|---|
| cementation and compaction | processes to form sedimentary rock |
| heat, pressure and hydrothermal solutions | agents of metamorphism |
| Iron and Nickel | Elements believed to make up Earth's core |
| Halides, sulfates, carbonates, silicates, oxides, sulfides | major mineral groups |
| Igneous, metamorphic, and sedimentary | The three major rock types |
| sediment | end result of weathering and erosion |
| Oxygen, silicon, aluminum, iron, and calcium | FIve most abundant elements in the crust |
| melting and cooling | igneous processes |
| inner core | densist layer of the earth |
| Slate | Rock metamorphisized from Shale |
| Characteristics of minerals | naturally occuring, solid, inorganic, organized chrystals, defined chem. compostion |
| Rock cycle | Includes many ways rocks form, break down and reform |
| Oxygen | Most abundant element in Crust |
| Outer core | liquid layer beleved responsible for magnetic field |
| Intrusive igneous | Igneous rock formed at depth |
| Extrusive igneous | Igneous rock formed at the surface |
| radioactive decay and energy from Earth's formation | powers igneous rock formation |
| lithosphere | composed of Crust and upper mantle |
| crystal size | determined by cooling rate |
| fossil | imprint of ancient plant preserved in rock |
| foliation | arrangement of crystals into wavy or parallel bands |
| sedimentary | most common rock type at surface |
