In regional metamorphism the source of increased temperature and pressure is a local intrusive heat source false impact metamorphism false the increase in temperature with increasing depth of burial true due to increased rate of radioactive decay false Single A Geologist suffers from a black eye after yelling "Gneiss!!!" to a classmate, who happened to be sunning on a large boulder. The geologist really meant to tell the classmate that the rock they were laying on would fizz with the application of acid false is commonly used in billiard table construction false demonstrates schistosity false is a high-grade, silicate-rich, mineralogically banded metamorphic rock true Single A combination of shallow earthquakes, tension, and contact metamorphism characterizes transform fault margins false spreading centers true continent/continent margins false subduction type margins false Single Marble is a metamorphic rock that forms from a ___________ parent. granite false limestone true sandstone false shale false Single The pressure and heat that drive metamorphism result from which three forces? The internal heat of the Earth, the weight of overlying rocks, and horizontal pressures developed as rocks become deformed true The weight of the overlying rocks, solar heating, and nuclear fusion false Horizontal pressures developed as rocks deform, bonding, heat released during crystallization false Internal heat of the Earth, nuclear fission, heat released during chemical weathering false Single Which type of pressure will result in the alignment of metamorphic minerals? Contact pressure false Directed pressure true Confining pressure false Chemical pressure false Single During metamorphism, changes in the bulk composition of a rock occur primarily as a result of increases in pressure false increases in temperature false reaction with hydrothermal fluids true all of these false Single What type of metamorphism is caused by high temperature and high pressure imposed over a large volume of crust? burial false contact false regional true cataclastic false Single A rock that has undergone cataclastic metamorphism would most likely display which of the following? preserved sedimentary layering false pulverized rock fragments true new minerals false large olivine crystals false Single Which of the following statements about metamorphism of a shale is false? with increasing metamorphism, the clay minerals breakdown to form micas false with increasing metamorphism, the grain size of the minerals gets smaller true with increasing metamorphism, foliation develops false with increasing metamorphism, the amount of water decreases false Single
