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 PlateausLarge 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.
