Questions & Step-by-Step Solutions

Which layer of the Earth is the thickest? (2023)
  • Step 1: Understand that the Earth has different layers: the crust, mantle, outer core, and inner core.
  • Step 2: Know that the crust is the outermost layer and is relatively thin compared to the others.
  • Step 3: Learn that the mantle is the layer beneath the crust and is much thicker.
  • Step 4: Recognize that the mantle extends about 2900 kilometers below the crust.
  • Step 5: Conclude that since the mantle is much thicker than the crust and other layers, it is the thickest layer of the Earth.
