Final answer:
Accidents are unforeseen and unintentional events, natural causes are events caused by natural processes, and disasters are large-scale events with widespread impact.
Step-by-step explanation:
Accidents: Accidents refer to unforeseen and unintentional events that cause harm or damage. These can include car accidents, workplace accidents, or domestic accidents. Accidents are often caused by human error or negligence.
Natural Causes: Natural causes refer to events or phenomena that occur as a result of natural processes. Examples include earthquakes, hurricanes, floods, and volcanic eruptions. These events are not caused by human actions, but rather by natural forces and geological processes.
Disasters: Disasters are large-scale events that cause extensive damage and loss of life. They can be triggered by natural hazards, such as hurricanes or earthquakes, or by human activities, such as terrorist attacks or industrial accidents. In general, disasters are characterized by their widespread impact and the need for significant emergency response and recovery efforts.
