More About this Product
Students travel with a geologist and explore what the earth is made of. The geologist performs simple tests identifying minerals, which make up most rocks, including quartz and crystals. Students are shown how rocks are formed as well as their properties and characteristics. Included are: igneous rock formation, lava, sedimentary rock, fossil in rock and metamorphic rock. The earth's crust and mantle are in a constant cycle of movement and change. These processes can change one sort of rock into another.
