2 broadcategories that faults exist - faults the exhibit horizontal movement and also faultsthat exhibit vertical movement. Faults reflecting vertical motion includetensional (normal) and also compressional (reverse) faults. Tensional faults areproduced through stress (extension or pulling apart) the the crust bring about thehanging wall to move down relative to the footwall. A fault airplane is arelatively flat surface wherein rocks break because of displacement. The hanging wallis the block the rock that sits above the error plane; whereas, the footwall isthe block of rock that sits listed below the fault plane. Compressional faults areproduced through compression (shortening or advertise together) that the crustcausing the hanging wall surface to relocate up relative to the footwall. Note that in theanimation the rocks are layered. The larger rocks are uncovered at the bottom layersand end up being younger as you move up towards the surface. Research a allude alongthe error plane.
You are watching: Which statement describes the movement of crust in a normal fault?
The block that rocks that lie over the fault plane is the footwall:
a. True b. False
Which statement ideal describes the movement along normal faults?
a. The hanging wall surface moves downward relative to the footwall b. The hanging wall moves upward family member to the footwall c. The hanging wall surface moves horizontally family member to the footwall d. Faults are basic breaks in the crust along which no motion has emerged
a. The hanging wall surface moves downward family member to the footwall b. The hanging wall moves upward loved one to the footwall c. The hanging wall moves horizontally relative to the footwall d. Faults are an easy breaks in the crust along which no movement has developed
a. Compressional pressures b. Extensional pressures c. Lateral activity of the tardy d. Both compressional and also extensional pressures
Examine a suggest along the fault plane. The rocks in ~ a point over the fault plane of a normal fault would have:
a. Younger rocks overlying larger rocks b. Enlarge rocks overlying younger rocks c. Rocks on both political parties of the error the same age d. Both older and also younger rocks overlying each other independent that the type of error
a. Younger rocks overlying larger rocks b. Enlarge rocks overlying younger rocks c. Rocks ~ above both sides of the error the same age d. Both older and also younger rocks overlying each various other independent of the form of fault
a. Horizontal activity b. Vertical motion c. Very first vertical climate horizontal motion d. Very first horizontal motion followed by vertical activity
If girlfriend straddle both a normal and also reverse fault on the surface of the earth, the younger rocks are on the side that:
Both normal and also reverse faults are associated with vertical motions of rocks. Vertical movement along a turning back fault is caused through which force(s)?
a. Tensional pressures b. Compressional pressures c. Shearing or horizontal pressures d. Tensional and also compressional pressures
Normal faults are produced by tensional (extensional) forces.
a. True b. False
After movement along a error plane, weathering and erosion occurs faster on:
a. Upthrown block b. Downthrown block c. The very same on both the upthrown and also downthrown block d. Weathering and erosion go not take place
a. Where 2 plates come together b. Where 2 plates pull apart c. Where two plates on slide horizontally previous each other
a. Where two plates come together b. Where 2 plates traction apart c. Where 2 plates slide horizontally previous each various other
