Lab # ____
Mountain Types
Name: __________________ Class: ____
Question: Will models help to explain how folded, block, and dome mountains are formed?
Materials: List all the materials used in the experiment
Hypothesis: Do this first by deciding the outcome of the experiment.
Observations: Write step by step directions that you used to create each mountain type. You can use
bullets or number each step. Complete 3 diagrams showing before, during, and after.
Analysis: Complete the following questions.
Folded:
a. What do the layers of the clay represent?
b. Where do the forces which cause the rocks to be deformed in this way originate?
c. Why are these mountains called folded?
Block:
a. What does each block of clay represent ?
b. What do the layers represent?
c. What line is simulated by the boundary between the 2 clay blocks?
Domed:
a. What does the marble represent in this experiment?
b. Why is the term domed used to name this type of mountain?
These boxes will have to be larger to allow room for your drawings. label your

Directions: Part # 1 Folds
1. You will need 2 colors of modeling clay.
2. Cut or flatten the clay into strips approximately 1 cm by 3 cm by 10cm.
3. Make 2 strips of each color.
4. Stack the strips, alternating the colors.
5. Place 1 narrow end against a wall. With your hand, apply pressure to the other narrow end.
Directions: Part # 2 Block
1. Separate the layers of clay
the original rectangles.
2. Re-stack the layers as before.
3. Cut the block lengthwise into 2
4. Holding the left portion of the
other block forward with the right

hand until the blocks slide apart, as in
Directions: Part # 3 Domed
1. Separate the layers of clay
carefully, and reshape each layer into
the original rectangles.
2. Re-stack the layers as before.
3.Place the clay on top of the marble and press to create pressure on the marble.
