Co to jest Transform Boundary?

A transform boundary is a type of plate boundary where two tectonic plates slide horizontaly patt each texr. Unlike divergent boundaries, where plates move aparte and create new cruct, or convergent boundaries, where plates collide and subduct, transformm boundaries involve lail slip. The relativa motion is dominujący strikee-slip, meaning the moverevenment is parallel to the fault strike.
