The moho marks what type of boundary

http://www.columbia.edu/~vjd1/earth_int.htm WebThe lithosphere is the hard outer layer of the Earth, reaching approximately 100 kilometers deep (62 miles). The boundary between the crust and mantle of the lithosphere is known as the Mohorovic discontinuity, or simply Moho. Moho is located approximately 8 kilometers (5 miles) beneath the ocean and 32 kilometers (20 miles) beneath the continent.
