Answer:
"Tension stress of a fault" occurs when "slabs of rock" are being "pulled apart from each other".
Step-by-step explanation:
- When two equal forces that are acting in opposite directions are 'applied' on an object, the object is subjected to tension.
- Same is the case with the slabs of rocks that are being pulled apart from each other. Thus, the force that is applied on the rocks before a fault occurs is a tensional force.
- This force is quickly released after the fault has occurred.
