About This Product
Rocks record how the Earth formed and how its continents took shape, and handling real specimens is a direct way for students to learn this. With equal numbers of igneous, sedimentary and metamorphic samples, the collection gives a school or college class enough material to compare the three groups side by side, and it can also be the starting point of a rock collection of the school's own. The Expanded Rock Collection can be packed for export to Montenegro, Qatar, Afghanistan, Guyana, the Comoros and Paraguay.
