  7. What is Sedimentary Rock? • How does it form? Sediment (rock pieces and soil) is compacted or squeezed into rock • What does it look like? Layers, Porous, often contains fossils Examples: Chalk, limestone, sandstone

  8. What is Metamorphic Rock? • How does it form? Many rocks are squeezed by pressure & heat, forming new rocks. • Deposition: Rocks/Soil is deposited. • Compaction: Rock/Soil is pushed together. • Cementation: Compacted rock is heated.

  9. What is Metamorphic Rock? • What does it look like? Bands/Stripes of light and dark, Crystals • Examples: Marble, slate
