Answer 1

A atmospheric hazard or natural disaster is a natural event, such as an earthquake, flood, or hurricane, which negatively affects society, either through damage to property or through loss of life. A natural hazard is a disaster that has not yet occurred. Natural events are often referred to as natural hazards when referring to the general phenomenon, but they are called natural disasters when referring to a specific event, such as the 2004 Indian Ocean earthquake and tsunami or Hurricane Katrina. If a natural event does not pose any risk to human property or lives, it is simply a natural event; hazards and disasters only occur in conjunction with human society.

The effect of atmospheric hazards on humans or atmosphere in general are many and varied.But mainly there are three type of effects called as primary, secondary and tertiry effects.

• Primary effects are the direct result of the natural disaster, such as collapsed buildings and water damage.
• Secondary effects are the result of primary effects. Examples of secondary effects include power outages due to fallen trees or damaged building and fires from broken gas lines. In these examples, the fallen trees and the damaged building would be primary effects that caused the power outages and fires (secondary effects).
• Tertiary effects are the long term effects of natural disasters. These include changes in the landscape and natural features, loss of habitat, and crop failure or reduction due to cooler temperatures or other interference
