4. Science Starter Ppt Answers: 1.Igneous-has random, interlocking crystals 2.Sedimentary-has rocky fragments cemented 3.Metamorphic-has flattened & aligned crystals 4.Clastic -has rocky fragments cemented together 5.Organic -contains shells of once living organisms 6.Intrusive -has large &random, interlocking crystals 7.Foliated -has aligned crystals producing layers 8.Extrusive - has gas bubbles preserved from fast cooling 9.Non-foliated -has flattened grains, not arranged/aligned
