What are the characteristics of oceanic crust?

Oceanic crust is thinner and more dense than continental crust. This is because it has been compressed by the weight of the oceans it carries above it. It is also much younger than Continental crust, as it is usually less than 200 million years old. Oceanic crust is formed at constructive (divergent) plate boundaries and is destroyed by subduction at destructive (convergent) plate boundaries.
