Let’s have a look at...
Activity 1 (6 points)
Recall the description of physical and chemical changes. Determine if the weathering
process enumerated below is mechanical (physical)or chemical. *One item is done for you.
Types
Frost
wedging
Description
The water enters the cracks of rocks. The water will freeze
*Mechanical
during the wintertime and expands the rock at the same time.
When the ice thaws, water can flow further into the crack. As
the process repeats, the rock weakens and breaks into smaller
fragments.
Insolation
Rocks degrade into smaller pieces because of expansion and
contraction caused by temperature changes.
Unloading
When overlying rocks are eroded, the rock below expands
upward. This expansion may separate the other rock from the
rock body.
Oxidation
Oxygen dissolved in water will oxidize some minerals in rocks.
Hydrolysis
Water will react with minerals in rocks.
Carbonation Carbon dioxide dissolved in water reacts with carbonate
and Solution minerals in rocks (answer for item 6).
Biological
Action
Some plants and animals may create chemical weathering by
releasing chelating and unifying compounds that react with
some minerals in the rocks.

Activity 2 (5 pts. Clear association of volcanism and plate tectonics).
Explain how volcanic activities are related to plate tectonics in not more than 7
sentences. Write your answer below. Remember to cite your sources.
REFLECTION
Do humans affect or influence both exogenic and endogenic processes? If we do, how? If we
do not, why not? Share your thoughts below. Do not forget to apply what you learned in this
topic.
