Oldenborgh. 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!. Chapter 9 . Section 1. Volcanic Eruptions.

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. 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. . Volcanoes are locations where molten rock reaches Earth’s surface, and volcanoes can affect landforms and societies.. What You Will Learn. Distinguish between nonexplosive and explosive volcanic eruptions. . Section 18-1. Magma. Objectives:. 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?. Learning . Targets. Compare the types of volcanic eruptions. Describe a method for predicting volcanic eruptions. Volcanic Eruption. Magma collects in . magma chamber.
