Mountain Building & Orogeny
This is the term for the process of mountain building caused by tectonic forces.
What is orogeny?
This type of fold arches upward with the oldest rocks exposed at the center.
What is an anticline?
This category of metamorphic rock has banding or layering due to directed pressure.
What is foliated metamorphic rock?
This park in Wyoming is famous for its major normal fault along the Teton Range.
What is Grand Teton National Park?
This province contains steep mountains, folded ridges, and valleys formed by Paleozoic compression.
What is the Ridge and Valley Province?
This early stage of mountain building occurs when new crustal fragments, or terranes, attach to a continent.
What is accretion?
This type of fault occurs when the hanging wall moves downward due to crustal tension.
What is a normal fault?
This low-grade metamorphic rock forms from shale and usually splits into flat sheets.
What is slate?
This park, known for extreme extension and below-sea-level basins, is part of the Basin and Range Province.
What is Death Valley National Park?
This Appalachian province includes the highest mountains in the eastern U.S., including the Smokies.
What is the Blue Ridge Province?
This major orogenic event shaped the modern Rocky Mountains.
What is the Laramide Orogeny?
This type of fault is associated with convergent boundaries and places older rocks over younger rocks.
What is a thrust fault?
This non-foliated metamorphic rock forms from limestone.
What is marble?
This Appalachian park contains high-grade metamorphic rocks and large thrust sheets.
What is Great Smoky Mountains National Park?
The Basin and Range Province is actively stretched by this type of tectonic stress.
What is tensional stress?
These ancient mountains formed through several orogenies including the Taconic, Acadian, and Alleghenian.
What are the Appalachian Mountains?
This fold type forms a bowl-shaped depression with the youngest rocks in the center.
What is a syncline basin?
This metamorphic rock represents high-grade metamorphism and displays alternating light and dark mineral bands.
What is gneiss?
This Appalachian park features folded and faulted sedimentary rocks in the Ridge and Valley Province.
What is Shenandoah National Park?
Continents grow at convergent margins when small crustal fragments attach to the continent in this process.
What is terrane accretion?
Compared to the Rockies, these mountains are older, more eroded, and contain more metamorphic rock.
What are the Appalachians?
These faults dominate the Basin and Range Province and create alternating mountains (horsts) and valleys (grabens).
What are normal faults?
This metamorphic progression goes from lowest to highest grade: slate -> phyllite -> schist -> ________.
What is gneiss?
Compared to the parks in Module 5 (volcanoes), this Module 6 park formed through collision rather than volcanism.
What is Shenandoah or Great Smoky Mountains National Park?
This province west of the Appalachians consists of relatively flat, uplifted sedimentary rocks.
What is the Appalachian Plateau?
