Rock Cycle

Before the student can select either path (a) or

path (b) at choice 1, the student must make a

decision about

• mineral composition

• crystal size

• the temperature at which rocks form

• the appearance of the rock grains

Which processes would form the type of rock that

is represented by circle B?

• deposition and compaction

• weathering and erosion

• melting and solidification

• faulting and folding

In the simple rock-cycle diagram, which process

along path X would change the schist (stage C)

directly into a pile of sediments (stage A)?

• uplift, weathering, and erosion of schist

• cementing of sediment grains followed by

  compaction

• melting of the schist followed by cooling

• heat and/or pressure applied to the schis

The diagram shows a cross section of a

portion of Earth's crust that has undergone

geological processes. Overturning of rock

layers has not occurred. Point A represents

one location of metamorphic rock.

As magma cools, what process changes it into

basalt?

Rocks can be classified as sedimentary, igneous,

or metamorphic based primarily upon di erences

in their

• color

• density

• origin

• age

Rocks are classified as igneous, sedimentary, or

metamorphic based primarily on their

• texture

• crystal or grain size

• method of formation

• mineral composition

Mineral crystals of quartz, biotite mica, and

amphibole are produced primarily by the

• chemical reaction of elements in seawater

• cooling and solidi cation of magma

• deposition of sediments by a glacier

• metamorphism of bituminous coal

The photographs below show samples of two

different rocks, labeled A and B. The arrow

represents the process by which a rock like rock A

can change into a rock like rock B.

Which process does the arrow represent?

• metamorphism

• erosion

• melting

• cementation

The boxes labeled A through G

represent rocks and rock materials. Arrows

represent the processes of the rock cycle.

Which lettered box could represent the rock

conglomerate?

• E

• G

• C

• D
