Question 1.
What is stress in geological terms?
Show hintHide hint
Think about how much force is acting on a surface.
Question 2.
Define strain in the context of geology.
Show hintHide hint
How does the material change shape?
3Question 3.
What does stress refer to in geological terms?
- Force per unit area
- Mass per volume
- Energy stored
Show hintHide hint
Think of how weight is applied to a surface.
4Question 4.
True or False: Strain always leads to rupture.
- True
- False
Show hintHide hint
Consider how rubber bands behave.
Question 5.
A rubber band stretches under increasing tension until it reaches its yield point and then breaks. Describe the stress and strain behavior throughout this process, and what implications does this have for understanding geological materials?
Show hintHide hint
Use the terms yield point and fracture point in your explanation.
Question 6.
If a fault accumulates stress over decades and reaches the yield point, what determines whether it will slip immediately following this point or may creep gradually?
Show hintHide hint
Consider the concepts of friction and fault mechanics.
