This type of convergence often forms coastal mountain ranges and volcanoes. These two plates form the Andes mountains on th western coast of South America. The Third sub-type **=

Plate Tectonics are the theory of giant plates floating on top of the mantle like giant islands. The theory states that the reason mountains, volcanoes, trenches, and more are formed. They can also be the cause of great destruction such as earthquakes and tsunami. There are seventeen plates and micro-plate systems. How these plates form landmarks is a necessity to understanding our earth. The three major types of plate joining are Convergent, Divergent, and Transform boundaries. 

Convergent Boundaries  A convergent boundary is a plate boundary that collides with another plate. It is the main way that mountains are formed. This is how the Himalyas were formed. Thee India plate moves north and smashes into the Eurasian plate. This is the sub-type called continental-continental. Another type of sub-type is the continental-oceanic. This second type happens when an oceanic plate like the Nasco plate smashes into a continental plate like the South American plate. This type of convergence often forms coastal mountain ranges and volcanoes. These two plates form the Andes mountains on th western coast of South America. The Third sub-type
