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. By Robbie Barker, Maximilian Bryson, and Brendan . P. etrili. What is a volcano. A volcano is an opening in the Earth’s surface through which magma rises.. Formation of volcanoes. 1.Most volcanoes occur at colliding boundaries.. 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. 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.. 9.1 – How & Where do Volcanoes Form?. One of the most dramatic activities associated with plate tectonics is the eruption of a volcano.. Volcano refers to both:.

Describe factors that can affect the formation of magma. Compare and contrast the different types of magma. Volcanic Eruptions. In the last 10,000 years more than 1500 major volcanic eruptions have been recorded…where and why do these eruptions occur?. 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. . As magma cools underground, it will begin to solidify within Earth’s crust.. Once completely crystallized, these masses of igneous intrusive rock are referred to as INTRUSIONS or as PLUTONS. We will talk about several types of igneous .
