Earth Science Lesson 2 Forces in Earth's Crust
How is a plateau different from a fault-block mountain?
A plateau forms when a flat-block of rock is uplifted, and a fault-block mountain does not.
What type of stress occurs when one plate pushes against another? A) compression B) faulting C) shearing D) tension
Compression
Where does shearing often occur? A) along a normal fault B) along a reverse fault C) at a transform boundary D) at a divergent boundary
at a transform boundary
What stress causes a reverse fault to form? A) compression B) gravity C) tension D) shearing
compression
At which type of boundary does tension often occur? A) convergent B) divergent C) subduction E) transform
divergent
Which feature is most likely found at a divergent boundary? A) fold B) plateau C) fault-block mountain D) anticline or syncline
fault-block mountain
A scientist observes a feature where the hanging wall moved downward relative to the footwall. Which feature does the scientist observe? A) syncline B) anticline C) normal fault D) strike slip fault
normal fault
Which type of fault occurs when rock is subjected to a type of stress called tension? A) hanging B) normal C) reverse D) strike-slip
normal fault
A scientist discovers a rock that she determines to be a fault. She observes that the hanging wall of the fault is above the footwall. Which type of fault has she discovered? A) normal B) reverse C) strike-slip D) horizontal
reverse
A scientist observes a fault where the hanging wall has moved upward relative to the footwall. Which type of fault is the scientist observing? A) normal B) reverse C) strike-slip D) horizontal
reverse
What type of stress occurs when a rock mass is pushed in opposite directions? A)compression B) faulting C) shearing D) tension
shearing
A scientist observes rock masses that have moved past each other in opposite horizontal directions. Which features does the scientist observe? A) plateau B) syncline C) strike-slip fault D) fault-block mountain
strike-slip fault
According to scientists, which features might form due to compression? Check all that apply. A) syncline B) anticline C) normal fault D) reverse fault E) fault-block mountain
syncline, anticline, reverse fault
Which force created a fault block mountain? A) compression B) shearing C) subduction D) tension
tension
Which type of stress causes fault block mountains? A) compression B) shearing C) subduction D) tension
tension
The formation of fault-block mountains occurs when ______________.
the hanging wall on the right slides down relative to the footwall; the hanging wall on the left slides down relative to the footwall; and two parallel normal faults form
