What is a Volcano? � Volcano is a vent in Earth’s crust through which melted -or molten- rock flows. Molten rock below Earth’s surface is called magma

Types of Volcanoes Shield volcanoes � Common along divergent plate boundaries and hot spots. Are large with gentle slopes Composite volcanoes � Large, steep-sided volcanoes that result from explosive eruptions Cinder volcanoes � Small, steep-sided volcanoes
Volcanic Eruptions Eruption Style � Magma Chemistry � Dissolved Gases Effects of Volcanic Eruptions � Lava Flows � Ash Fall � Mudflows � Pyroclastic Volcanic Eryptions Predicting Volcanic Eruptions
