The first plates were made of sheet iron, but tin became the standard by about 1920. The State of Arizona made its tags from sheet copper in 1932-1934. Porcelain plates were also quite common in the early days of vehicle plates, and Delaware was the last state to make porcelain plates in 1942.
Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.Two plates sliding past each other forms a transform plate boundary.Natural or human-made structures that cross a transform boundary are offsetâsplit into pieces and carried in opposite directions.hus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.
