Questions & Step-by-Step Solutions

What is the approximate temperature at the boundary between the Earth's crust and mantle? (2020)
  • Step 1: Understand that the Earth is made up of different layers: the crust, mantle, outer core, and inner core.
  • Step 2: Know that the boundary between the Earth's crust and mantle is called the Mohorovičić discontinuity, or Moho for short.
  • Step 3: Recognize that as you go deeper into the Earth, the temperature increases due to pressure and heat from the Earth's interior.
  • Step 4: Research or recall that the temperature at the Moho boundary is estimated to be around 1,000°C.
  • Step 5: Conclude that the approximate temperature at the boundary between the Earth's crust and mantle is 1,000°C.
