The mean thickness of oceanic crust is 5 km whereas that of the continental is around 30 km. The continental crust is thicker in the areas of major mountain systems. It is as much as 70 km thick in the Himalayan region.
The first transition is probably related to temperature-dependent ductility of the crust at shallow depths (7 8 km on Europa). The second transition is attributed to the influence of subsurface oceans on all three satellites, which constrains Europa's icy shell to be at least 19 km thick. ...

The surface of the earth can be divided into the continental crust and the oceanic crust. The continental crust is made mostly of granite while the oceanic crust is made of basalt. The average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is ...
1.12.4.1 General Seismic Structure of the Oceanic Crust Low velocities (<5 km s−1 P-wave velocity), high seismic attenuation, and a strong velocity gradient at its lower boundary which can be imaged with seismic reflection techniques, characterize the upper few hundred meters of the oceanic ...
The results show a clear age-latitude dependence where sediment thickness increases with age of the oceanic crust, toward high southern and northern latitudes and toward the equator. In addition, we calculate the total volume of sediments in the oceans, which shows an increase of 29.7%, compared...

Present day thickness of the continental crust is relatively well known at regional and global scales and ranges from just a few kilometers thicker than oceanic crust (~6–10 km) to over 80 km at some convergent margins, such as in Himalaya-Tibet1. In consideration of continental crust...
