Question

One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible after effects. Earthquakes are the result of forces deep within the earth’s interior that continuously affects the surface of the earth. The energy from these forces is stored in a variety of ways within the rocks. When this energy is released suddenly, an earthquake occurs. The area of the fault where the sudden rupture takes place is called the focus or hypo-centre of the earthquake. The point on the earth’s surface directly above the focus is called the epicentre of the earthquake. The effect of an earthquake on the earth’s surface is called the intensity. The intensity scale consists of a series of responses such as the number of people who woke up, movement of furniture, damage to chimneys and finally total destruction. The magnitude of 5.3 might be a moderate earthquake, and a strong earthquake might be rated with the magnitude 6.3. An earthquake in a densely populated area which results in many deaths may have the same magnitude but acts only as a shock in a remote area that does nothing more than frightening the wildlife.

The passage deals with:
a) the magnitude of earthquakes
b) the causes of earthquakes
c) the effect of earthquakes
d) the cause and effect of earthquakes
