Final answer:
Floods option (1) are an example of a natural disaster because they are severe weather-related events with significant impacts. Terrorism, fire explosions, and building collapses do not fall under the category of natural disasters as they usually result from human actions.
Step-by-step explanation:
Among the options presented, floods are an example of a natural disaster that a nurse would identify. The reason floods are classified as natural disasters is that they are extreme weather events that occur due to heavy rainfall, overflowing rivers, or other natural phenomena, resulting in significant damage to the environment, and property, and can cause loss of life.
Other natural disasters include hurricanes, earthquakes, tsunamis, and volcanic eruptions, all characterized by their uncontrollable nature and widespread impact.
In contrast, terrorism, fire explosions, and building collapses are typically a result of human actions and are not classified as natural disasters. Engineers and scientists continue to research ways to protect against, predict, and respond to natural disasters to mitigate their effects on people and property.
