Answer 2

The world is anything but serene and still. We are all vulnerable to natural threats, both internal and external. Meteor showers, asteroids are only a few of the factors likely to pose threats to the world from space. As for the seemingly solid earth, the planet's interior has an inner core of molten elements. It surely would not be an exaggeration to call this part of the earth, which remains invisible to our eyes, "a flaming core". There also exists an atmosphere surrounding the earth, which is a "shield" against external threats. Yet, no part of the earth is immune against the effects of atmospheric forces like thunderstorms, storms, or hurricanes.

Natural hazards may strike at any time. They can cause considerable loss of life and property. Generally referred to as "natural" disasters, earthquakes, lightning, flash floods, global wildfires, acid rain, and tidal waves have different intensities and effects. What is common to all these disasters is that in just moments they can reduce a city, with all its inhabitants, to ruin. What is most important, no human being has the power to combat or prevent any of these hazards.
