  3. 3. How is the rock formed The rocks start out as Igneous, or Sedimentary Rocks, and change under tons, tons of pressure that forces heat to build up and changes into Metamorphic Rock. Characteristics of the rock Regularly aligned crystals, may be shiny or hard. Sometimes flake into layers, and large grains. klumnknknj Common rocks limestone, gneiss, sandstone, granite, gypsum, conglomerate Granite Rock Hounds Conglomerate Rock Hounds Metamorphic BY Morgan
  4. 4. Igneaus How is this rock formed? From casing the magma to rise deep with in the earth becomes trapped in small pockets What are some of the characteristics of this rock ? The presence of vesicules Choles in extrusive igneous rock may be dark colors and heavy. Common Rock Granite, Basalt, Obsidian, Pumice Scoria Rock Hounds Granite Rock Hounds By . Katelyn
  5. 5. How is this rock formed These little bits of our earth are washed downstream were they settle to the bottom of the rivers ,lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time until the bottom layers slowly turn into rock. Sedimentary Common rocks of this type Conglomerate, Gneiss, Granite, Gypsum, Limestone, Obsidian ,Pumice Sandstone, Shale. Grains cemented together. The presence of fossils. Light colored & light weight. May display interlocking grains but is very light weight. BY: TAYLOR Limestone from rock Hounds Shale from rock hounds Characteristics
  6. 6. Conclusion We have come to the Conclusion that are rock is a Igneous rock. The presence of holes Choles In extursive in Igneous rock Dark colors and maybe heavy.
