• Welcome to the Weathering Quiz!
• You will write out all of your answers on a sheet of
paper. There are 13 questions on this part of the
quiz. Read each question carefully and answer each
question to the best of your ability.
• After completing this part of the quiz you should
answer questions 14 and 15 by clicking on the link

An animal burrow is centered in the photo. Animals that
burrow into the ground are a source of weathering.
1. Is this a type of chemical or mechanical weathering?
Here you see a picture from
the school’s parking lot. You
will notice many cracks in the
asphalt.
2. What process could
happen this winter to enlarge
these cracks?
A. Abrasion
B. Acid rain
C. Ice wedging
D. oxidation
Here we see a close up photo of many small holes or pockets that
have formed on this rock.
3. Describe why this rock is an example of differential weathering.
4. The holes are forming as water dissolves the rock in these
locations. Would this weathering be mechanical or chemical?
• The rocks in this photo were found in a small creek/stream
bed.
5. What type of mechanical weathering is making these rocks
so smooth?
A. Abrasion
B. Ice wedging
C. Acid rain
D. Plant actions
6. Describe how this type of weathering works?
7. How does moss weather rocks?
A. The roots of the moss gradually break the rock apart.
B. The moss is home to a type of insect that can break the
rock down.
C. The moss produces a weak acid that slowly eats away at
the rock.
D. The moss attracts worms and other invertebrates that
break the rock down.
8. Is this chemical or
mechanical?
Here we see a large rock being taken over by an even larger
tree.
9.Describe how this rock can be weathered as the tree
continues to grow over it?
10. The large rocks pictured below have a large crack
running between them. How did weathering most likely
cause this rock to crack?
A. abrasion
B. acid rain
C. animal actions
D. ice wedging
The pole that holds the ‘No Dumping’ sign is being rapidly
weathered by a form of chemical weathering.
11. What is the scientific name for this type of weathering?
• 12. Which of the following agents of
weathering influences weathering the most?
• A. animals
• B. plants
• C. oxidation
• D. water
• 13. Below is a photo of the Rocky Mountains.
A large amount of weathering happens in
these mountains. Describe three factors that
allow weathering to happen more rapidly in
the rocky mountains compared to an area that
does not have such a high elevation
