Apart from the impact of an asteroid, the explosive eruption of a volcano releases more energy above ground in a small region than any other natural event. This set presents actual samples of the rock and ash types produced in volcanoes around the world.

These 7 samples are colorfully displayed in a 5 inch by 7.5 inch snap-close plastic case, and each set includes a detailed information sheet.

Availability: Usually ships in 2-3 business days.
