Students investigate the influence of magma viscosity on the shape of a volcanic cone. Then, they explore nature and motions of lava flows and learn about the importance of lava flows as the building blocks of Mount Rainier. Students will: How do lava flows influence volcano structure and type, specifically at Mount Rainier, Mount St. Helens, and Kilauea?
Recommended level: Middle School: Sixth Grade through Eighth Grade
1. Magma Viscosity and Volcano Shape
2. Lava Flows: Nature, Motion, and Building Blocks
