The change in environments that may have occurred at the end of the paleozoic era may have been caused by

The change of environment which might have occurred at the end of paleozoic era are caused by plate tectonics.

Tectonics plates is termed as scientific theory which describes large-scale motion where there is movement of seven large plates of larger number of small plates of lithosphere in earth.

The model of tectonic plates builds concept of continental drift. Lithosphere is the outermost shell which is found in planets and it is broken down into tectonic plates which are then composed of continental lithosphere and oceanic lithosphere.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
