ESC1000 Chapter 10 - Mountain Building and Crustal formation
Type of mountains that typically form in large mountain ranges.
Upward fold in sedimentary rocks, with the oldest rocks in the middle.
Appalachians and Himalayas
Two examples of folded mountain ranges.
A roughly circular downward fold, like a rounded syncline, with the youngest rocks in the middle.
Basin and Range region, South East USA
Example of fault block mountains.
Black Hills, South Dakota
Example of a dome.
Three ways of making mountains: volcanic arcs, ductile deformation, _________.
Example of mountains formed by a volcanic arc.
A roughly circular upwarping (upward fold), like a rounded anticline, with the oldest rocks in the middle (other than the intrusion).
Mountain building process involving gradual compression and folding and warping.
fault block mountains
Landscape made by long series' of horst and grabens.
Mountains created by continental-continental collisions, which the largest and most complex type of mountains, and which typically form in large mountain ranges.
folding, pressure, time and warping
Four processes involved in forming mountains by ductile deformation (in alphabetical order).
The side of a fault that does not hang over.
The depressed block of land bordered by two parallel normal faults.
Great Lakes, Michigan Basin
Example of a basin.
The side of a fault that hangs over.
The elevated blocks of land that border two parallel normal faults.
horst and graben fault
Type of fault where a large block is bound by parallel normal faults on either side.
Example of mountains formed by a volcanic island arc.
A large mass of earth and/or rock rising above the common level of the adjacent land.
Tensional fault with the hanging wall block moving down relative to the footwall block.
Compressional fault, with the hanging wall block moving up relative to the footwall.
Type of fault where there is lateral movement rather than vertical movement.
Process involved in forming mountains by volcanic arcs.
Downward fold in sedimentary rocks with the youngest rocks in the middle.
Type of reverse fault, where the fault line is at a very low angle and the hanging wall slides over the footwall.
Three ways of making mountains: _________, brittle deformation, ductile formation.
Mountain building process where the pressure is applied too fast for the rocks to fold.
anticlines and synclines
Five landforms formed by ductile formation: basins and domes, _______ and ________, and folded mountains.
