Lab 5: Weathering
GEOG 1113L – Introduction to Landforms Lab Name:
I. What is Weathering?
1. What does weathering create/provide and what would Earth’s surface be
composed of if weathering did not happen?
It creates the inorganic material in the soil, which vegetation needs to grow. The Earth's
surface have been composed of solid bedrock.
2. What is the difference between weathering and erosion?
Weathering preps the material to be ready to move and erosion is the actual movement
of the material.
3. Describe the process of frost wedging (frost action).
Water gets absorbed into the pores of a rock and then water freezes the rock expands
and the stress builds up causes the rock to break.
4. Similar to frost wedging, _salt crystal fractures rocks through crystal growth
growth
within the pores of the rock. These crystals originate from minerals dissolved in water
inside the rock that later evaporates and leaves behind _mineral grains_ .
5. The two previously mentioned types of weathering are both forms of
what? Granular disintegration
6. Which type of weathering causes metal to
rust? oxidation
7. Weathering that alters minerals in a rock via water, oxygen, carbon, and/or other organic
acids is called what?
Chemical weathering
8. Which type of weathering causes karst
topography? Carbonation
9. Name three features you might find in a karst
landscape. Sink holes, caves, dry valleys
10. What is one fact (from the video) about caves that you find
interesting? Caves have an ecosystem
11. Tree roots, lichen, and humans all play a part in weathering as well. Which type of
weathering is this called? Biological weathering
