Rock Cycle

Before the student can select either path (a) or

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

decision about

Which processes would form the type of rock that

is represented by circle B?

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)?

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?

(a)  

Rocks can be classified as sedimentary, igneous,

or metamorphic based primarily upon di erences

Rocks are classified as igneous, sedimentary, or

Mineral crystals of quartz, biotite mica, and

amphibole are produced primarily by the

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?

In which set are the rock drawings labeled with

their correct rock types?
