Natural Hazards and Disasters Ch (6) Practice Quiz in English Part 1 || Class 11 Geography Book -2 Practice Quizzes in English

Explanation: Tsunamis are giant waves caused by earthquakes or volcanic eruptions that displace large volumes of ocean water.  

Explanation: Tsunamis primarily cause damage to coastal areas, destroying infrastructure, settlements, and resulting in loss of life. They do not typically lead to the formation of mountains.  

Explanation: Natural disasters are classified into categories based on their origin or cause. The main types are atmospheric (e.g., cyclones, tornadoes), aquatic (e.g., tsunamis, floods), terrestrial (e.g., earthquakes, landslides), and biological (e.g., epidemics, insect infestations). Technological disasters are caused by human activities and are not considered natural disasters.  

Explanation: A natural hazard is a potential threat that exists in the environment, while a natural disaster is the actual occurrence of that threat causing significant damage and disruption.  

Explanation: Tropical cyclones derive their energy from the latent heat released when water vapor in moist air condenses.  

Explanation: Natural disasters cannot be prevented, so the best way to deal with them is through mitigation and management strategies to minimize their impact.  

Explanation: India’s vast geographical area, environmental diversities, and large population contribute to its vulnerability to various natural disasters.  

Explanation: Natural disasters are caused by forces of nature that are largely outside of human control.  

Explanation: Natural disasters are classified into categories based on their origin or cause. The main types are atmospheric (e.g., cyclones, tornadoes), aquatic (e.g., tsunamis, floods), and terrestrial (e.g., earthquakes, landslides). Extraterrestrial disasters, such as those caused by asteroid impacts, are not included in the main categories.  

Explanation: Earthquakes are known for their unpredictable nature and potential to cause widespread destruction.  

Explanation: Tectonic earthquakes, caused by the movement of Earth’s tectonic plates, are the most devastating type of earthquake.  

Explanation: Natural disasters often result in loss of life, damage to property, and disruption of social systems. They do not typically lead to world peace.  

Explanation: Natural hazards are elements in the natural environment that have the potential to cause harm to people or property, such as volcanic eruptions, tsunamis, and landslides. Industrial accidents are caused by human activities and are not considered natural hazards.  

Explanation: The energy of a tsunami wave increases as it approaches the coast, resulting in greater devastation in coastal areas.  

Explanation: The Bhopal Gas Tragedy was a major industrial accident caused by human error, making it a human-made disaster. Landslides, floods, and volcanic eruptions are natural hazards.  

Explanation: Disasters often cause widespread damage and disruption, requiring significant mobilization of resources and efforts to respond to the event.  

Explanation: Human activities such as deforestation, unscientific land use, and construction in fragile areas can increase the risk and intensity of natural disasters like landslides and floods. Planting trees is a beneficial activity that helps to prevent soil erosion and landslides.  

Explanation: The Yokohama Strategy and Plan of Action for a Safer World was adopted at the World Conference on Natural Disaster Reduction in 1994 as a guide to reduce losses due to natural disasters.  

Explanation: Tropical cyclones are intense low-pressure systems characterized by strong winds rotating around a central core.  

Explanation: The Himalayan region, including states like Jammu and Kashmir, Himachal Pradesh, Uttarakhand, and the northeastern states, is highly vulnerable to earthquakes due to the ongoing collision of the Indian and Eurasian tectonic plates.
