a collision is a kind of convergence & the collision of tectonic plates changes the order of the rock layers by compressing rock layers into faults and folds ->  the convergence of tectonic plates changes the order of rock layers by compressing rock layers into faults and folds  if an event changes something then that event causes that change & the convergence of tectonic plates is a kind of event ->  if the convergence of tectonic plants changes something then it causes that change  the convergence of tectonic plates changes the order of rock layers by compressing rock layers into faults and folds & if the convergence of tectonic plants changes something then it causes that change ->  the convergence of tectonic plates causes the order of rock layers to change by compressing rock layers into faults and folds  sedimentary rock is a kind of rock & sedimentary rocks are formed in layers ->  sedimentary rock is a kind of rock with layers  the convergence of tectonic plates causes the order of rock layers to change by compressing rock layers into faults and folds & sedimentary rock is a kind of rock with layers ->  the convergence of tectonic plates causes the order of layers in sedimentary rock to change by compressing the layers into faults and folds  the convergence of tectonic plates causes the order of layers in sedimentary rock to change by compressing the layers into faults and folds & a fold is observed in layers of sedimentary rock ->  the fold observed in layers of sedimentary rock is caused by the covergence of tectonic plates  the fold observed in layers of sedimentary rock is caused by the covergence of tectonic plates & a crustal plate means a tectonic plate ->  the fold observed in layers of sedimentary rock is caused by the covergence of crustal plates  the fold observed in layers of sedimentary rock is caused by the covergence of crustal plates & if something is caused by something else then that something resulted from that something else -> the fold observed in layers of sedimentary rock resulted from the covergence of crustal plates
