The boundary between the crust and the mantle is called the Mohorovicic discontinuity. It is also called simply the Moho and it is the abrupt divide between faster and slower speeds where the mantle starts.

∙ 8y agoThe boundary between the Earth's core and mantle is rather unimaginatively titled the Core-Mantle Boundary (CMB). The very base of the mantle (bottom 200 km) is sometimes considered a transition zone between core and mantle that is known as the D'' (D double prime) layer. The top of this layer is marked by a strong seismic discontinuity known as the Gutenberg discontinuity.
The upper boundary of the the mantle that separates the mantle from the crust is commonly referred to as the Moho (or to give it it's full title, the Mohorovičić discontinuity) named after the Croatian seismologist who discovered it.
