Question
Give reasons why an earthquake occurs.
✓

Answer

  • When the movements occur in the interior of the Earth, tremendous tension is created in the Earth’s crust.
  • When the tension goes beyond limits, the energy is released in the form of waves.
  • This results in the trembling of the earth’s surface, i.e. an earthquake occurs.

    Following are the reasons for the occurrence of an earthquake:

    • Moving of the plates
    • Colliding of the plates
    • Plates sliding one below the other
    • Forming of fractures in rock layers, due to tension in the interior of the Earth.
    • Occurring of volcanic eruption
