2. Rock Stress Compression: BOP IT Tension: PULL IT
Squeezes and shortens a body of rock
Near convergent plate boundaries
Tension: PULL IT
Stretches and pulls a body of rock apart
Near divergent plate boundaries
Shear Stress: TWIST IT
Pushes parts of the body of rock in opposite directions
At transform plate boundaries

3. Rock Stress

4. Faults: A break in a body of rock along which one block slides relative to another
Normal Faults: form at divergent boundaries, where the crust is pulling apart
Reverse Faults: form a convergent boundaries, where the crust is pushed together or compressed
Strike-Slip Faults: form at transform boundaries, where tectonic plates grind past each other as they move in opposite directions

5. Mountain Ranges and Systems
Mountain Ranges: a series of mountains that are closely related in orientation, age, shape, and structure
Mount Everest is part of the Great Himalaya Range
Mountain Systems: a group of mountain ranges that are next to each other
The Appalachian mountain system is made up of several mountain ranges

6. Plate Tectonics and Mountains: Mountains are formed mainly by the collision of 2 plates.
When oceanic crust meets continental crust the continental crust is pushed.
The oceanic crust sinks underneath and melts forming volcanoes.
When two oceanic plates collide, the more dense one sinks below the other.
As it sinks, it melts to form volcanoes.
When two continents collide, the crust is pushed upwards.
The Himalayas were formed this way when India ran into Asia. (still growing)

7. Types of Mountains Folded Mountains
Highest mountain ranges in the world
Tectonic plates colliding squeeze rock layers upward, folding and faulting them
Himalayas, Appalachians, Alps are examples
Plate Tectonics Comic Book Page 13

8. Types of Mountains Fault-Block Mountains
Crust has been stretched and broken into large blocks
Happens where plates are being pulled apart
Sierras, Wasatch, and Teton’s are examples
Plate Tectonics Comic Book Page 13

9. Types of Mountains Domed Mountains
Rare type formed when magma rises and pushes up against the surface without breaking through
A rounded mountain with a center peak
Henry Mts. In Utah, Black Hills of S.D. are examples

10. Types of Mountains Salt Domed Mountain
Astronaut view of domed mountain created when salt, underlain with petroleum deposits was squeezed up through more dense rock layers towards the surface.
