1. Chapter 5 Deformation of the Crust
Mountain Formation

2. Individual mountains are parts of ________________________.
Adjacent mountain ranges make up a ________________________.
The largest mountain systems are part of two even larger systems called _________________….the circum-Pacific belt, and the Eurasian-Melanesian belt.

3. Plate Tectonics and Mountains
Both mountain belts are along __________________ plate boundaries…believed to be responsible for most mountain formation.
Some mountain ranges may have formed where now __________ plate boundaries may have collided in the past…______________________.

4. Continental—Oceanic Collisions
_______________ causes the continental crust to be pushed up to form mountains.
Melting rock creates ________ which rises to the surface, forming ______________.
Example…The ___________ mountain range in the Pacific Northwest.

5. Oceanic—Oceanic Collisions
Subduction causes melting of rock. Magma pushes up through the crust to form ________________ volcanoes.
A volcanic ______________ is the result. The Mariana Islands in the North Pacific Ocean are the ____________ of volcanic mountains that rose above sea level.

6. Continental—Continental Collisions
No subduction. When continental crust collides, it is _________________ to form high ____________ mountains.
The rock layers are squeezed together like an ______________.
Example…the ___________________.

7. Plateaus
Large areas of _________________ rock lifted high above sea level. Found next to folded mountains.
The rock layers are pushed upward _____________________ that they remain flat instead of deforming and folding into mountains.
