What is Volcanism & Volcanic Activity?

The Hawaiian Islands from Space

 As part of our study of Plate Boundaries, we discussed the process of mountain building - folding and faulting, and now we want to explore the processes of volcanism. 

It's important to remember that volcanism isn't just volcanoes, its also geysers, hot springs, travertine terraces and the beautiful features that are created that show our planet is active and alive

Volcanism takes place at subduction zones, diverging plate boundaries and hot spots. They are beautiful features, powerful forces, and tourist attractions!  We want to understand some of the key types of landforms created by volcanism, and also want to understand the benefit and hazards of volcanic activity. 

In addition, we did a deep dive into the nature of shield and composite (strata) volcanoes, and explored their features, and their key characteristics.  We looked at shape, lava type and viscosity (runniness), and the type of explosions. 

We also discussed the idea of Hot Spots.  In particular, we briefly looked at Hawaii, and Yellowstone National Park. 

You should also be able to identify and briefly describe Geysers: Geysir, Iceland


Hot Springs: Blue Lagoon, Iceland
Travertine Terraces: Pamukkale, Turkey
