Landforms, Mountains, Folding and Faults quiz
1. What kind of fault forms when the rock above the fault plane (the hanging wall) DROPS relative
to the rock below (the footwall)?
Reverse Fault
Normal Fault
Strike-Slip Fault
Thrust fault
None of the above
There are three major ways in which stress affects rigid rock during mountain building:
Compression (crustal shortening) ----><---Tension (crustal stretching) <---- ---->
Shear (forces parallel but in opposite directions)
---->
<---2. What does tensional stress usually cause?
Strike-Slip Faults
Reverse Faults
Normal Faults
Thrust Faults
Headaches
3. Compressional stress creates:
Thrust faults
Reverse faults
Folded mountains
All of the structures above
4. What is the name of the structure that forms when rock layers are uparched?
Anticline
Basin
Graben
Horst
Syncline
5. What caused the Appalachian Mountains to form?
Rifting along the Mid-Atlantic Ridge
A continent-continent collision between Africa and North America
Extensive hot spring activity
Volcanic activity during the Pre-Cambrian Era
6. The mountains of the Great Basin (Basin and Range) of California and Nevada are examples
of:
Fault block mountains
Volcanic mountains
Granitic batholiths
Folded mountains
7. The Alps, Urals, and Appalachian Mountains are examples of:
Fault block mountains
Volcanic mountains

Complex folded mountains
8. The San Andreas Fault in California is primarily a:
Dip-slip fault
Reverse fault
Strike-slip fault
Overthrust fault
9. Non-linear downfolded rock structures like those found in Michigan and Illinois are:
Anticlines
Basins
Grabens
Horsts
Synclines
10. Folding (of earth's crustal rocks) is usually the result of:
Tensional forces
Compressional forces
Shear forces
Faulting
11. Faults in which the movement is mainly horizontal, parallel to the fault, are called:
Strike-slip faults
Dip-slip faults
Normal faults
Reverse faults
12. Folded rock structures occur most often in:
Sedimentary rocks

Along transform fault plate boundaries
In the interior of continents
At convergent plate boundaries
