This is not true. There is quite some oceanic crust that is older than the Cretaceous still present and we even find small parts of very ancient oceanic crust on the continents as ophiolites.
On average the oceanic crust might be of Cretaceous or even younger age because it is constantly recycled into the mantle in subduction zones and created on mid ocean ridges.
What else can I help you with?
Oceanic crust is than continental crust.?
younger
Is ocean crust or landform crust yonger?
Ocean crust is younger than landform crust. Oceanic crust is constantly being created at mid-ocean ridges through volcanic activity, making it much younger in comparison to the older landform crust found on continents.
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
Oceanic crust near the mid ocean ridge is younger than oceanic crust farther away from the ridge?
hit the books!!
Is oceanic crust near the mid ocean ridge younger than oceanic crust farther from the ridge?
haha i really dont know
Which type of crust is heavier and younger?
Oceanic crust is heavier and younger compared to continental crust. It is denser because it is composed of basaltic rocks, while continental crust is made up of less dense granitic rocks. Additionally, oceanic crust is continually being formed at mid-ocean ridges through seafloor spreading, making it much younger on average than continental 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.
Oceanic crust is what than continental crust?
Oceanic crust is denser and thinner than continental crust. It is mainly composed of basalt, while continental crust is primarily made up of granite. Oceanic crust is also younger and constantly being formed at mid-ocean ridges through volcanic activity.
What types of crust can be found in the lithosphere?
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.
Is oceanic crust near the mid ocean ridge younger than oceanic crust farther away from the ridge?
haha i really dont know
What is the difference between continential and oceanic crust?
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.
