50 Miles
The crust is around five miles deep under the oceans and twenty five miles thick underneath the continents.
The thickness of Earth's crust under the continents varies, but on average it is around 30-50 kilometers (18-31 miles) thick. This thickness can increase to as much as 70 kilometers (43 miles) in certain areas such as mountain ranges.
Earth's crust is far thicker under the continents.
To the best of my knowledge, he was a Croatian geologist the developed the theory of discontinuity, which means that the crust of the Earth is about 6 miles thick under the oceans and about 22 miles thick under the continents. Now called 'Moho's Discontinuity' or simply 'Moho'

the earth's crust
The Earth's crust is thinnest under the oceans and thickest in the mountains.
The Earth's oceanic crust is very thin at the mid-ocean ridges, and gradually thickens as it moves away from the ridges. The continental crust is thickest under mountain ranges. The average depth of oceanic crust is around 5 miles. The average depth of continental crust is 22 miles.
Under the continents, the earth crust is on average around 50 kilometers thick, which is 50,000 meters or 5,000,000 centimeters. Under the oceans, the earth crust is on average around 7 kilometers thick, which is 7,000 meters or 700,000 centimeters.
The depth of the crust varies between 10 and 70 km in different areas, depending where you would measure it.
A pole shift is not what causes the continents to move. It is the pressures from under the oceans' plates.
The boundaries between continents are primarily defined by tectonic plate boundaries and oceanic features such as seas and oceans. These physical features create natural divisions that separate one continent from another.
