Rocks • Minerals combine to form rocks • There are three types of rocks • Igneous • Sedimentary • Metamorphic
Igneous Rock Igneous forms when hot, liquid rock, or magma, cools and hardens Igneous rock formed on the surface is called extrusive Rock formed under surface is intrusive
Sedimentary Rocks Sedimentary rocks are formed from compaction and sedimentation Sedimentary contain layers called strata
Metamorphic Rock Metamorphic rock is formed by heat and pressure
