Question 2(a)

The destructive effects of an earthquake are far more than its constructive effects. Give reasons to support your answer.

Answer

Constructive effects of earthquakes are-

  1. Release of stored up energy of the earth
  2. Vertical and lateral displacement of the earth
  3. Formation of lakes

Destructive forces of earthquakes are-

  1. Collapse of structures causing great loss of life and property
  2. Submergence of coastal areas
  3. Changed course of rivers, rendering many areas unsuitable for irrigation and agriculture
  4. Resulting landslides disrupt the transport system
  5. Accidental fires cause damage to life and property

In geographical terminology, earthquakes are a part of endogenic forces and are regarded as constructive movements of the earth's crust but from human point of view, earthquakes are regarded as destructive causing loss of life and property.
