Answer to Question 1

Answer: Brittle faults and joints form in rocks close to the surface whereas plastic flow occurs at deeper levels where high pressure inhibits fracturing and temperature lowers rock strength. Tension elongates and thins crust by movement on normal faults in shallow rocks and taffy-like stretching of plastic rocks at deeper levels. Compression shortens and thickens crust by producing folds, reverse faults, and thrust faults in shallow rock, and plastic flow in deeper rock. Folds form by plastic flow deep in the crust but also develop at and near the surface in sedimentary rocks where bending of thin layers and slippage along layers take place.

Answer to Question 2

Answer: C
