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. 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.. Volcanic. . Eruptions .

Highlight any information in the title that I know. If the title has words you are familiar with highlight those words in the title, and each time they appear in the passage. 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. . More than 2,000 years ago, Pompeii was a busy Roman city near the sleeping volcano Mount Vesuvius. People did not see Vesuvius as much of a threat. Everything changed when Vesuvius suddenly erupted and buried the city in a deadly blanket of ash that was almost 20 ft. thick!. 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. Why is starch agar used?. -To see if saliva was present and broke down the starch.. Positive control . –used to show what the change looks like. Negative control. – used to what no change looks like.

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. Magma is a mixture of molten rock, volatiles and solids that is found beneath the surface of the Earth.. In some instances, it solidifies within the crust to form . plutonic rocks. . In others, it erupts onto the Earth’s surface to form .
