How Mountains Form III. I. Earth’s core is hot. I. hot! II. This causes the magma in the mantle to spin slowly (convection). II. III. At Earth’s surface, tectonic plates, floating on the spinning magma, forms mountains 3 different ways: 1. Folded mountains 2. 3. Cause (fault?) Stress Result 3 Examples Copyright © InteractiveScienceTeacher.com 1. Folded Mountains Hanging wall Footwall Hanging wall- above the fault; it “leans into” the other Footwall- below the fault Copyright © InteractiveScienceTeacher.com How Mountains Form III. I.

At Earth’s surface, tectonic plates, floating on the spinning magma, forms mountains 3 different ways: 1. Folded mountains Footwall Cause (fault?) Stress Result 3 Examples 2. Fault-block mountains 3. Hanging wall Folded mountains occur along a reverse fault. 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 Copyright © InteractiveScienceTeacher.com 2.
