Mountain Building Day 2 September 30, 2010

OBJECTIVES 9/30 I will be able to… CLASSIFY THE DIFFERENT TYPES OF MOUNTAINS ___________________ I will be able to… GIVE ______________________________ OF DIFFERENT TYPES OF MOUNTAINS

Key Points Anticlines, synclines, monoclines, faults, and joints are land features created as a result of ___________________and ___________________ The set of processes that produce mountains is called ___________________ Mountains are classified by ______________________________________ The major types of mountains include: – ___________________ mountains (result of ______________________________________ ) – ___________________ mountains (result of ___________________ ) – ___________________ – ___________________ mountains (result of the build up of volcanic materials)

Folds During mountain building, rock layers are often bent into a series of “ripples” called _______________ Types 1.Anticlines: _________________________of rock layers 2.Synclines: __________________________in rock layers 3.Monoclines: ________________________________in otherwise horizontal sedimentary rock layers

Folds

Monoclines

Faults ________________are fractures in the crust along which _________________has taken place The surface above the fault is called the ___________________ The surface below the fault is called the ___________________

Faults The major types of faults are

Faults 1.Normal Faults -Occurs where the _________________________ ___________________ -Caused by ___________________ 2.Reverse Faults -Occurs where the _________________________ ___________________________________ ___ -Caused by ___________________

Faults 3. Thrust faults - Occurs where the ___________________________ _____________________________________ _ - Allow ___________________ of younger layers 4. Strike-slip faults - Occurs where the movement is mostly ___________________ and ___________________ to the trend of the fault surface

Joints ___________________along which ___________________ (detectable) ___________________has occurred

Joints

Mountains Why do all of these mountains look different Because different processes are responsible for their formation The collection of processes that produce mountains is called ___________________ Mountains are classified based on the _____________________________________ _

Mountain Types FoldedDomes and Basins Fault-block Volcanic

Folded Mountains Formed primarily by ___________________ Major force that causes formation is ___________________ Examples: _________________________________ _________________________________

Fault-Block Mountains Large-scale ___________________ ___________________ force ___________________ – Horsts are uplifted structures bordered on either side by sunken in valleys called grabens Examples: ______________________________________

Domes and Basins When ___________________produces a ___________________or elongated structure, the feature is called a ___________________. – ___________________are circular or elongated structures formed by uplifting of the underlying basement rock.

Volcanic Mountains Formed when one plate ___________________under another, ___________________, and ___________________rises to the surface Examples: _________________________________ _________________________________
