Let’s review the fault types and descriptions again for accuracy:
1. **Rock layers are placed under compressional stress:**
**Answer:** **reverse fault** (In a reverse fault, the hanging wall moves up relative to the footwall due to compressional stress.)
2. **Rock layers are placed under tensional stress:**
**Answer:** **normal fault** (In a normal fault, the hanging wall moves down relative to the footwall due to tensional stress.)
3. **Rock layers are placed under shear stress:**
**Answer:** **strike-slip fault** (In a strike-slip fault, the movement of the rock occurs horizontally, parallel to the fault line, typically due to shear stress.)
4. **Hanging wall has dropped relative to footwall:**
**Answer:** **normal fault** (This is characteristic of a normal fault where the hanging wall moves down.)
5. **Hanging wall has risen relative to footwall:**
**Answer:** **reverse fault** (This occurs in a reverse fault where the hanging wall moves up.)
6. **Occurs when tectonic forces cause rock layers to break apart and move in opposite, parallel directions:**
**Answer:** **strike-slip fault** (This type of fault involves lateral movement of rocks past one another.)
7. **Occurs at convergent boundaries where two tectonic plates collide:**
**Answer:** **reverse fault** (Reverse faults are typically associated with convergent boundaries because they involve compression.)
8. **Occurs at divergent boundaries where two tectonic plates separate:**
**Answer:** **normal fault** (Normal faults are associated with divergent boundaries because they involve extension.)
So, to confirm the answers:
- **normal fault**: placed under tensional stress, hanging wall drops, occurs at divergent boundaries
- **reverse fault**: placed under compressional stress, hanging wall rises, occurs at convergent boundaries
- **strike-slip fault**: placed under shear stress, movement in opposite parallel directions
These are indeed the correct matches based on the definitions of the fault types. Thank you for your patience!
