Yes, the Earth's continental crust is generally older than the oceanic crust. Continental crust can be billions of years old, while oceanic crust is continuously being created and is typically less than 200 million years old.
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
It is not. The oceanic crust is thinner than the continental crust!
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
Continental Crust.
There are two types of crust, and they are the oceanic crust and the continental crust. Oceanic crust is thinner yet more dense than continental crust, and continental crust is on average older than oceanic crust :)
The lithosphere can have two main types of crust: continental crust and oceanic crust. Continental crust is thicker, older, and less dense than oceanic crust. Oceanic crust is thinner, younger, and denser, primarily composed of basaltic rocks.
The continental crust is thicker and less dense than oceanic crust. Oceanic crust is younger and primarily composed of basalt, while continental crust is older and made up of a variety of rock types, including granite and sedimentary rocks.
Continental crust is thicker, less dense, and typically older than oceanic crust. Oceanic crust is thinner, more dense, and younger as it is constantly being formed at mid-ocean ridges and being recycled at subduction zones.
