12

Plate Tectonics and the Ring of Fire

Explore the connection between plate tectonic boundaries and global volcanic activity, focusing on the Ring of Fire. Learn why volcanoes frequently form along tectonic plate edges.
Open this exercise →
13

Volcanic Hotspots and Island Chains

Discover how volcanic hotspots form island chains away from tectonic plate boundaries. Learn how moving plates create linear tracks of volcanoes over stationary magma plumes.
