Metamorphic Rock Practice:

The recrystallization of unmelted material under high temperature and pressure results in

• metamorphic

• sedimentary

• igneous rock

• volcanic rock

Where is metamorphic rock frequently found?

• on mountaintops that have horizontal layers containing marine fossils

• within large lava flows

• as a thin surface layer covering huge areas of the continents

• along the interface between igneous intrusions and sedimentary bedrock

Which nonfoliated rock forms only in a zone of contact metamorphism?

• conglomerate

• hornfels

• pegmatite

• quartzite

Which physical characteristic best describes the rock phyllite?

• glassy texture with gas pockets

• clastic texture with angular fragments

• bioclastic texture with cemented shell fragments

• foliated texture with microscopic mica crystals

The cartoon presents a humorous look at history. What kind of rock does the complaining rock collector want?

• felsic volcanic rocks

• clastic sedimentary rocks

• inorganic sedimentary rocks

• regionally metamorphosed rocks

During the Permian Period, sedimentary bedrock in the Appalachian Region was subjected to high temperature and pressure. Calcite deposits that had existed in this environment would most likely have formed

• schist

• gabbro

• marble

• gneiss

Which sequence of change in rock type occurs as shale is subjected to increasing heat and pressure?

• shale --> schist --> phyllite --> slate --> gneiss

• shale --> slate --> phyllite --> schist --> gneiss

• shale --> gneiss --> phyllite --> slate --> schist

• shale --> gneiss --> phyllite --> schist --> slate

How do the metamorphic rocks schist and quartzite differ?

• Quartzite contains the mineral quartz and schist does not.

• Quartzite forms from regional metamorphism and schist does not.

• Schist is organically formed and quartzite is not.

• Schist is foliated and quartzite is not

The diagram shows four rock samples. Which sample best shows the physical properties normally associated with regional metamorphism?

• A

• B

• C

• D

The diagrams show how planet materials are changed into the three forms of coal by natural processes. By which process is anthracite coal formed from bituminous coal?

• solidification

• deposition

• metamorphism

• intrusion
