2. Story in the Rocks By Charlotte Prior Rachel Deal Anthony Perkins

3. Igneous Rocks  Igneous rocks are rocks that are formed either under ground or above ground  Under ground igneous rocks are forms when magma deep within the earth cool and form intrusive igneous rocks  Extrusive igneous rocks are formed when magma comes to the surface and becomes lave then cools and hardens to form extrusive igneous rocks IGNEOUS ROCK-Rock formed by solidification of molten magma.  http://www.education.usgs.gov/schoolyard http://www.education.usgs.gov/schoolyard

4. Metamorphic Rocks  Metamorphic rocks are types of rocks that change into a different rock.  These rocks are subjected to heat and pressure.  From the heat and pressure the rocks completely change underground. http://www.education.usgs.gov/schoolyard

5. Sedimentary Rocks  Sedimentary rocks are rocks that are made up of pieces of earth that have eroded and deposited over thousands of years  The sediment form layers and then the bottom layers get pressed together and form sedimentary rocks  http://www.education.usgs.gov/schoolyard http://www.education.usgs.gov/schoolyard

6. Rock Cycle  The rock cycle is the formation, breakdown, and reformation of rocks as a result of sedimentary, igneous, and metamorphic processes.  For rocks to change they go through weather and erosion, heat and pressure, deposition, and cooling and crystallization WEATHERING-The basic chemical process that causes exposed rock to decompose. EROSION-The process by which the surface of the earth is worn away by the action of water, wind, ect. DEPOSITION-The state of being deposited by water, air, or ice. http://imnh.isu.edu/digitalatlas

7. Fossils  Fossils are preserved remains or traces of plants, animals, and organisms from the remote past that have turned into stone  Fossils form in sedimentary rock because the plants, animals, and organisms get traped between the layers of sediment that form over thousands of years  http://www.enchantedlearning.com/subjects/ geology http://www.enchantedlearning.com/subjects/ geology

8. Geological Time Scale  Extensive internal of time occupied by the earth.  This is a way to tell what happened to the earth thousands of years ago.  Rock, fossils, ect. Tell what happened GEOLOGIC TIME SCALE-Standard method to divide the earth’s long natural history into manageable parts. http://en.wikipedia.org/wiki/time

9. Superposition A key axiom based on observations of natural history that is a foundational principle of sedimentary stratigraphy and so of other geology dependant natural sciences LAW OF SUPERPOSITION-A basic law of geochronology, stating that the youngest laying of rock is on top. http://en.wkikipedia.org/wiki/law
