FOLDS AND FAULTS I
1. What is a bend in layered rocks called?
- A fold
2. Folding in rock strata is the result of what kind of stress?
- Compressive stress
3. The following diagram shows a fold in which the rock layers are folded downward, with the limbs dipping down toward the axis of the fold. What is this type of fold called?
- A syncline
4. The following diagram shows a fold which has been pushed more strongly from one side so that the limbs dip in the same direction. What is this type of fold called?
- An overturned fold
5. What do we call a fracture in bedrock along which movement has taken place?
- A fault
6. What do we call a fault in which the movement is parallel to the dip of the fault surface?

7. What type of stress causes a normal fault?
- Tensional stress
8. The following diagram shows a fault in which the hanging wall block moves down along the dip relative to the footwall block. What is this type of fault called?
- A normal fault
9. What do we call a fault in which the movement is primarily horizontal, parallel to the strike of the fault, and the stress involved is shear stress?
- A stike-slip fault
