Ch 12: Rock Deformation and Mountain Building

About This Chapter

Watch video lessons on rock deformation and mountain building and learn about different kinds of folds and faults. These lessons are part of our earth science learning materials.

Rock Deformation and Mountain Building - Chapter Summary and Learning Objectives

Rocks are constantly bent, twisted and fractured by various stresses within the earth, causing these rocks to change in shape or size. Through this chapter, you can learn about the stages of rock deformation as well as processes - including folding, faulting and metamorphism - that lead to the formation of mountains. By the end of this series of video lessons, you should be able to do the following:

  • Identify the three types of differential stress that cause rock deformation.
  • Differentiate among types of folds, including anticlines, synclines, domes and basins.
  • Discuss the difference between tensional, compressional and shear faults.
  • Define various terminology associated with mountain building, including volcanic arc, continental collision and isostasy.
