Advertisements
Solution
Because of the movements occurring 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.
The causes of earthquakes are as follows:
- Moving the plates
- Colliding of plates
- Plates sliding one below the other
- Forming of fractures in rock layers due to tension in the interior of the earth.
- Occurring volcanic eruptions
