Observe the two photos below. Then, use these photos showing the movement of Point B next to Point A on the fault block model to answer: Question A: After movement of Point B next to Point A, are rock layers X, Y, and Z still continuous when viewed from the side of the block model that Points A and B are on? Question B: Did movement of Point B next to Point A along the fault cause Point B to move up or down relative to Point D? Question C: Which block of rock is the hanging wall block and which block of rock is the footwall block – the side of the model with points A and D OR the side of the model with points B and C? Question D: What type of fault is formed by moving Point B next to Point A? Be specific. Question E: Is the type of fault formed by moving Point B next to Point A caused by tensional stress, compressional stress, or shear stress? Question F: Along which type of plate tectonic boundary would you expect to find the type of fault that formed by moving Point B next to Point A? Question G: Imagine that it has been thousands of years since the fault moved causing Point B to move next to Point A, describe what has likely happened to Rock Layer X on the left-hand side of the fault above Points A and D?

Question

Observe the two photos below. Then, use these photos showing the movement of Point B
next to Point A on the fault block model to answer:

Question A: After movement of Point B next to Point A, are rock layers X, Y, and Z still continuous when
viewed from the side of the block model that Points A and B are on?
Question B: Did movement of Point B next to Point A along the fault cause Point B to move up or down
relative to Point D?
Question C: Which block of rock is the hanging wall block and which block of rock is the footwall block – the
side of the model with points A and D OR the side of the model with points B and C?
Question D: What type of fault is formed by moving Point B next to Point A? Be specific.
Question E: Is the type of fault formed by moving Point B next to Point A caused by tensional stress,
compressional stress, or shear stress?
Question F: Along which type of plate tectonic boundary would you expect to find the type of fault that
formed by moving Point B next to Point A?
Question G: Imagine that it has been thousands of years since the fault moved causing Point B to move next
to Point A, describe what has likely happened to Rock Layer X on the left-hand side of the fault above Points
A and D?
