B.

It
in
creases as its form changes

the amount of rock 50 million years from now will be

the

the current
amounts.
What evidence could
be

site
d

for
the
previous claim?

A.

The total amount of rock on Earth fluctuates greatly.

B.

The total amount of rock on Earth appears to be constant.

C.

The amount of sedimentary rock increases while the amount o
f metamorphic rock decreases.

D.

The amount of igneous rock increases while the amount of sedimentary rock decreases.


12.
T
he amount of rock on the earth remains fairly constant
,

yet

the amount of

lava

and magma
fluctuates. What is the
BEST

possible explana
tion
?



A. The amount of lava

released is so minimal that it
cannot be recorded
.


B.

The
lava is quickly eroded and so does not stay as a rock long enough to be
recorded
.


C.

Rock is
contently

being melted and turned back into magma.



D. Intrusive ig
neous rock
is

not

recorded until it

reaches the Earth’s surface.

Constructed Response E.8.C.2 Score Rubric:




3 points

Response ad
dresses all parts of the question clearly and correctly.


A.

Diagram is completed correctly.


B.

Processes and locations identified: metamorphism below the earth’s surface
under conditions of extreme heat and pressure, along with weathering and
erosion at the e
arth’s surface. Metamorphism is the process in which rocks
undergo intense heat and pressure below the earth’s surface resulting in
metamorphic rock.


C.

Weathering and erosion breakdown rock which is then deposited as
sediments that undergo compaction and
cementation to form sedimentary
rocks.
