Volcanic ash can cause engine failure. 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. 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. Volcanoes. In the last section we learned that the outer layer of the earth is called the Crust.. We also learned that the crust is broken into many different pieces called Plates.. The plates are constantly moving because of Continental Drift.. 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. . Tianfeng.
