  1. The Mohorovicic Discontinuity (or Moho) is the boundary between the Earth's lower crust and upper mantle. It is named after a Croatian seismologist of the same name. It is 5 km thick at the mid-ocean ridges and 75 km thick at the continental shelf.

    The Moho serves to separate both oceanic crust and continental crust from underlying mantle. The Moho mostly lies entirely within the lithosphere; only beneath mid-ocean ridges does the Moho also define the lithosphere-asthenosphere boundary. The Mohorovičić discontinuity was first identified in 1909 by Andrija Mohorovičić, a Croatian seismologist, when he observed the abrupt increase in the velocity of earthquake waves (specifically P-waves) at this point. Ophiolites are sections of oceanic crust and possible mantle rock that have been obducted into the continental crust during plate collisions.

    Just to let you know its spelled Mohorovicic not Mohovoric


  2. It is the area between the crust and the mantle. It is when the materials are turning from solids (like in the crust) to a liquid-like form (like the mantle).
