1. Rocks vary in color, size, texture and shape. They are classified based
on how they were formed. Which of the following deals with the study of
rocks?

A. Biology B. Geology
C. Paleontology D. Petrology

D

2. Halite is made when a body of seawater becomes closed off and evaporates
and salt precipitates out and is deposited as crystallized halite. What type of
sedimentary rock is formed?

A. Clastic B. Chemical C. Organic D. Pyroclastic

B

3. Igneous rock is divided into two groups, extrusive and intrusive Extrusive igneous
rocks form when magma makes its way to its surface as lava and the cools
forming rocks. Which will be the characteristics of the crystals?
A. Crystals are very large.
B. Crystals are phaneritic.
C. Crystals are fine grained.
D. Crystals are coarse grained.

4. Regional metamorphism occurs due to changes in pressure and temperature
over a large region of the crust. It may happen when rock is
buried deep below the surface or where pieces of the Earth’s crust collide.
Which is a metamorphic rock?
A. Breccia B. Conglomerate C. Marble D. Sandstone

C

5

Igneous and metamorphic rock can be buried and undergo tremendous
heating and stress. What is the process of transformation of one rock type
into another?
A. Compaction B. Lithification C. Metamorphism D. weathering

C

6

What type of rocks are formed from sediments over long period of time?
A. Igneous Rocks C. Metamorphic Rocks
B. Sedimentary Rocks D. Minerals

B

7. Which type of rock is formed when heated and compressed over time?
A. Igneous C. Sedimentary
B. Metamorphic D. All are correct

B

8. What is the natural process that causes one kind of rock to change into another
kind?
A. weathering B. rock cycle C. Sediments D. Metamorphism

B

Which of the following represents the correct order of the processes
responsible for the formation of sedimentary rocks?
A. Compaction, cementation, deposition, weathering, erosion

12. A student obtained a cup of quartz sand from a beach. A saltwater solution is
poured into the sand and is allowed to evaporate. Afterwards, the mineral residue
from salt water solution cemented the sand grains together. Which of the following
is most likely formed?
A. extrusive igneous rock
B. intrusive igneous rock
C. metamorphic rock
D. sedimentary rock

C

13. Which of the following is true about rocks?
A. Coal is not considered a rock.
B. Rocks do not contain minerals.
C. Most rocks are a mixture of minerals.
D.Rocks are composed of only one mineral.

14. What is the type of rock formed from lava that cools quickly that results to
finer grain and smaller size of crystals?

B Intrusive igneous rock
C. Metamorphic rock
D. Sedimentary rock
