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. 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.. By Karanasiou Katerina B1. 07/02/2017. Volcano…. Volcano is open passageway from the interior of the Earth that allows blast rock and gases from the interior to the cortex surface in the form of lava. This activity creates mountains. 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 . How and why do volcanoes erupt?. Hot, molten rock (magma) is buoyant (has a lower density than the surrounding rocks) and will rise up through the crust to erupt on the surface.. When . magma reaches the surface it depends on how easily it flows (viscosity) and the amount of gas (H. 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. 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. .
