In which set are the rock drawings labeled with their correct rock types?
The metamorphic rock at location A on the cross section shown is most likely
marble
quartzite
slate
phyllite
The three statements below are observations of the same rock sample:
• The rock has intergrown crystals from 2 to 3 millimeters in diameter.
• The minerals in the rock are gray feldspar, green olivine, green pyroxene, and black amphibole.
• There are no visible gas pockets in the rock.
This rock sample is most likely
granite
sandstone
phyllite
gabbro
Drawings of six sedimentary rocks labeled A through F are shown below.
Which table below shows the rocks in the drawings correctly classified by texture?
According to the Earth Science Reference Tables, if granite were subjected to intense heat and pressure, it would most likely change to
conglomerate
gneiss
basalt
sandstone
Which conclusion about graphite and diamond is best supported by these diagrams?
They have a similar color because of their similar compositions.
They have similar crystal shapes because of their similar compositions.
They have different chemical compositions due to the difference in their atomic arrangements.
They have different physical properties due to the difference in their atomic arrangements.
Which mineral property is being tested?
luster
fracture
streak
density
The classification system in the table above was mostly based on the
way in which the rock formed
color of the rock
size of the crystals in the rock
age of the minerals in the rock
Based in the info in the "Igneous Rock" Table, what rock is Letter B?
Gabbro
Granite
Rhyolite
Basalt
Which rock is represented by sample C?
Limestone
Granite
Gneiss
Rhyolite
Analysis of rock D shows that it is composed of the minerals quartz, feldspar, hornblende, and biotite
mica. Rock D is probably
gabbro
granite
rhyolite
basalt
Which processes most likely formed rock F?
faulting and volcanic activity
melting and solidification
heating and application of pressure
burial and cementation
Metamorphic rocks are formed by
erosion and deposition
melting and solidification
heating and pressure
compaction and cementation
Which inference is best supported by the evidence shown in the diagram?
Contact metamorphism occurred when the igneous rock was in its molten state.
Sandstone formed after sand was deposited on top of the metamorphic rock.
Igneous rock was changed to sedimentary rock.
Shale formed from the melting and solidification of the sandstone layer.
Which characteristic is represented by letter A in the "Metamorphic Rocks" table?
particles rounded and cemented together
clastic
nonfoliated
porous and permeable
What causes rocks to break down? (Typically by wind or water)
Weathering
Erosion
Deposition
Cementation
When sediments bind together through the crystilization of minerals
cementation
compaction
deposition
erosion
Pieces of rock, sand and other materials that have been weathered and eroded are called
small bits
sand
sediments
dirt
What are clastic rocks?
Compacted sediment (rocks, sand)
Magma made the rock
The rock has crystals
made from organic materials
Sedimentary rocks are formed by
Cooling of lava or magma
Heat and pressure
Compacting and cementing of other stuff
What type of metamorphism caused the formation of Phyllite?
Contact
Regional
