The boundary between the brittle part of the upper mantle and the crust (both oceanic and continental) is known as the Mohorovičić Discontinuity (Moho) according to Geology.com.

At constructive plate boundaries, mid-ocean ridges will be formed. ... This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate.

As magma cools into rock, magnetite grains, dispersed within and aligned with the magnetic field, become fixed: This records Earth’s polarity at the time the rock formed. Oceanic crust, made of ...
