Option 4 : Neither 1 nor 2.

The correct answer is Neither 1 nor 2.

  • Polar cells are small and weak cells.
  • These cells occur between 60 - 70-degree latitude in the northern and southern hemisphere.
  • These cells act as a heat sink.
  • They move the abundant heat from the equator towards the polar regions.
  • The boundary between the warm and cold air is called the polar front.
  • The Hadley cell and polar cells are similar because they exists as a direct consequence of surface temperature.

​

      Note -​​  Polar front 1) Polar front is the boundary between the polar cell and the Ferrel cell around the 60 degree latitude in each hemisphere.

                                     2)  It arises as a result of cold polar air meeting warm tropical air.

                                     3)  According to this theory, the mid-latitude cyclones form on boundaries between warm and cold air.
