Question Answer
Foliation metamorphism by combing (pressure)
Deposition the process of sediment dropping out of the current and no longer being transported
lithification converting sediment to rock by compaction and cementation
clasts products of weathering
sediments pieces of solid material that have been deposited on the earth's surface by wind, water, ice, gravity, and precipitation
detrial sedimentary rocks composed of clasts and parent material
chemical sedimentary rocks made of ions that precipitate out of solution
biological sedimentary formed from living/dead things
low grade metamorphism can still identify what the parent material is
high grade metamorphism the rock has been altered so you can not identify the parent material
What are the stages of the rock cycle? Melting, cooling, weathering, lithification, metamorphing
erosion transport of the products of weathering high transportrate
extrusive cools quickly
intrusive cools slowly
amorphic crystaline structure without shape
metamorphic rock the parent rock is changed by exposure to high temperature, high pressure, or both; made by heat and pressure
Earth's layers? Inner core, outer core, lower mantle, upper mantle, asthenosphere, lithosphere, continental crust, oceanic crust
Characteristics of slate? fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism
Characteristics of schist? Grain size – fine to medium grained; can often see crystals with the naked eye. Color – variable – often alternating lighter and darker bands, often shiny.
Characteristics of gneiss? Gneiss is a medium- to coarse-grained, semischistose metamorphic rock. It is characterized by alternating light and dark bands differing in mineral composition
Characteristics of marble? Image result for characteristics of marble
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
