Which of the following is an example of a mineral? a) concrete b) steel c) quartz d) coal
What is quartz?
100
A class of igneous rock formed when magma cools deep below the earth's crust.
What is an intrusive igneous rock?
100
A sedimentary rock that is formed from the remains of living things.
What is an organic sedimentary rock?
100
Metamorphic rocks are classified according to this texture characteristic.
What is foliation?
100
The parent material for ALL rocks.
What is magma?
200
The most common magnetic mineral.
What is magnetite?
200
This igneous intrusion forms the core of many major mountain ranges.
What is a batholith?
200
This sedimentary rock is formed from cemented, rounded pebbles.
What is a conglomerate?
200
Quartzite and marble are examples of this classification of metamorphic rock.
What is nonfoliated?
200
The term used to describe the luster of a diamond.
What is brilliant?
300
The properties of a mineral are primarily a result of its a) hardness b) cleavage or fracture c) density d) chemical composition
What is chemical composition?
300
This structure is formed when magma flows out through cracks in the earth's surface and spreads out over a large area.
What is a lava plateau?
300
Gypsum and halite are this type of sedimentary rock.
What is chemical?
300
A change in the structure and mineral composition of rock surrounding an igneous intrusion.
What is contact metamorphism?
300
A sheet of hardened magma that forms between and parallel to layers of rock.
What is a sill?
400
A mineral in which all atoms are bonded tightly together will most likely be a) hard b) metallic c) dense d) magnetic
What is hard?
400
An igneous intrusion that cuts across rock layers.
What is a dike?
400
Fragments that result from the breaking of rocks, mineral, and organic matter.
What is sediment?
400
The changing of rock over several hundred square kilometers by pressure of colliding tectonic plates.
What is regional metamorphism?
400
A flat-bottomed intrusion that pushes over-lying rock into an arc and can form dome-shaped mountains.
What is a laccolith?
500
This is the number of oxygen atoms in a silicon-oxygen tetrahedron.
What is FOUR?
500
Which of the following is an igneous rock? a) limestone b) gypsum c) gneiss d) basalt
What is basalt?
500
The TWO processes responsible for turning sediments into sedimentary rock.
What are cementation and compaction?
500
Metamorphism results from these three conditions.
What are heat, pressure, and chemical processes?
500
These are the three basic types of rock.
What are igneous, sedimentary, and metamorphic?
