Ch 3 Quiz
Which letter in this classification table indicates the position of rhyolite?
B
Which letter in this classification table indicates the position of basalt?
E
Carbonate rocks exposed at the surface in wet environments will
dissolve and weather readily.
A type of rock that forms directly from precipitates of hot water is called a(n)
hydrothermal rock.
Rock that has formed from cooling magma or lava is
igneous rock.
Heat, pressure, and deformation are processes that can create
metamorphic rocks.
Which of the following is NOT involved in turning some sediment into sedimentary rock?
metamorphism
What type of metamorphism would occur in this setting?
regional metamorphism
A finely crystalline or glassy igneous texture indicates that
the rock cooled quickly.
What texture is displayed by the igneous rock in this photograph?
vesicles
The natural sediments that hold clasts together precipitate in the empty pore spaces after compaction. Those precipitates come from
water containing dissolved materials.
The uniformly-sized sand shown here would be described as
well sorted.
Which letter in this classification table indicates the position of granite?
A
Which of the following is true of igneous landscapes?
Columnar jointing is common in basaltic lava flows.
Which letter in this classification table indicates the position of gabbro?
D
The effect of transportation on a pebble's particle size is best summarized by which statement?
Its size decreases.
What can you infer from this contact between an overlying conglomerate and underlying sandstone?
There was an abrupt event, such as a flood.
What is the best explanation for the shape of these clasts?
They have been transported a significant distance.
If a rock is poorly sorted, this means the rock contains
a wide range in the size of clasts.
Which of the following igneous rocks would be formed by the slowest cooling?
coarse granite
What type of metamorphism would occur in this setting?
contact metamorphism
Which of the following does NOT help define foliation in metamorphic rocks?
crystals that grow in a random orientation
Which of the following locations would contain mud and the remains of small creatures?
location 5, on a relatively deep seafloor
If rock is exposed to enough heat after metamorphism it will eventually
melt into magma.
The rock cycle was conceived by James Hutton in an attempt to explain how
older rocks become new sediment.
Which of the following is NOT a common type of cement in sedimentary rocks?
pyroxene
Clastic sedimentary rocks are classified primarily on the basis of
sediment size
Which of the following is NOT a typical environment in which a metamorphic rock forms?
solidification of lava
Which of the following situations would result in angular clasts?
steep slopes in a mountain
The main difference between conglomerate and breccia is
the shape of the clasts.
A vesicular igneous texture indicates that
there was a lot of gas in the magma.
