Episode 7. Mountain Building
This program erodes the myth of the mountain as a solid, permanent structure. Animations are used to illustrate the process of orogeny (mountain building) through accretion and erosion, as well as the role of plate tectonics, the rock cycle, and how different types of rock are formed in the course of mountain building.
Are mountains permanent? Why not?
By what processes are mountins built?
What are cratons or shields?
What types of rock make up the Canadian Shield (as well as most other cratons)?
Describe the initial formation of earth's continental crustal materials.
How is greenstone believed to change into granitic continental rock?
Why are the youngest portions of the continents along the edges?
Who was James Hutton?
How does plate tectonics explain how ocean sediments are found in mountains?
What is orogeny?
Describe the rock cycle.
Describe the accretion process and how it relates to the building of the continents.
What is a terrain?
What commonly marks the boundaries of accreted terrains?
What is responsible for the continued uplift of many major mountain ranges?
What is isostasy?
What two factors contribute to the formation of mountains?
What does the Mediterranean Sea represent?
