Exploration Phase
- Have students develop a model of a thrust fault. Instructions to students:
- Locate points C and D on your model. Move Point C next to point D. Observe the cross-section of your model.
- Have students draw the thrust fault as represented by the model they have just constructed.
Concept Development
- Ask the following questions:
- Which way did point D move relative to point C?
- What happened to rock layers X, Y and Z?
- Are the rock layers still continuous?
- What likely happened to the river? the road? the railroad tracks?
- Is this type of fault caused by tension, compression or shearing?
- Explain that this type of fault is known as a thrust fault.
- Have students label their drawing "thrust fault".
- An example of a thrust fault is the fault in which the Northridge earthquake occurred. The thrusting movement raised the mountatins in the area by as much as 70 cm.
