one and a half miles thick
oceanic crust
No. Oceanic crust is about 5km to 10km thick. Continental crust is about 30km to 50km thick.
The thinnest layer of the Earth's crust is known as the oceanic crust. It is typically around 5-10 kilometers thick and is composed mainly of basaltic rock. The oceanic crust is denser and younger than the continental crust, which is why it is thinner.
continental: 25 to 70 km thick oceanic: 5km to 10km
The Earths crust is approximately 650 km deep.
Oceanic
The oceanic crust has an average depth in the range of 5-10 kilometers.
Continental crust is generally thicker than oceanic crust. Continental crust can be up to 70 km thick, while oceanic crust is usually around 5-10 km thick.
no
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
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.
Oceanic crust, new oceanic crust is produced by seafloor spreading.
