An igneous rock that contains vesiclesAll of the above
As the rate of cooling increasesthe size of the crystals that form decreases
an igneous rockRhyolite
Intrusive rocksNone of these
Granite and gabbrohave similar texture
Obsidian exhibits this textureGlassy
Rocks that contain crystals that are roughly equal in size and can be identified with the unaided eye are said to exhibit this textureCoarse-grained
This igneous texture is characterized by two distinctively different crystal sizesPorphyritic
Rhyolite is the fine-grained equivalent of this igneous rockGranite
The coarse grained rock which is composed mainly of quartz and potassium feldsparGranite
This rock gets its name from a chain of mountains located in South AmericaAndesite
A popular building stoneGranite
The texture of an igneous rockrecords the rocks cooling history
igneous rock is formedby crystallization of molten rock
The most important mechanical weathering processfrost action
Chemical weathering would be most effectiveIn a warm, humid climate
NOT a product of the chemical weathering of potassium feldsparPotassium ions
NOT true about mechanical weatheringit does not affect metamorphic
NOT related to chemical weatheringfrost wedging
Influences the type and rate of weatheringMineral content, climate,& topography
Sedimentary rocksMay contain fossils, hold important clues to Earth's history, & may be economically important
Detrital sedimentary rocks are classified (named) primarily on the basis of thisParticle Size
Sedimentary rocks compose approximately this percent of Earth's outermost 10 miles5%
This rock type is associated with a high energy environment (such as a very turbulent stream)conglomerate
Pair of minerals most common in detrital sedimentary rocksclay and quartz
Detrital sediments would predominate in all of the following environments except thisSalt Flat
Compaction would probably be most significant as a lithification process for thisShale
The most abundant chemical sedimentary rockLimestone
Best describes bedded gypsum and sock saltEvaporites, chemical, sedimentary
Coal beds originate in thisfreshwater coastal swamps and bogs
Metamorphism may result from thisheat, pressure, & chemical action
A strong, parallel alignment of different mineral bands in a metamorphic rockFoliation
Changes that occur during metamorphismCertain minerals may recrystallize, the rock becomes more compact, & crystals may grow larger
The common rock produced by the metamorphism of limestoneMarble
Composed of alternating bands of light and dark silicate mineralsGneiss
The dense, nonfoliated metamorphic rock is produced most often from sand stoneQuartzite
The agents of metamorphismHeat, Pressure, and Chemical Fluids
The primary agent of contact metamorphismHeat
The metamorphic rock shale normally becomes following low grade metamorphismSlate

Bowen's reaction series predicts the sizes of the different mineral grains that grow for crystallizing magmasF
Olivine and quartz are commonly found together in the same rockF
One magma can produce several different igneous rocks having different mineral compositionsT
Basalt is the fine grained equivalent of gabbroT
Glassy igneous rocks from when magma cools too fast for mineral grains too grow.T
Quartz is quite resistant to weathering and is an important component of sands in riverbeds and on beachesT
Like most other liquids, water decreases in volume when it freezes.F
The particles in breccia are primarily silt sizedF
The most abundant sedimentary rock is shaleT
Evaporites have a biochemical origin.F
Particle size is the primary basis for distinguishing among various detrital sedimentary rocksT
Most limestone has a biochemical originT
Compaction is most significant as a lithification process for sedimentary rocks composed of sand sized particlesF
During metamorphism the material undergoing deformation remains a solidT
The single most characteristic feature of sedimentary rocks is strata, or bedsT
The largest quantity of metamorphic rock is produced by regional metamorphismT
Slate is associated with high grade metamorphismF
Metamorphism is commonly associated with mountain buildingT
Metamorphism can affect only sedimentary rocksF
coal beds
