Final Answer:
Normal: Dip-slip movement; diagram shows blocks moving vertically along a fault plane; found in divergent or convergent boundaries.
Reverse: Dip-slip movement (compressional); diagram shows wall pushed up over footwall; found in convergent boundaries.
Strike-slip: Horizontal movement; diagram shows blocks sliding past each other laterally; found at transform boundaries.

Explanation:
Let’s fill the table step by step:
1.
Normal fault:
- *Type of Movement*: Dip-slip — meaning one block moves *up or down* relative the other, dip (slope) of the fault. In a normal fault, the hanging wall (upper block) moves *down* relative to the footwall (lower block).
- *Where it’s found*: Usually where Earth’s crust is being pulled apart — like at divergent plate boundaries (e.g., mid-ocean ridges) or rift zones (like the East African Rift).
2.
Reverse fault:
- *Type of Movement*: Also dip-slip, but now the hanging wall moves *up* over the footwall because the rocks are being squeezed together.
- *Where it’s found*: In areas where plates push together — convergent boundaries (e.g., Himalayas formed by reverse faults and folding).
3.
Strike-slip fault:
- *Type of Movement*: Horizontal — blocks slide *sideways* past each other. No up/down motion — just left or right.
- *Where it’s found*: At transform boundaries, where plates slide past each other (e.g., San Andreas Fault in California).
For diagrams (you’d draw them):
- Normal: Two blocks with a slanted line (fault), top block dropped down.
- Reverse Same slanted line, but top block pushed up.
- Strike-slip: Vertical fault line, arrows showing left/right motion on each side.
That’s how you complete the table!
