About This Rocks & Minerals Word Search
Dig into geology and Earth science with this Free Printable Rocks & Minerals Word Search Puzzle! Featuring essential vocabulary from the rock cycle—such as Igneous, Sedimentary, Metamorphic, Quartz, and Mohs Scale—this worksheet is an excellent supplementary activity for elementary and middle school science units.
The puzzle challenges students to search forward, backward, vertically, and diagonally across a 14×14 grid. It formats crisply onto 8.5 × 11" paper with student header lines and a complete second-page solution sheet.
15 Vocabulary Words Included
Here are the 15 words hidden inside this puzzle, along with their thematic definitions for classroom discussions:
SEDIMENTARY
Rock formed over millions of years by the accumulation, compaction, and cementation of mineral particles.
METAMORPHIC
Rock transformed from pre-existing rock by intense underground heat and crushing tectonic pressure.
IGNEOUS
Rock formed through the cooling and solidification of molten magma or surface volcanic lava.
MINERAL
A naturally occurring, inorganic solid substance with a definite chemical composition and crystalline structure.
CRYSTAL
A solid material whose atoms are arranged in a highly ordered, repeating microscopic geometric lattice.
OBSIDIAN
A naturally occurring volcanic glass formed when felsic lava cools rapidly with minimal crystal growth.
GRANITE
A coarse-grained intrusive igneous rock composed mainly of quartz, feldspar, and mica.
QUARTZ
A hard, abundant mineral composed of silicon dioxide, commonly found in sand and granite.
DIAMOND
The hardest known natural mineral on Earth, composed of pure crystallized carbon.
EROSION
The geological process where weathered rock and soil are worn away and transported by wind or water.
WEATHERING
The chemical or mechanical breakdown of rocks and minerals at Earth's surface by weather elements.
MOHSSCALE
A 1-to-10 scale characterizing the scratch resistance of minerals from talc to diamond.
VOLCANO
A rupture in the planetary crust that allows hot lava, volcanic ash, and gases to escape from below.
LUSTER
The way light interacts with the surface of a crystal, rock, or mineral (e.g., metallic or glassy).
GEOLOGY
The scientific study of the Earth, its physical structure, rocks, minerals, and natural history.
3 Fun Ways to Use This Printable in the Classroom
Make the most of this worksheet with these creative lesson and activity ideas:
- Rock Cycle Diagram Relay: After finding all words, have students draw the 3 main rock types (Igneous, Sedimentary, Metamorphic) and illustrate the arrows showing how one turns into another.
- Mohs Hardness Scratch Lab: Pair this worksheet with physical mineral specimens (calcite, quartz, gypsum) and scratch tools (penny, steel nail) to test hardness rankings.
- Geology Flashcard Quiz: Have students write the definition of their favorite found mineral on an index card and test their lab partner.
