2: Igneous Rock | How is it formed? When magma, or molten rock, cools and hardens. | How it can be transformed? Changing temperature and pressure.
3: three common example. 1. Granite 2. Obsidian 3. Gabbro
4: Sedimentary Rock | How is it formed? sediment deposits are compressed, cemented together, and harden. | How can it be transformed? melting & cooling becomes igneous.
5: Examples: Breccia, Chert, and Coal
6: Metamorphic Rocks | How is it formed? Sediment deposits are compressed, cemented together, and harden.
7: How can it be transformed? Erosion, deposition, and cementation becomes sedimentary | Examples: Amphibolite, Gneiss, and Marble
8: Silicates | Chemical composition: Combination of silicon and oxygen, also may contain 1 or more metals. | Structure- silicon-oxygen tetrahedron: Silicon ions bonded and surrounded by 4 oxygen ions.
9: Quartz Feldspars Olivine Micas Beryl
10: Non-Silicate | Chemical composition: silicon, oxygen, and other elements. | characteristics: Benitoite, beryl, amphibole. | examples: Ice structure and diamond structure.
12: Compaction & Cementation | Occurs: When a rock eroded down to sediment and either crushed into rock or chemically turned into a rock.
14: Melting & Cooling | Occurs: Rock is melted and it cools into magma, then cools and becomes igneous rocks either intrusive or extrusive.
16: Heating & Pressure | Occurs: formation process of a low pressure area is known as cyclogenesis.
