When plates move apart or diverge, it is called a normal fault (happens along a divergent boundary). When plates collide or converge, a reverse fault occurs (when the hanging wall pushes up, and the foot wall pushes down). When plates slide past each other, it is called a strike-slip fault, which typically occurs at a transform plate boundary.
Also, if you are still having doubts, do more research on strike-slip faults, normal faults, and reverse faults by just typing it in.

∙ 11y agoA reverse fault occurs when rocks are pushed together. If there is not line of weakness, there may not be a fault, and the strata may simply buckle to form a hogback, which will in time be eroded to form an anticline (where the rock strata have buckled upward). If more than one line of hogbacks were formed, there would be synclines between the anticlines.

What is crustal Compression?
when they are pushed together they form crustal rocks
When compression pushes rocks together it creates what type of fault?
A reverse or thrust fault.
What type of mountains form in where rocks are being pushed together?
Folded Mountain
Which way do rocks move in a fault?
A fault zone is created when directed stress (as opposed to isotropic stress that simply compacts materials) overcomes the physical strength of the rock to withstand pressure leading to a pervasive crack. If the stress that created the fault is pulling the rock apart, the block that lies above the fault (the hanging wall) is bound to sink and the rocks below the fault will move upwards relative to the hanging wall. This situation is termed a "normal fault" and occurs for example in rift zones all over the world. If confining pressure produces a fault, the hanging wall is pushed on top of the rocks below the fault. This is known as a "reverse fault" and is a common phenomenon in many mountain ranges. In a special type of stress regime, faults are created along which rocks are sliding past each other horizontally. They are called "transform faults".
Describe how compression forces make rocks move along a reverse fault?
A reverse fault occurs primarily across lithological units where as a thrust usually occurs within or at a low angle to lithological units.
Which type of fault occurs when rocks are pushed together as they meet?
These will form reverse or thrust faults.
Rocks being pushed together is what?
rocks being pushed together
What are fractures in rocks where movement occurrs?
A fault is a fracture in the rocks where movement occurs.
What type of mountain form in areas where rocks are being pushed together?
rocky moutains form when rocks are being pushed together.
What occurs when rocks above the fault surface move downward in relation to rocks below the fault surface?
This kind of fault is called a normal fault and is usually a sign of crustal extension.
What occurs when tension forces pull rocks apart?
Normal Fault
What is crustal Compression?
when they are pushed together they form crustal rocks
When compression pushes rocks together it creates what type of fault?
A reverse or thrust fault.
What type of mountains form in where rocks are being pushed together?
Folded Mountain
What occurs when opposing forces causes rocks to break and move horizontally?
The answer is Strike-Slip Fault.
Why are the alps where they are?
The two continents of Africa and Eurasia pushed together and folded the rocks into mountains.
When movement occurs along a strike-slip fault?
rocks move horizontally past one another
