We've simulated in the classroom how mountains can be made. Some mountains are made by compressed folding crust, some are made by blocks that are stretched out, squeezed, or uplifted. Tomorrow: we'll finish that, do a brief discussion of dome mountains, and then move into volcanoes. Anyone interested in challenge or EC work: you have 1 week to make a working volcano model. Limits: no flammable or explosive chemicals can be used in the classroom to make the volcano "erupt".
Homework: some classes were to answer questions in writing:
Blue: 1. Can you explain how mountains fold?
2. Compare and contrast "anticline" and "syncline".
3. Explain the difference between when crust folds , and when it breaks. Why does this
happen? What does it cause?
Yellow: 1. How is a normal fault different from a thrust fault?
2. How is a normal fault different from a reverse fault? and
3. How are normal, thrust & reverse faults different from a strike-slip fault?
