A
The Rocky Mountains of western North America were produced in an orogeny called the ________.
Lamaide orogeny
What is the major difference between a subduction zone and a collisional mountain chain?
a subduction zone has active volcanism
Most active faults pose a risk to society because they can potentially produce ________.
earthquakes
The Sierra Nevada Mountains of California, and the Teton Mountains of Wyoming, ranges are examples of ______
fault blocks uplifted by plate teriarity to quaternary normal faulting
Orogenesis refers to the formation of ________.
mountains
The Appalachian Mountains may have once been as lofty as the Himalayan-Tibetan Mountain belt is today. Why are they not this high now?
They formed long ago and erosion has delved them to their present low elevation
Mountain building uplifts rocks against the force of gravity raising their potential energy, which requires work by the earth system. Based on the relative motion of fault blocks, what type of fault would you expect to require more energy than the others?
Thrust
The Appellations were formed by three phases of _______ organy
collisional
Subduction occurs when ______ rocks are forced beneath ____ rocks
oceanic or continental oceanic
What is a modern theory for orogenesis (mountain building)
plate tectonics theory
