Slide1: Mountains and Volcanoes CHAPTER Mountains and volcanoes form as tectonic plates move. Movement of rock builds mountains. Volcanoes form as molten rock erupts. Volcanoes affect Earth’s land, air, and water. NEW CHAPTER 3.1 3.2 3.3


Slide2: SECTION OUTLINE fault-block mountain folded mountain Movement of rock builds mountains. Folded mountains form as plates push together. 3.1 CHAPTER RESOURCES


Slide3: Fault-block mountains form as the lithosphere is stretched. SECTION OUTLINE fault-block mountain folded mountain Movement of rock builds mountains. Folded mountains form as plates push together. 3.1 CHAPTER RESOURCES


folded mountain: A mountain that forms as continental crust is compressed and rocks bend into large folds. folded mountain KEY CONCEPT SUMMARY Movement of rock builds mountains. fault-block mountain folded mountain 3.1 CHAPTER RESOURCES


fault-block mountain: A mountain that forms as blocks of rock move up or down along normal faults in areas where the lithosphere is being pulled apart. fault-block mountain KEY CONCEPT SUMMARY Movement of rock builds mountains. fault-block mountain folded mountain 3.1 CHAPTER RESOURCES


Volcanoes form as molten rock erupts.: Volcanoes form as molten rock erupts. SECTION OUTLINE lava pyroclastic flow volcano Volcanoes erupt molten rock, rock fragments, and gases. Different types of erupted materials build up different types of volcanoes. 3.2 CHAPTER RESOURCES


Volcanoes form as molten rock erupts.: Volcanoes form as molten rock erupts. SECTION OUTLINE lava pyroclastic flow volcano Volcanoes erupt molten rock, rock fragments, and gases. Different types of erupted materials build up different types of volcanoes. 3.2 CHAPTER RESOURCES


volcano: An opening in the crust through which molten rock, rock fragments, and hot gases erupt; a mountain built up from erupted materials. volcano KEY CONCEPT SUMMARY Volcanoes form as molten rock erupts. lava pyroclastic flow volcano 3.2 CHAPTER RESOURCES


lava: Molten rock that reaches a planet’s surface through a volcano. lava KEY CONCEPT SUMMARY Volcanoes form as molten rock erupts. lava pyroclastic flow volcano 3.2 CHAPTER RESOURCES


pyroclastic flow: A dense cloud of superheated gases and rock fragments that moves quickly downhill from an erupting volcano. pyroclastic flow KEY CONCEPT SUMMARY Volcanoes form as molten rock erupts. lava pyroclastic flow volcano 3.2 CHAPTER RESOURCES


Volcanoes affect Earth’s land, air, and water.: SECTION OUTLINE Volcanoes affect Earth’s land, air, and water. geyser acid rain Materials erupted from volcanoes, as well as heat from molten rock underground, affect Earth’s surface. 3.3 CHAPTER RESOURCES


acid rain: Rain that has become more acidic than normal due to pollution. acid rain KEY CONCEPT SUMMARY Volcanoes affect Earth’s land, air, and water. geyser acid rain 3.3 CHAPTER RESOURCES


geyser: A type of hot spring that shoots water into the air. geyser KEY CONCEPT SUMMARY Volcanoes affect Earth’s land, air, and water. geyser acid rain 3.3 CHAPTER RESOURCES
