GEOLOGY

Detailed explanation-1: -Natural hazards are defined as environmental phenomena that have the potential to impact societies and the human environment. These should not be confused with other types of hazards, such as manmade hazards.

Detailed explanation-2: -Natural hazards are physical phenomena caused by atmospheric, water or tectonic processes that threaten people, property or the environment. They can occur within a short or long period of time.

Detailed explanation-3: -Natural hazards can be classified into several broad categories: geological hazards, hydrological hazards, meteorological hazards, and biological hazards.

Detailed explanation-4: -Natural hazards occur across different time and area scales and each is in some way unique. Tornadoes and flash floods are short-lived, violent events, affecting a relatively small area. Others, such as droughts, develop slowly, but can affect most of a continent and entire countries for months or even years.
