Journal 3 – Colliding plates

When doing this practical we were trying to relate it to how tectonic plates work. After the practical we found out that the paper and the tectonic plates work very similarly. Geologists believe that tectonic plates move from gravity. Since the plates are denser the under layer of the earth, they sink. The weight causes them to slide down and go by the lower subduction zones. When the plates push against each other it causes plate movements. The plates don’t move quickly, in fact they move as fast as your fingernails grows. The average is around two inches a year.
