Upper mantle

The upper mantle is a part of the Earth's mantle. The upper mantle begins below the Earth's crust and it ends at a depth of around 410 kilometres. The upper mantle is made up of two sections, the lithosphere and the asthenosphere.

Upper Mantle Media

• 

  1 = continental crust, 2 = oceanic crust, 3 = upper mantle, 4 = lower mantle, 5+6 = core, A = crust-mantle boundary (Mohorovičić discontinuity)

• 

  Cross-section of the Earth, showing the paths of earthquake waves. The paths curve because the different rock types found at different depths change the waves' speed. S waves do not travel through the core
