW. the distribution of Volcanic activity relates to plate boundaries.. To . EXPLAIN . how Volcanic activity can be predicted.. What You Will Learn. Describe the formation and movement of magma. . Explain the relationship between volcanoes and plate tectonics. . Summarize the methods scientists use to predict volcanic eruptions. . Section 3: . Intrusive Activity. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. How are features formed from magma that solidified under Earth’s surface described?. 1. Temperature. 2. Pressure. 3. Addition of fluids. Lava Flows. Pahoehoe. – hot fluid lava. Least viscous. Aa. – forms sharp rock. Blocky – chunky rock. Most viscous. Types of Volcanoes. Cinder Cone – explosive eruptions. 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?. GLY 4310 - Spring. , 2020. 2. Magma Series Definition. A group of rocks that share some chemical, and sometimes mineralogical, characteristics. They share patterns on chemical variation diagrams which suggests a genetic relationship – beyond the scope of this course.
