Middle School Geology End of Unit Lesson Plan Cascades Volcano Observatory Why Study Cascade Volcanoes? Cascade Range Active volcanoes dominate the skyline of the Pacific Northwest. The familiar snow-clad peaks of the Cascade Range are part of a 1,300 km (800 mi) chain of volcanoes, which extends from northern California to southern British Columbia. The volcanoes are the result of the slow slide of dense oceanic crust as it sinks beneath North America (subduction), which releases water and melts overlying rock. This rich volcanic zone contains the well-known landmark volcanoes and approximately 2,900 other known volcanic features ranging from small cinder cones to substantial shield volcanoes. Cascade volcanoes have erupted in the recent past and will erupt again. The time between eruptions is usually measured in decades or centuries, so eruptions are not a part of our everyday experience. Eruptions in the Cascade Range during the past 4000 years. During the past 4,000 years, periods of eruptive activity at various Cascade volcanoes have lasted for a few to tens of years per century.

An eruption happens when magma, gases, or steam break through vents in the Earth's surface. A mild eruption may simply discharge steam and other gases, or quietly extrude lava. A strong eruption can consist of violent explosions that send great clouds of gas-laden debris into the atmosphere, or may consist of explosions that blast sideways from a collapsed portion of the volcano, as happened in the 1980 eruption of Mount St. Helens. Eruptions can alter the land and water locally through lava flows, lahars, pyroclastic flows, and landslides. A lava flow moves through an intersection. Lava entering the sea poses special risks. A lahar is a mixture of volcanic ash, rock, debris, and water that can travel quickly down the slopes of a volcano. A pyroclastic flow is a rapidly-moving mixture of hot, dry rock fragments, ash, and hot gases which knocks down, buries, or burns everything in its path.
Videos - Geology Geology may be a science that moves very slowly, but a number of videos bring the subject to life for students. Education World compiled some great videos that will get kids excited about the topic. For each one, we include a description and grade level. We also note the video’s capacity for engagement (“cool factor”). The Geology and Formation of the Western Land of U.S. Source: World-earthquakes.com. Grade level: Sixth grade or higher Run time: 44:59 Description: This rather dramatic video shows geology in action—specifically, how the western part of the United States came to look the way it does. Cool factor: Not as cool as some, but dramatizations of geologic activities add interest. National Geographic Colliding Continents Source: National Geographic Grade level: All ages Run time: 50:05 Description: This video is a documentary of the Earth’s violent past and the movement of the tectonic plates.
