Oceanic crust is constantly created and recycled due to place tectonics.
Oceanic crust is created by spreading ridges in the ocean floor and the oceanic plates subside under continental plates thus forcing it back down into the magma as the plate grows.
Searching Oceanic Plate Tectonics on Google will provide images that made this easier to understand.

Which type of crust is heavier and younger?
Oceanic crust is both denser (and therefore heavier) and younger than continental crust.
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
What crust is older in years the continental or the oceanic?
Continental crust is far older than oceanic crust.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust.
Oceanic crust is than continental crust.?
younger

yes but oceanic crust is younger than continental crust because of deep sea trenches
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
Oceanic crust is what than continental crust?
Oceanic crust is thinner and denser than continental crust.
Is the continental crust thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
Why is oceanic crust lower than the continental crust?
Oceanic crust is thinner and of greater density than continental crust.
What is older the oceanic crust or the continental crust?
Continental crust is far older than oceanic crust.
Why is oceanic crust younger than the continental crust?
oceanic crust is constantly being subducted and replaced with new material at places like the mid Atlantic ridge.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is more dense than continental crust.
Which is denser Oceanic Crust or Continental Crust?
The Oceanic crust is denser than the continental crust
Is continental crust darker in color than oceanic or lighter?
Continental crust is generally lighter than oceanic crust.
