older arizona plates and its EZY 025
It is when the tectonic plates form and grow older.
The older denser plate subducts
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.

It is very difficult to answer this question. What determines the value of an older album is the condition it is in, whether it is by a group or artist that collectors care about, and whether it is rare or unique in some way. The best thing to do is go to a site like eBay and see how much collectors are asking for the older Jackson 5 albums.
Convergent boundary...it's on my homework
