Here is an animation for middle and high school students that depicts volcanism at a mid-ocean ridge. An introductory paragraph describes what occurs at a rift zone as two plates diverge and magma repeatedly moves up through the rift. The animation consists of two coordinated movie clips--one that shows a cross section of a rift zone and another that provides a view from above the rift. These clips show the volcanism and seafloor spreading that take place as two oceanic plates move apart. Students are supplied with control buttons to play, pause, and scroll through the animation. Labels indicate the key features in the animation. Copyright 2005 Eisenhower National Clearinghouse

| Description | The Digital Library for Earth System Education (DLESE) mission is to improve the quality, quantity, and efficiency of teaching and learning about the Earth System, by developing, managing, and providing access to high-quality educational resources and supporting services through a community-based, distributed digital library. Intended users include students, educators and citizens of all ages, in both formal and informal learning environments. The collection favors resources that convey linkages and connections; the general with the specific, theory with evidence, global with local, and that demonstrate the application of science to solving real world problems. This includes providing access to Earth data sets and imagery, and the tools and interfaces that enable their effective use. DLESE resources are community-contributed, by individuals, organizations, and formal collection efforts. |

| Description | The Middle School Portal 2: Math and Science Pathways (MSP2) supports middle grades educators with high-quality, standards-based resources and promotes collaboration and knowledge-sharing among its users. Educators use MSP2 to increase content knowledge in science, mathematics, and appropriate pedagogy for youth ages 10 to 15. MSP2 employs social networking and digital tools to foster dynamic experiences that promote creation, modification, and sharing of resources, facilitate professional development, and support the integration of technology into practice. MSP2 is a project of the Ohio State University College of Education and Human Ecology, National Middle School Association, and Education Development Center, Inc., and is funded by the National Science Foundation. The partners integrate resources, tools, and services across projects, and support multiple methods of resource discovery to meet the needs of this audience. |

Visualization ES0903 Observe an animation of volcanism along a rift zone. Rift zones are divergent plate boundaries. Most of them occur along the seafloor as mid-ocean ridges. Where two plates are moving away from each other, molten rock rises to the surface, cools, and solidifies. Generally, each eruption of lava splits the rocks formed in the previous eruption, so the youngest rocks are always at the rift. ! Click the image to see the animation. Jen Loomis, TERC
