To complete the chart, we need to match each type of fault with the correct force, motion, and plate boundary based on how earthquakes happen.
Here is the step-by-step breakdown for each row:
1. Strike-slip Fault
*
Type of Force: The blocks slide past each other horizontally. This is caused by
shearing force.
*
Motion: As seen in the diagram, the movement is side-to-side, so it is
horizontal.
*
Type of Plate Boundary: This happens where plates slide past one another, known as a
transform (or sliding) boundary.
2. Normal Fault
*
Type of Force: The hanging wall moves down because the crust is being pulled apart. This is caused by
tension force.
*
Motion: One block drops down relative to the other, so this is
vertical motion.
*
Type of Plate Boundary: This occurs where plates move away from each other, known as a
divergent boundary.
3. Reverse Fault
*
Type of Force: The hanging wall is pushed up because the crust is being squeezed together. This is caused by
compression force.
*
Motion: One block is pushed up over the other, so this is
vertical motion.
*
Type of Plate Boundary: This occurs where plates crash into each other, known as a
convergent boundary.

Final Answer:
| Type of Fault | Type of Force | Vertical or horizontal motion | Type of plate boundary |
| :--- | :--- | :--- | :--- |
|
Strike-slip | Shearing | Horizontal | Transform |
|
Normal | Tension | Vertical | Divergent |
|
Reverse | Compression | Vertical | Convergent |
