________________________ is a force that acts on an area of rock to change its shape or volume. Because stress is a force, it adds ____________________ to the rock.
Three different kinds of stress can occur in the crust – _________________________________
___________________________________________________________________. Tension, compression, and shearing work over millions of years to change the _____________________
_______________________________ of rock.
The stress called ___________________________ __________________________on the crust,
_____________________ rock so that it becomes ____________________________________
_____________________________________________. Tension occurs where two plates are
_________________________________________________.
The stress force called ___________________________________ _______________________ rock until it ________________________ or ___________________________. Compression occurs where two plates are _______________________________.
Stress that ________________________ a mass of rock in two opposite directions is called
______________________. Shearing can cause rock to ________________________ and
____________________________ or to ____________________________________________.
A _______________ is a _________________ in the _________________ of the crust where rock surfaces _______________________________ each other. The rocks on ____________ sides of a fault can ______________ up or down or sideways.
Most faults occur along _______________________________, where the forces of plate motion
______________ or ___________________ the crust so much that the ____________________
____________________.
There are _______________ main types of faults: __________________ faults, _____________ faults and ________________________________________ faults.

_____________________ in Earth’s crust ______________ rock apart, causing _____________ faults. In a normal fault, the fault is at an ____________, so one block of rock _____________
___________________ the other block of rock. The block of rock that lies above is called the
________________ wall. The rock that lies below is called the _________________________.
When ________________________ occurs along a normal fault, the ______________________ wall slips ________________________. Normal faults occur where plates _________________ or pull apart.
A ______________________ fault has the same ____________________________ as a normal fault, but the blocks move in the _______________________ direction. In a reverse fault, the rock forming the hanging wall _______________________ and _______________ the footwall.
In a _______________________ fault, the rocks on either side of the fault _________________
__________________________________________ sideways, with ________________ up and down motion. A strike-slip fault that ______________________________________________ between two plates is called a ___________________________ boundary. The ____________
__________________________fault in California is an example of a strike-slip fault that is a sliding boundary.
Changing Earth’s Surface
Over millions of years, the ________________ of plate movement can __________________ a flat plain into ____________________________ such as anticlines and synclines, ___________ mountains, _____________________________________ mountains, and plateaus.
As tension forces pull the crust apart, two _______________________ normal faults can form a range of fault-block mountains.
