Today you learned the three ways that Tectonic (Lithospheric) plates can interact.

A plate boundary is where two plates meet.

Three types of boundaries are:




The Aleutian Islands are an Island Arc that forms as two oceanic plates collide

Notice the chain ,or arc, of islands are all volcanic

Transform boundaries are the classic Earthquake boundary where plates are grinding past each other

Convergent boundaries occur when two plates collide or move together
