Analytic Thinking SkillsTypes of Rock
Geologists divide rocks into three main classes according to how they form. All igneous rocks form when molten material cools and hardens, and all basalt is igneous rock. Sandstone and limestone are sedimentary rocks, and every sedimentary rock forms in layers. Most sandstone is made mainly of quartz grains. No metamorphic rock forms directly from molten material. Marble is a metamorphic rock that forms when limestone is changed by heat and pressure, and although most marble is white or gray, some is pink or green.
