the theory that the Earth's lithosphere is divided into tectonic plates that move around on top of the athenosphere
|
plate tectonics
|
|
the boundary or place where two tectonic plates meet when they push into one another
|
convergent boundary
|
|
the boundary space between two tectonic plates when they move away from one another
|
divergent boundary
|
|
the boundary or space between two tectonic plates when they slide past each other horizontally
|
transform boundary
|
|
the amount of force that is put on a given material
|
stress
|
|
the kind of stress that occurs when an object is squeezed
|
compression
|
|
the kind of stress that occurs when an object is stretched
|
tension
|
|
when rock layers bend due to stress on the Earth's crust
|
folding
|
|
rock layers break due to stress and slide or move past each other on either side of the break
|
fault
|
|
when rocks are pulled apart due to tension the hanging wall moves down
|
normal fault
|
|
when rocks are pushed together by compression the hanging wall moves up
|
reverse fault
|
|
when opposing forces ( pulling and pushing) occur they cause the rock to break and move horizontally or slideleft to right
|
strike-slip faults
