Match each type of fault with its description and type of stress.

Question

1. normal fault
This fault can create features like scarps, horsts and grabens, and fault-block mountains.

compressional stress
2. reverse fault
tensional stress

This fault is where two rock blocks can grind past each other in a parallel direction.
3. strike-slip fault
shear stress

This fault occurs when a hanging wall block has risen relative to its footwall block.

Answer 1

Here are the matched descriptions and types of stress for each type of fault:

1. Normal fault

   • Description: This fault occurs when a hanging wall block has risen relative to its footwall block.
   • Type of stress: tensional stress
   • Note: This fault can create features like scarps, horsts, and grabens, and fault-block mountains.

2. Reverse fault

   • Description: This fault occurs when a hanging wall block has risen relative to its footwall block.
   • Type of stress: compressional stress

3. Strike-slip fault

   • Description: This fault is where two rock blocks can grind past each other in a parallel direction.
   • Type of stress: shear stress

So the correct matching is:

1. Normal fault: tensional stress
   Description: features like scarps, horsts, and grabens, and fault-block mountains.

2. Reverse fault: compressional stress
   Description: hanging wall rises relative to footwall.

3. Strike-slip fault: shear stress
   Description: two rock blocks grind past each other in parallel direction.
