Here are links to two interactive web features. You can build your own volcano and watch it erupt! You can also build a geyser (which is much like a volcano) and alter its characteristics.
1) Virtual Volcano
- As you adjust the gas content and viscosity of the magma, try to predict which type of eruption will occur.
2) Geyser Surpriser
- As you work through this interactive, think about how volcanoes and geysers are similar.
