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.
Which statements best explain the formation of these mountains? Check all that apply.
Two parallel normal faults form. The hanging wall on the left slides down relative to the footwall. The hanging wall on the right slides down relative to the footwall.
Where does shearing often occur?
at a transform boundary
What type of stress occurs when one plate pushes against another?
compression
Which feature is most likely found at a divergent boundary?
fault-block mountain
Which type of fault occurs when rock is subjected to this type of stress?
normal
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.
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?
reverse
What type of stress occurs when a rock mass is pushed in opposite directions?
shearing
A scientist observes rock masses that have moved past each other in opposite horizontal directions. Which feature does the scientist observe?
strike-slip fault
A scientist has identified several features that formed due to compression. Which features might the scientist have identified? Check all that apply.
syncline anticline reverse fault
Which force created a fault-block mountain?
tension
Which type of stress causes fault-block mountains?
tension
