B) Are chemically active solutions, not pure water C) Can be derived from groundwater or magma, or can be the product of metamorphic reactions D) Change a rock's chemical composition, a process known as exhumation. Which of the following statements is False? A metamorphic rock...(B) - ANSWERSA) May develop a texture of interlocking grains B) Cannot be formed bel...

Marble is a metamorphic rock that forms from a __________ protolith? - ANSWERSlimestone Which of the following processes will cause metamorphism? - ANSWERSan increase in pressure, interaction with hydrothermal fluids, an increase in temperature (all) What is metasomatism - ANSWERSa change in the bulk composition of a rock during metamorphism Where does sea floor metamorphism take place? - ANSWERSin close proximity to mid-ocean spreading centers What is the relation between metamorphi...

Metamorphism typically occurs ________. - ANSWERSdeep beneath Earth's surface The metamorphic grade refers to ________. - ANSWERSthe degree to which the parent rock changes during metamorphism How can a rock change during metamorphism? - ANSWERSMetamorphism can change the mineralogy, texture, and/or chemical composition of a rock. What kinds of rocks can become metamorphic rocks? Choose all that apply. - ANSWERSmetamorphic rocks igneous rocks sedimentary rocks What is meant by t...

Metamorphism - ANSWERSchanges in heat, pressure, and the chemical environment of rocks geothermal gradient - ANSWERStemperature increases with depth (pressure) Geobaric gradient - ANSWERSpressure increases with depth -"normal" geobaric gradient~300-400 bar/km confining - ANSWERSuniform directed pressure - ANSWERStension, compression, shear Metasomatism - ANSWERSmineral reactions due to fluids Shock metamorphism - ANSWERSmeteorite Sea floor metamorphism - ANSWERSoccurs...

metamorphic rocks - ANSWERSrocks changed from one form to another by intense heat, intense pressure, or the action of watery hot fluids parent rock - ANSWERSthe rock type that was metamorphosed. parent rocks can be any of the three main rock types: igneous rocks, sedimentary rock, or even metamorphic rock sedimentary conglomerate, sandstone, and limestone - ANSWERSmetaconglomerate, quartzite, and marble shale - ANSWERSslate, phyllite, schist, and gneiss hornfels - ANSWERSformed only ...

metamorphic - ANSWERS"of changed form" metamorphic rocks - ANSWERSrocks changed from one form to another by intense heat, intense pressure, or the action of hyrdothermal fluids protolith - ANSWERSparent rock: the rock type that was metamorphosed ie: igneous, sedimentary, metamorphic metamorphic grade - ANSWERSthe intensity of metamorphism from low grade (least intense) to high grade (most intense) serentinite - ANSWERSmetamorphosed from mafic and ultramafic igneous rocks met...

A rock experienced melting then cooling, burial to deep depths during mountain building, and then uplift and weathering. Which pathway did this rock take through the rock cycle? - ANSWERSIgneous → metamorphic → sedimentary A rock high in slate and chlorite is likely a(n) - ANSWERSlow-grade metamorphic rock. As they pass through the rock cycle, all atoms - ANSWERSdo not move through the rock cycle at the same rate. During metamorphism, the process that changes the crystal structure o...

Foliation - ANSWERS* Planes of minerals formed in response to stress * A feature of many metamorphic rocks * crystals rearrange into layered planes depending on the type and orientation of the stress during metamorphism Foliation planes are recognized by: - ANSWERS* The preferred orientation of minerals * alternating bands of different minerals * the flattening and stretching of minerals * foliation forms by physical rotation of preexisting minerals Non-foliated rocks are named primarily a...

Compared to low-grade metamorphic rocks, high-grade rocks _____. (a.) always contain more quartz and feldspar (b.) are produced closer to the surface, high in the stratigraphic column (c.) are produced at greater temperatures and pressures (d.) are produced at cooler temperatures, but greater pressures - ANSWERS(c.) are produced at greater temperatures and pressures Two common metamorphic rocks that typically lack foliation are _____. (a.) slate and phyllite (b.) gneiss and migmatite (c....

When does metamorphism occur? What does metamorphism include? Meta. rocks compare to Ig. and Sed. rocks? Does Metamorphism have a solid/not solid state? What are these two types of changes? - ANSWERSOccurs at elevated temperature and pressure, typically at the base of mountains Includes Recrystallization, making new minerals from original minerals, and sometimes, changes in the texture of the Parent Rock (protolith). Metamorphic rocks are organized compared to Igneous and Sedim...
