This is the softest mineral on the Moh’s Hardness scale.

What is talc?

This mineral is commonly found in teeth and bones.

What is apatite?

This is the most common carbonate mineral.

What is calcite?

This is the long version definition of a mineral.(Hint – 5 things)

What is a naturally occurring, inorganic, solid with a definite crystal structure, and chemical

composition.

This is the correct order of the Moh’s Hardness scale.

What is talc, gypsum, calcite, fluorite, apatite, feldspar,quartz, topaz, corundum, and diamond.

These seven characteristics are generally used to identify minerals.

What are color, luster, streak, cleavage/fracture, specific gravity, hardness, and crystal structure.

This crystal structure has 3 equal axes all at right angles.

What is isometric?

This crystal structure is described as 3 axes of unequallength, all at right angles to each other.

What is orthorhombic?

This crystal structure has three unequal axes that are all oblique to each other.

What is triclinic?

Quartz has this type of crystal structure.

What is hexagonal?

Galena has this type of crystal structure.

What is isometric (cubic)?

Chalcopyrite has this type of crystal structure.

What is tetragonal?

This type of texture results from slow-cooling of magma.

What is phaneritic?

This is the largest type of intrusive body of magma.

What is a batholith?

This is a general description of igneous intrusions that runs parallel to the rock layers they cut through.

What is concordant?

This is an example of a dark brown vesicular volcanic rock.

What is scoria?

Granite is this type of igneous rock. (two terms)

What is felsic plutonic?

Gabbro is an example of this type of igneous rock. (2 terms)

What is a mafic plutonic rock?

Water, wind, ice, and gravity.

What are ways sediments may be transported?

Biogenic (or organic)

What is sediment composed of the fossilized remains of plants or animals?

Sand

What is clastic sediment?

Well-sorted

What is a wide range of sediment size?

Graded bedding

What is sorted sediment “graded” in size, upward from coarse to fine?

Stratification

What is the overall process of creatingsedimentary rocks?

Limestone will metamorphose into this rock.

What is marble?

Protolith

What is the pre-existing rock before metamorphism occurs?

Contact metamorphism

What is the result of igneous intrusions into surrounding rock?

Temperature, pressure, and chemically active fluids.

What are the three primary agents for metamorphism?

Slatey, phyllitic, schitose, and gneissic

What are types of foliation?

The parent rock of gneiss.

What is granite?
