About Rocks and Minerals

Rocks fall into three families: igneous rock cooled from magma, sedimentary rock built from packed grains and shells, and metamorphic rock reshaped by heat and pressure. This crossword moves among all three. Obsidian is volcanic glass that cools too fast to form crystals, while pumice traps so much gas it can float on water. Limestone often holds fossils; under pressure it becomes marble. Quartz, feldspar and mica are the three minerals you see speckling a slab of granite.

Reach for this during an earth science unit on the rock cycle, or after a trip to a quarry, cave or museum mineral hall.
