2. 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

3. 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)

4. 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

5. Folds

6. Monoclines

7. 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 ___________________

8. Faults The major types of faults are 1. 2. 3. 4.

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

10. 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

12. Joints ___________________along which ___________________ (detectable) ___________________has occurred

13. Joints

21. 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 _____________________________________ _

22. Mountain Types FoldedDomes and Basins Fault-block Volcanic

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

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

25. 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.

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