Here are the answers based on the provided images depicting fault lines and their effects on rock layers and surface features: 1. If point B moves relative to point A, what type of fault is shown? This shows a normal fault. Point B moving down relative to Point A indicates the hanging wall (the block above the fault plane) moving down relative to the footwall (the block below). This is characteristic of normal faults, which are caused by tensional forces (pulling apart). 2. Explain what happens to the rock layers X, Y, and Z? In a normal fault, the rock layers are pulled apart. Layers X, Y, and Z are stretched and thinned. The fault plane creates a displacement, with the layers on one side of the fault shifted vertically relative to the other side. 3. What happens to the rivers, road, and railroad tracks? The rivers, road, and railroad tracks are offset (displaced) due to the fault movement. They are broken and shifted vertically, reflecting the movement of the Earth's crust. 4. What force is caused by this type of fault? Tensional forces (pulling apart) cause normal faults. 5. If point D moves relative to point C, what type of fault is shown? This shows a reverse fault. Point D moving up relative to Point C indicates the hanging wall moving up relative to the footwall. This is characteristic of reverse faults, which are caused by compressional forces (pushing together). 6. Explain what happens to the rock layers X, Y, and Z? In a reverse fault, the rock layers are compressed and pushed together. Layers X, Y, and Z are shortened and thickened. The fault plane creates a displacement, with the layers on one side of the fault shifted vertically relative to the other side. The hanging wall overrides the footwall. 7. What happens to the rivers, road, and railroad tracks? Similar to the normal fault, the rivers, road, and railroad tracks are offset (displaced) due to the fault movement. However, in this case, the displacement is often more abrupt and the features are pushed upwards or compressed. 8. What force is caused by this type of fault? Compressional forces (pushing together) cause reverse faults. 9. If you were standing at point F and looking across the faults, which way did the block on the opposite side move? Standing at point F and looking across the fault, the block on the opposite side moved downward (this refers to the normal fault scenario in the second image).10. Explain what happens to the rock layers X, Y, and Z? (Referring to the fault at point F) The rock layers are stretched and thinned due to the tensional forces causing the normal fault. The layers are displaced vertically, with the block opposite point F dropping down. 11. What happens to the rivers, road, and railroad tracks? (Referring to the fault at point F) The rivers, road, and railroad tracks are offset vertically, mirroring the downward movement of the block on the opposite side of the fault from point F. 12. What force is caused by this type of fault? (Referring to the fault at point F) Tensional forces (pulling apart) caused this normal fault. Remember! that these interpretations are based on the simplified diagrams. Real-world fault systems are often much more complex.
