Oceanic and Contintental crust are different in composition as well as size and density

Continental- granitic/50-100km thick

Oceanic- basaltic/ up to 10km thick

Oceanic crust is more dense making it subduct under continental crust

How are oceanic crust and continental crust different?

Additionally, oceanic crust is constantly being created and destroyed through seafloor spreading and subduction processes, whereas continental crust is relatively stable.

How is the oceanic crust recycled?

Convection in the mantle helps to recycle the oceaniccrust, not all of Earth's crust. There are two different parts to the crust. Oceanic and Continental. The Oceanic gets recycled, so when Scientists measure the age of the rocks, they're young.
