It is about 20 miles or 30 kilometers.
The two types of lithospheric crust are continental crust, which is thicker and less dense than oceanic crust, and oceanic crust, which is thinner and more dense than continental 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.
Continental crust is generally lighter than oceanic crust because it is thicker and less dense. Oceanic crust, being thinner and denser, tends to be heavier.
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
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.
It is not. The oceanic crust is thinner than the continental crust!
It is not. The oceanic crust is thinner than the continental crust!
younger
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.
denser (Apex)
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 :)
Oceanic crust is generally thinner than continental crust.
On average, it is much thicker than oceanic crust.
The two types of lithospheric crust are continental crust, which is thicker and less dense than oceanic crust, and oceanic crust, which is thinner and more dense than continental crust.
Oceanic crust is typically thinner than continental crust.
Oceanic crust is thinner and denser than 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
