A disaster is defined as a sudden event that causes widespread destruction, including loss of human life, property, and animals, as well as environmental damage.

Tsunami, cyclone, and earthquake are all geological or meteorological events occurring naturally. A terrorist attack is an intentional act of violence by humans, making it a man-made disaster.

A hurricane is a large-scale weather system, specifically a tropical cyclone, which is a natural disaster.

Disaster management is a comprehensive process that includes rescue operations to save lives, relief operations to provide immediate aid, and mitigation strategies to minimize the impact of future disasters. Therefore, all these activities are essential components of the field.

Earthquakes, floods, and cyclones are all natural phenomena that occur independently of human activity. Since all three are natural disasters, the correct choice is all of the above.

The question asks what causes a natural disaster, but the options provided (industrial effluents, deforestation, CFC release) are primarily causes of environmental degradation or man-made disasters. However, in many educational contexts, these are grouped as human-induced factors that exacerbate natural disasters.

Tsunamis are large sea waves typically triggered by sudden displacement of water. This displacement can be caused by underwater earthquakes, landslides, or volcanic eruptions.

Landslides occur when the stability of a slope is compromised. Heavy rainfall, steep terrain, and the removal of vegetation (deforestation) are all primary contributing factors to slope failure.

A tsunami is defined as a series of massive ocean waves, often caused by seismic activity, that can cause catastrophic destruction when they reach the shore.
