Across
- 4. the series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geological
- 6. rock that forms when magma cools and solidfies
- 7. a change in the texture, structure,or chemical composition of a rock due to contact with magma
- 10. rock that forms from the cooling and solidification of lava at earth's surface
- 11. describes magma or igneous rock that is rich in magnesium and iron and that is generally dark in color
- 13. the metamorphic rock texture in which mineral grains are not arranged in plains or bands
- 14. the process in which minerlas precipitate into pore spaces between sediment grains and bind sediments together to form rock
- 16. rock formed from the cooling and solidification of magma beneath earth's surface
Down
- 1. a change in the texture, structure, or chemical composition of a rock due to changes in temperature and pressure over a large area, generally as a result of tectonic forces
- 2. sedimentary rock that forms from the remains of plants or animals
- 3. the simplified pattern that illustrates the order in which minerals crystallize from cooling magma according to their chemical composition and melting point
- 5. forms from minerals that were once dissolved in water
- 7. sedimentary rock that forms when fragments of preexisting rocks are compacted or semented together
- 8. describes magma or igneous rock that is rich in feldspars and silica and that is generally light in color
- 9. the process in which the volume and porosity of a sediment is decreased by the weight of overlying sediments as a result of burial beneath other sediments
- 12. the metamorphic rock texture in which mineral grains are arranged in plains or bands
- 15. the process in which one type of rock changes into metamorphic rock because of chemical processes or changes in temperature and pressure
