Conclusion
Therefore from modeling the collision of two plates. We can conclude that when continental plates collide, new rock (mountains) are formed. When two oceanic plates collide the fastest plate sinks in the collison and when a continental plate and oceanic plate collide the oceanic plate goes under the continental plate.

In the experiment plates that separate we found out how mid ocean spreading of tectonic plates. We also found out how mid ocean ridges spreading relates to earthquakes and formation of new rocks.

Conclusion
The aim of the experiment was to investigate the movement of of convection currents. We found out that when the water temperatre was hot the pottassium moved around in a circlar motion while when the water temperature was cold the pottasium just sunk and fell to the bottom of the beaker. Thus the convection currents [...]
