FC: Alex and Avery's book of rocks and minerals
1: Rock Types | Sedimentary Igneous Metamorphic
2: Sedimentary | Sandstone is an example. It forms when layers of sediment compact together. It can be transformed into an igneous rock by melting then hardening. www.geology.com for sedimentary rock examples.
3: Igneous | Granite is an example. It is formed when magma cools and hardens. Heat and pressure melts it and forms metamorphic rock. www.geology.com for examples of igneous rocks.
4: Metamorphic | An example of metamorphic rock is gneiss Metamorphic rocks have been modified by heat, pressure and chemical process usually while buried deep below Earth's surface. It transforms into sedimentary rock by weathering and erosion Examples are found at www.geology.com
5: Mineral Types | Silicates Non-silicates
6: Silicates | Examples of silicate minerals are Topaz and Serpentine the structure is composed of isolated tetrahedrons, it is composed of Silicon and Oxygen Make up 90% of earth's crust, tetrahedrons combine forming frameworks, sheets, and chains www.visionlearning.com
7: Non-Silicates | Examples of non-silicates are gold, silver, and copper. non-silicates display a wide range of crystalline structures. Non-silicates are split into 6 sub-groups, carbonates, oxides, sulfides, halides, sulfates, and native metals. http://www.archaeology.ncdcr.gov/ncarch/GeoArcheo/MineralsA.htm
