Which of the following is a natural disaster?
A. Storm
B. Cyclone
C. Flood
D. All of the above

Answer 1

Hint: Here, we will proceed by defining the term natural disaster along with its causes. Then, we will write down the various causes and effects which will be pertaining due to all the options in the given problem.

Complete step-by-step answer:
A natural disaster is a significant adverse occurrence arising from Earth's natural processes; floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, and other geological processes are examples. When an adverse incident happens in a region without a vulnerable population, it does not escalate to the point of a catastrophe.

Storm, violent atmospheric disturbance, characterized by low barometric pressure, cloud cover, snow, heavy winds and possibly thunder and lightning. Storm is a common term, popularly used to describe a wide range of atmospheric disturbances, ranging from ordinary rain showers and snowstorms to thunderstorms, wind and wind disturbances, such as gales, tornadoes, tropical cyclones, and sandstorms.

In meteorological terms, a storm is limited to a cyclone with a high low-pressure centre, powerful winds ranging from 103–117 kilometres per hour, followed by heavy precipitation, and sometimes lightning and thunder.

In meteorology, a cyclone is a large-scale air mass that rotates around a powerful low atmospheric pressure centre. Cyclones are characterized by spiralling inward winds, which rotate around a low pressure region. Polar vortices and the most extensive extratropical cyclones (the synoptic scale) are the main low-pressure systems. Also within the synoptic scale lies warm-core cyclones such as tropical cyclones and subtropical cyclones. In a smaller mesoscale live mesocyclone, tornadoes, and devils of ashes.

A flood is a stream of water that overflows the field. The EU Floods Directive describes a flood as a temporary reservoir covering the ground that is not normally covered by water. The term can also be applied to the tide's inflow in the sense of flowing water. Flooding may result from the amount of water flooding within a body of water, such as a river or lake, allowing some of the water to leave its normal boundaries. Although the size of a lake or other water source can vary with seasonal changes in precipitation and snow melting, it is not a major flood unless the water covers man-made land, such as a village, town or other populated place, roads, fields, etc.

Therefore, storms, cyclones and floods are all natural disasters.
Hence, option D is correct.

Note- A natural disaster is the one which can cause loss of life or damage to property and usually leaves some economic harm in its wake, the extent of which depends on the resilience (ability to recover) of the affected population and also on the available infrastructure.
