Geology Chapter 1.6 0.0 / 5 ? Geologyclassification of rocksASOCR Created by: abbbywCreated on: 23-12-17 11:33 Diagenesis includes all processes that occur in sediments at low temperature + pressure at or near earth's surface 1 of 19 Metamorphism the changing of rocks in the Earth's crust by heat / pressure / volatile content. It's isochemical + occurs in solid state 2 of 19 Igneous rock a rock that has crystallised from a magma 3 of 19 Metamorphic rock formed by the re crystallisation of other rocks in solid state due to pressure / temperature 4 of 19 Partial melting occurs when only a portion of rock in the lower crust or upper mantle is melted 5 of 19 Recrystallisation is the solid state process that changes minerals into new crystalline metamorphic minerals 6 of 19 Crystallisation occurs during the cooling of magma / lava so that solid mineral crystals form 7 of 19 Burial occurs when sediment is covered by younger layers of sediment 8 of 19 Sedimentary rock a rock composed of fragments that have been deposited compacted + cemented 9 of 19 Clast a fragment of broken rock produced by mechanical weathering + erosion 10 of 19 magma accumulation magma collecting within a magma chamber 11 of 19 intrusions composed of igneous rock formed below the earth's surface, where magma is forced into pre-existing rocks 12 of 19 extrusion the emission of magma onto the earth's surface where it forms a lava flow 13 of 19 foliation a texture in metamorphic rocks formed by the preferred alignment of flat / tabular minerals 14 of 19 deposition the laying down of sediment that occurs when a transporting agent loses energy 15 of 19 weathering the breakdown of rocks in situ 16 of 19 erosion the removal of weathered material, usually by the physical action of transported fragments 17 of 19 transport the means by which weathered material is moved from 1 place to another by water, wind ice or gravity 18 of 19 uplift the return of buried rocks to the Earth's surface by tectonic forces 19 of 19
