1 This causes the magma in the mantle to spin slowly (convection).
How Mountains Form III. I. Earth’s core is hot. II. I. hot! II. This causes the magma in the mantle to spin slowly (convection). III. At Earth’s surface, tectonic plates, floating on the spinning magma, forms mountains 3 different ways: 1. 2. 3. Cause (fault?) Stress Result 3 Examples Folded mountains TEACHER NOTES below Materials per student: Student Handout Beforehand: Do yourself a huge favor and work through this exercise starting from a blank handout. It’ll help you explain it better to your students. It’s extra time, but it makes the lesson go much better! Procedure: (in a nutshell- have them copy/do everything shown on the ppt) First thing students do, as led by the ppt, is to title their paper. (removed for preview) (…Read notes on later slides for more info.) Other Teacher Notes: All text on this ppt is editable; change whatever you like.

2 Hanging wall- above the fault; it “leans into” the other
1. Folded Mountains Hanging wall Footwall (procedure continued) 3. Give students a couple of minutes to draw this in the “1. Folded Mountains” square I did a Google image search for “hanging wall and footwall” and inserted a real image of one on this slide. There are some gorgeous pictures to choose from. Hanging wall- above the fault; it “leans into” the other Footwall- below the fault

How Mountains Form III. I. Earth’s core is hot. II. I. hot! II. This causes the magma in the mantle to spin slowly (convection). III. At Earth’s surface, tectonic plates, floating on the spinning magma, forms mountains 3 different ways: 1. 2. 3. Cause (fault?) Stress Result 3 Examples Folded mountains Fault-block mountains Hanging wall Footwall Folded mountains occur along a reverse fault. 4. Go through the prompts listed for folded mountains. If students are working out a textbook, have them tell you these before revealing. 5. Then we move onto the second kind of mountain- Fault-block. Notice we used short sentences here. In this first column we’re modeling how to do this, so on the last 2 columns students will (hopefully) follow the same pattern. Compression squeezes the rock together. This causes rock in the hanging wall to go up, or “fold”. 3 examples are the Appalachians, Himalayas, and Alps

4 2. Fault-block Mountains
Foot wall Hanging wall 6. Students now draw this fault-block mountain.
