  2. Mantle (Aesthenosphere)
  3. Inner core
  4. Outer core

Convection occurs at the mantle of the earth.

The correct answer is: Mantle (Aesthenosphere)


    • A convection current is the movement of energy according to the change in a temperature gradient.
    • Heat moves from one place to another.
    • Convection occurs through the movement of particles.
    • The temperature difference between the upper and lower boundaries of the mantle requires heat transfer to take place.
