| IGNEOUS ROCK | ROCK FORMED BY THE COOLING AND HARDENING OF HOT LIQUID ROCK |
| DIKE | NARROW, FLAT FORMATION OF IGNEOUS ROCK FORMED IN VERTICAL CRACKS IN THE EXISTING ROCKS |
| CEMENTATION | PROCESS BY WHICH SEDIMENTS ARE CEMENTYED TOGETHER BY MINERALS DISSOLVED IN WATER TO FORM SEDIMENTARY ROCK |
| LCCCOLITH | DOMELIKE INTRUSION THAT PUSHES OVERLYING ROCKS INTO AN ARCH AND HAS A FLAT FLOOR |
| CONTACT METAMORPISM | TYPE OF METAMORPHISM THAT OCCURS WHEN ROCKS ARE HEATED BY CONTACT WITH MAGMA OR LAVA |
| IGNEOUS ROCK | ROCK FORMED DEEP WITHIN THE EARTH |
| EXTRUSIVE ROCK | IGNEOUS ROCK FORMED FROM LAVA AT THE EARTH'S SURFACE |
| COMPACTION | PROCESS BY WHICH LAYERS OF SEDIMENTS ARE PRESSED TOGETHER TO FORM SEDIMENTARY ROCKS |
| BATHOLITH | HUGE, IRREGULARLY SHAPED INTRUSION THAT EXTENDS DEEP INTO THE EARTH'S CRUST |
| INTRUSION | IRREGULAR FORMATION OF INTRUSIVE ROCK FORMED BY MAGMA BENEATH THE EARTH'S CRUST |
| EXTRUSION | IGNEOUS ROCK FORMATION THAT FORMS ON THE EARTH'S SURFACE |
| FOLIATED | TEXTURE OF SOME METAMORPHIC ROCKS IN WHICH MINERAL CRYSTALS ARE ARRANGED IN PARALLEL BANDS ALONG WHICH THE ROCKS TEND TO BREAK |
| METAMORPHISM | CHANGING OF ONE TYPE OF ROCK INTO ANOTHER AS A RESULT OF TREMENDOUS HEAT, GREAT PRESSURE, OR CHEMICAL REACTIONS |
| SEDIMENT | SMALL PIECES OF ROCKS, SHELLS, OR THE REMAINS OF PLANTS AND ANIMALS THAT HAVE BEEN CARRIED ALONG AND DEPOSITED BY WIND, WATER OR ICE |
| LAVA PLATEAU | LAYERS OF LAVA THAT BUILD UP ON A FLAT AREA ON THE EARTH'S SURFACE |
| PORPHYRY | IGNEOUS ROCK WHOSE COOLING RATE HAS CHANGED AND THUS HAS TWO OR MORE DIFFERENT-SIZED CRYSTALS |
| REGIONAL METAMORPHISM | TYPE OF METAMORPHISM THAT OCCURS OVER LARGE AREAS WHEN ROCKS BURIED DEEP WITHIN THE EARTH ARE CHANGED BY INCREASES IN TEMPERATURE AND PRESSURE |
| UNFOLIATED | TEXTURE OF SOME METAMORPHIC ROCKS IN WHICH CRYSTALS ARE NOT ARRANGED IN BANDS AND DO NOT BREAK IN LAYERS |
| SEDIMENTARY ROCK | ROCK FORMED FROM SEDIMENTS THAT HAVE BEEN PRESSED AND CEMENTED TOGETHER |
| STRATA | LAYERS OF SEDIMENTARY ROCK |
| ROCK CYCLE | CONTINUOUS CHANGING OF ROCKS FROM ONE TYPE TO ANOTHER |
| METAMORPHIC ROCK | ROCK FORMED WHEN SEDIMENTARY OR IGNEOUS ROCKS ARE CHANGED BY HEAT, PRESSURE, OR CHEMICAL REACTIONS |
| STOCK | INTRUSION SIMILAR TO A BATHOLITH THAT HAS AN EXPOSED AREA OF LESS THAN 100 SQUARE KILOMETERS |
| SILL | SHEETLIKE MASS OF IGNEOUS ROCK |
| PETROLOGIST | SCIENTIST WHO STUDIES ROCKS AND THEIR MINERAL COMPOSITION |
