Chapter 5.3 Notes: Mountain Formation
1. Mountains
a. A mountain is a natural ______________ of the Earth’s ___________
rising abruptly to a ________________.
b. A mountain ____________ is a group of ______________ mountains
with the same general _____________ and ___________________.
i. For example: Mt. Everest is in the Himalaya mountain range
and Mt. St. Helens is in the Cascade mountain range.
c. A mountain ______________ is a group of ___________________
mountain ranges.
i. The Smoky, Blue Ridge, Cumberland, and Green mountain
ranges make up the Appalachian mountain system.
d. A mountain ___________ is a group of _________ mountain systems.
i. The two major mountain belts on Earth are the circum-Pacific
belt and the Eurasian-Melanesian belt.
2. Plate Tectonics and Mountains
a. _________________ believe that these two major mountain _______
are formed by __________________ plate boundaries and that most
mountain were formed by ___________________ lithospheric plates.
b. While some ________________ belts do not lie along ________ plate
boundaries, evidence suggest that these __________________ formed
where plates __________________ in the past.
c. Mountains can form at the three types of plate boundaries.
i. ___________________-___________________
1. In this _________________ the oceanic crust _________
under the continental crust forming ______________
mountains.
2. It is also believed that some of these mountains are
caused by ___________________ being scraped off.
3. _________________ mountains can also be formed at
this type of ________________________.
ii. ________________-_________________
1. In this collision the more ______________ oceanic plate
__________________ under the less dense oceanic plate
Name: ____________________________________ Date: __________________ Period: ______
and forms an ______ of volcanic mountains on the
_______________ floor.
iii. ___________________-_________________
1. The Himalaya Mountains were formed by two
_____________________ colliding. This can cause
severe _______________ in the area. These earthquakes
still occur today.
3. Types of Mountains
a. Mountains are ___________________ according to the way the crust
was _______________ and shaped.
b. Folded Mountains & Plateaus
i. _____________ mountains are landforms created when
________________ movements ____________ and uplift rock
layers. Basically, tectonic movements ________________ rock
layers together.
ii. ______________ is evident in the ____________ layers of
mountains formed this way.
iii. ____________________ are large areas of __________-topped
rocks high above _______ level and are formed by the same
force that forms folded mountains.
1. Plateaus are formed when __________, horizontal layers
of rock are ______________, generally next to a
mountain _____________.
2. The Tibetan and Colorado plateaus are next to the
Himalayan and Rocky mountains.
c. Fault-Block Mountains & Grabens
i. Fault-____________ mountains form where _______________
breaks the earth’s __________ into large blocks that become
_____________, causing some blocks to drop down relative to
other blocks.
1. An example of fault-block mountain is the Sierra Nevada
mountain range of California.
ii. _________________ are long, narrow _____________ formed
by faulting and downward _______________ of crustal blocks.
Name: ____________________________________ Date: __________________ Period: ______
1. Grabens are formed by the same ___________ that forms
fault-block ______________________.
2. An example of a graben is Death Valley in California.
d. Volcanic Mountains
i. __________________ mountains are formed when __________
rock erupts onto the Earth’s ______________ and can develop
on _______________ or ocean floor.
ii. Most volcanic mountains are formed on ______________ plate
boundaries and along ________-ocean ridges.
iii. ____________ ___________ are pockets of ______________
beneath the Earth’s _____________ that erupt onto the surface.
1. The ______________ islands were formed (are forming)
over hot spots, and are the ______ of volcanic mountains
that have breached the surface of the _______________.
2. The main island of Hawaii is about ______ tall with only
_______ above sea level.
e. Dome Mountains
i. A _____________ mountain is a landform created when
______________ rock pushes up ____________ layers on the
Earth’s surface and the layers then are worn away in ________,
leaving separate high ______________.
1. Examples include the ______________ Hills of South
Dakota and the ________________________ mountains
of New York State.
