These two processes lead directly to the formation of igneous rock.
What are melting and solidification?
100
These two processes produced rock layer B.
What is compaction and cementation?
100
Describe the geologic process that is occurring to cause this conversion.
What is metamorphism?
200
This physical property, showing how the mineral breaks, is most easily seen in the photograph.
What is cleavage?
200
Arrow B leads to the formation of this type of rock.
What is igneous?
200
This term describes the observable characteristic that best describes the rock in the picture.
What is vesicular (or gas pockets)?
200
This mineral precipitates from oceans and forms rock salt.
What is halite?
200
The two geologic processes that are most likely responsible for the banding and alignment of mineral crystals represented in the diagram are...
What are heat and pressure?

Quartz and halite have different crystal shapes primarily because
What is the internal arrangement of the atoms?
300
Arrow C leads to the formation of this type of rock.
What is metamorphic rock?
300
This fine-grained, dark-colored, igneous rock is most likely 
What is basalt?
300
This term describes rocks that form from fragmental rock particles that are cemented together.
What is clastic?
300
Most marble is composed primarily of this mineral.
What is calcite?
400
This dark red mineral is commonly used as an abrasive and is the NYS Gemstone.
What is garnet?
400
These type(s) of rocks can be the source of deposited sediments.
What are sedimentary, igneous and metamorphic?
400
The bedrock of the flat areas on the Moon is mostly basalt. Describe the formation of this fine-grained igneous rock. (You must use the term "rapid" or "slow" in your description.
What is the rapid cooling of molten rock?
400
This rock, shown in the picture, contains rounded pebbles that have been cemented together.
What is conglomerate?
400
Heat and pressure cause this parent rock to change into quartzite.
What is sandstone?
500
This element, found in both biotite mica and muscovite mica, makes up the greatest percent by volume of Earth's crust.
What is oxygen?
500
State the name of one metamorphic rock that most likely formed in the zone of contact metamorphism between rock unit A and the basalt.
What is marble?
500
The four igneous rocks below are classified into two groups.
This is the basis for the classification of the rocks above.
What is crystal size?
500
This sedimentary rock is formed by the compaction and cementation of sorted sediments 0.008 centimeters in diameter.
What is sandstone?
500
This rock is composed of mica, quartz, feldspar, amphibole, garnet and sometimes pyroxene. It displays platy mica crystals from the metamorphism of clay and feldspars.
What is schist?
