These two minerals are commercial sources of iron.
What are hematite and magnetite?
Arrow A leads to the formation of this type of rock.
What is sedimentary?
These two processes lead directly to the formation of igneous rock.
What are melting and solidification?
These two processes produced rock layer B.
What is compaction and cementation?
Describe the geologic process that is occurring to cause this conversion.
What is metamorphism?
This physical property, showing how the mineral breaks, is most easily seen in the photograph.
What is cleavage?
Arrow B leads to the formation of this type of rock.
What is igneous?
This term describes the observable characteristic that best describes the rock in the picture.
What is vesicular (or gas pockets)?
This mineral precipitates from oceans and forms rock salt.
What is halite?
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?
Arrow C leads to the formation of this type of rock.
What is metamorphic rock?
This fine-grained, dark-colored, igneous rock is most likely
What is basalt?
This term describes rocks that form from fragmental rock particles that are cemented together.
What is clastic?
Most marble is composed primarily of this mineral.
This dark red mineral is commonly used as an abrasive and is the NYS Gemstone.
What is garnet?
These type(s) of rocks can be the source of deposited sediments.
What are sedimentary, igneous and metamorphic?
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?
This rock, shown in the picture, contains rounded pebbles that have been cemented together.
What is conglomerate?
Heat and pressure cause this parent rock to change into quartzite.
What is sandstone?
This element, found in both biotite mica and muscovite mica, makes up the greatest percent by volume of Earth's crust.
What is oxygen?
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?
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?
This sedimentary rock is formed by the compaction and cementation of sorted sediments 0.008 centimeters in diameter.
What is sandstone?
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?
