Question 2. Give a brief account of Tsunami.
Answer:
1. Destructive and powerful sea waves are known as tsunamis.
2. Tsunamis are created at the seabed due to earthquakes with a Richter scale rating of 7 or higher, or by a volcanic eruption in the sea, or by a large landslide on the ocean floor.
3. These waves travel very quickly in a circular pattern from where they begin.
4. In the deep sea, these waves are not clearly visible because of their shorter wave heights, but when they reach coastal and shallow waters, they turn into a devastating force.
5. More than 200,000 people were affected by the very destructive tsunami that happened in the Indian Ocean on December 26, 2004.
6. With modern equipment, the prediction and a fairly exact time of a tsunami's arrival can be made. In the future, more deaths can be prevented with proper care.
7. With a tsunami warning, move to a safer location away from the coast, keep a radio handy, and follow instructions from authorities. New buildings and communities should be built considering tsunami impact.
8. Mangroves lessen the overall impact of tsunamis, so efforts should be made to increase their coverage.
In simple words: Tsunamis are huge, destructive sea waves often caused by underwater earthquakes or eruptions. They travel fast and grow dangerous near coasts, but modern tools help predict them.

Exam Tip: When describing a natural disaster, include its cause, characteristics, impact, and how it can be managed or predicted.

Question 3. What should be done at the time of gas leakage?
Answer:
1. During rescue operations, people not involved in the work should not gather around.
2. Do not enter the affected area until authorities declare it completely safe.
3. Do not participate in rescue operations without proper training and necessary equipment.

Gujarat Board Class 9 Social Science Disaster Management Additional Important Questions and Answers

A. Answer the Following Questions.

Question 1. Define and explain disaster and disaster management.
Answer:
1. A sudden incident or a natural event that causes great damage or loss of life is called a disaster.
2. Disaster management refers to many activities designed to reduce the effects of disasters and provide a system to help people at risk.
3. The organizing and managing of resources and responsibilities to handle emergencies, ensuring the safety and protection of humans, is called disaster management.
4. To handle emergencies, disaster management focuses on being ready, responding, recovering, and preventing to lessen the impact of disasters.
Explanation:
1. A disaster can be natural or man-made, catastrophic or a slow, large-scale event, possibly starting within the earth or in the atmosphere.
2. Some disasters, like volcanic eruptions, earthquakes, and tsunamis, happen due to natural causes.
3. Regardless of its type or origin, its effects can be seen over a wide area of the earth, causing destruction and taking many lives.
4. Sometimes disasters are planned to cause destruction and damage. For instance, the atomic attacks by US bombers on Hiroshima and Nagasaki in Japan during the Second World War, terrorist attacks, and riots.
5. On the other hand, some disasters occur because of human carelessness or errors. Examples include the Bhopal Gas Tragedy and the Chernobyl Atomic Disaster in Russia.
In simple words: A disaster is a sudden, harmful event that causes much damage or loss. Disaster management is all about planning, responding, and recovering from these events to keep people safe and reduce their impact.

Exam Tip: Provide a clear definition for both terms and use examples to illustrate the different types and causes of disasters, including both natural and man-made.

Question 2. State and explain the types of disasters.
Answer:
Disaster management experts have divided disasters into two categories. They are:
1. **Natural disasters:** A disaster that occurs naturally, due to forces of nature, is known as a natural disaster. For example, floods, cyclones, tsunamis, droughts, earthquakes, volcanoes, forest fires, etc.
* Among these, experts can predict disasters like floods, cyclones, tsunamis, and droughts.
* However, it is still not possible to predict disasters such as earthquakes, volcanic eruptions, and forest fires.
2. **Man-induced disasters:** A disaster caused by human carelessness, error, or sometimes intention is called a man-made disaster. For example, fires, industrial accidents, bomb explosions, riots, and terrorist attacks are man-made disasters.
In simple words: Disasters are either natural, like floods and earthquakes, or man-made, like industrial accidents or terrorist attacks. Some natural disasters can be predicted, while others, like earthquakes, cannot.

Exam Tip: Clearly differentiate between natural and man-induced disasters, providing examples for each and highlighting the predictability factor for various types of natural disasters.

Question 3. What is flood? Explain.
Answer:
1. An excess of a large amount of water beyond its normal limits, which creates several problems, is called a flood. It is a natural disaster.
2. During floods, a large area of land remains continuously submerged underwater for many days.
3. Floods are linked to heavy rainfall and rivers overflowing.
4. When it rains very heavily, rivers overflow. Water in the streets becomes trapped, and the extra water flowing into rivers starts to spill out.
5. As a result, nearby areas become submerged.
6. Floods become dangerous when certain construction activities are done without considering drainage patterns, land slopes, etc.
7. Floods cause widespread damage to lives and property.
In simple words: A flood is when too much water overflows its usual boundaries, often due to heavy rain and overflowing rivers, submerging land and causing significant damage.

Exam Tip: Explain the direct cause (heavy rainfall, overflowing rivers), the visual impact (submerged land), and the consequences (damage to life and property) to fully define a flood.

Question 4. What should we avoid during floods?
Answer:
1. One should not consume food prepared in floodwater.
2. One should not leave a safe place without gathering reliable information about safe routes and conditions.
In simple words: During floods, never eat food made with floodwater or move to unsafe areas without checking information.

Exam Tip: Focus on safety-critical actions, specifically avoiding contaminated resources and unnecessary movement, when providing advice for floods.

Question 5. Write a detailed note on cyclone.
Answer:
1. A violent storm or strong wind in which air moves very quickly in an inward circular direction is called a cyclone.
2. These severe atmospheric storms are created due to uneven atmospheric pressure, which then leads to weather disturbances.
3. These storms are known as Cyclones in the Indian subcontinent, Hurricanes and Tornadoes in the USA, and Typhoons in China and Japan.
4. Such storms or cyclones cause widespread destruction over the area they pass through.
5. In India, cyclones mainly affect the eastern coastal regions, particularly near the Bay of Bengal. Therefore, cyclones also impact Kachchh and Saurashtra.
Things that should be done during cyclone:
1. Stay continuously updated with news bulletins on TV and Radio to know the expected time of upcoming storms.
2. Those who own a radio should keep extra batteries with them.
3. Mobile phones should be kept fully charged in advance. Those with a power bank should charge it early and keep it with them.
4. Listen carefully to instructions, warnings, etc., broadcasted over the radio and follow them.
5. People should stay away from rumors.
6. Store sufficient quantities of extra food, dry snacks, and drinking water.
7. Maintain a stock of food and medicines needed for children and the elderly.
8. If the rescue team tells people to evacuate their homes, they must strictly obey and leave their homes.
9. Use clean and safe drinking water.
10. People who have taken refuge in a shelter home created by the government or any NGO should follow the rules and instructions provided.
11. They should cooperate with authorities and should not leave the premises without their instructions.
12. People should not keep domesticated animals tied to their posts. If they are free, they can defend themselves better.
Things that should not be done during cyclone:
1. Do not pay attention to gossip or rumors, except for instructions issued by the weather department on Radio.
2. If the weather suddenly calms, rain stops, and the wind becomes still, do not go into open areas, as the wind or rainfall might suddenly return.
3. Only move out if the government declares it safe.
4. Do not touch electric poles or loose wires. Keep a safe distance from them.
5. Do not seek shelter near large hoardings or big trees.
In simple words: A cyclone is a strong, swirling storm caused by air pressure differences. During a cyclone, stay informed via radio, prepare supplies, follow official orders, and avoid rumors or unsafe areas like open fields or damaged power lines.

Exam Tip: Provide a clear definition of a cyclone, mention its causes and common names in different regions, and then detail practical do's and don'ts for safety during such an event.

Question 6. What is an earthquake? Explain.
Answer:
1. A sudden, violent shaking of the ground that causes great destruction and happens due to movements within the earth's crust or volcanic action is called an earthquake.
2. Earthquakes are felt because of tectonic movements deep within the earth.
3. Earthquakes mostly happen in areas whose surface features are weak.
4. Although experts can identify earthquake-prone regions, they still cannot predict an earthquake. Since earthquakes cannot be foreseen, they cause significant damage and destruction.
In simple words: An earthquake is a sudden, strong shaking of the ground, caused by tectonic shifts or volcanic activity inside the Earth. It causes much damage because it cannot be predicted.

Exam Tip: Define an earthquake by its primary cause (tectonic movements), secondary cause (volcanic action), and emphasize the lack of predictability as a major factor in its destructive nature.

Question 7. What should be done in case of earthquake?
Answer:
1. During an earthquake, one should get under a large bench or a table. If in a school, sit under a bench.
2. If in an open space, stay away from buildings, balconies, electric power lines, and electric poles.
3. If driving a vehicle, stop it on or below a bridge, away from electric poles, power lines, and traffic signals.
4. Remain seated in your vehicle until the earthquake tremors finish.
5. Even after the earthquake tremors end, items like refrigerators, photographs on the wall, and ceiling fans might fall later due to aftershocks. So, keep a safe distance from them.
6. Keep listening to the radio for instructions and advice about the event.
7. New buildings under construction should be made earthquake-proof.
In simple words: During an earthquake, take shelter under sturdy furniture, stay clear of buildings and power lines if outside, and remain in your vehicle if driving. After tremors, be careful of falling objects and listen to official announcements.

Exam Tip: Provide clear, actionable advice for different scenarios (indoors, outdoors, in a vehicle) during an earthquake, and include post-tremor precautions.

Question 8. What should not be done during an earthquake?
Answer:
1. One should not shout or run in panic.
2. Do not try to stop objects falling down after the earthquake tremors. Trying to stop them as they fall can cause panic.
3. Do not use elevators.
4. If in a house, do not stand near wooden cabinets (cupboards), safes, mirrors, or glass chandeliers.
5. Do not light a matchstick or a lighter. Also, do not switch on electric gadgets before confirming that the cooking gas is not leaking.
6. This is done to prevent leaking gas from exploding.
7. Do not unnecessarily keep making phone calls. Too many people calling at once can overload the telephone network and jam it.
8. As a result, important calls for rescuing people, emergency care, etc., cannot be made.
9. So, only make phone calls in cases of emergency medical help, fire, or similar urgent situations.
In simple words: During an earthquake, do not panic, try to catch falling items, or use elevators. Avoid standing near heavy objects, and do not use fire or electricity without checking for gas leaks. Only make emergency calls.

Exam Tip: Clearly list actions to avoid, particularly those that increase danger (panic, using elevators, fire hazards) or hinder emergency communication.

Question 9. State the main reason that cause generation of huge tsunami waves.
Answer:
Tsunamis mainly happen due to the following reasons:
1. Large sea waves are created at the bottom of the sea due to earthquakes with a rating of 7 or more on the Richter Scale.
2. By a volcanic eruption within the sea.
3. By a large-scale landslide on ocean floors.
In simple words: Giant tsunami waves are mostly caused by strong underwater earthquakes, volcanic eruptions in the sea, or large landslides on the ocean floor.

Exam Tip: List the primary geological events that displace large volumes of water, as these are the core causes of tsunamis.

Question 10. What should and should not be done when tsunami strikes?
Answer:
Following things should be done when tsunami strikes:
1. One should immediately move to a safer place away from the seacoast upon hearing a tsunami warning.
2. One should keep a radio and mobile phone and act according to instructions received from authorities.
3. Construction of new buildings and communities should be carried out considering the tsunami impact.
4. Mangroves reduce the overall impact of tsunamis. Therefore, efforts should be made to expand mangroves.
Following things should not be done when tsunami strikes:
1. One should not take shelter in tall buildings because these buildings might collapse due to destructive waves.
2. One should not go near the sea when the tsunami settles until authorities declare it safe to visit.
In simple words: When a tsunami strikes, move quickly to higher ground, listen to official warnings, and promote mangrove growth. Do not hide in tall buildings or approach the sea until authorities say it's safe.

Exam Tip: Clearly separate "do's" and "don'ts" for tsunami safety. Emphasize immediate evacuation and obeying official directives while cautioning against unsafe shelters and premature return to coastal areas.

Question 11. Write a brief note on drought.
Answer:
1. A long period of unusually low rainfall that leads to a severe shortage of water is known as a drought.
2. Droughts happen in regions with monsoon climates where rainfall is irregular and very scarce.
3. Droughts cause much harm and destruction, and also lead to long-term effects.
4. It causes a lack of water and food, which are basic needs for living organisms.
5. Since most of India's agriculture still relies on rainwater, the effects of drought become devastating.
6. A severe shortage of water causes extensive damage to agriculture and natural vegetation.
7. In earlier times, many people used to die due to a lack of water and food.
8. However, in modern times, with quick communication, transportation, and effective management of resources, people and livestock are largely saved.
In simple words: A drought is a long time with very little rain, leading to water and food shortages. It severely impacts agriculture and life, especially in monsoon areas. Modern methods help reduce its impact compared to the past.

Exam Tip: Define drought, explain its causes in specific climates, detail its impacts on agriculture, basic needs, and historical context, and mention modern mitigation strategies.

Question 12. What should be done during droughts? What should not be done?
Answer:
Following things should be done during drought:
1. Drip irrigation in agriculture should be promoted more to save water.
2. The government should accurately assess and plan for food and water needs. It should then start rationing food and providing water as required.
3. Arrangements should be made for fair price distribution of food grains and relief work.
4. Ongoing construction activity should be stopped, except for essential work to save water.
Following things should not be done during drought:
1. Large-scale parties and celebrations should not be held. This would prevent the waste of food and water.
2. Traders or shopkeepers should not hoard or black-market food grains or fodder.
In simple words: During a drought, we should save water with drip irrigation, and the government should manage and distribute food fairly. Avoid big celebrations and stop hoarding food.

Exam Tip: For drought management, focus on water conservation methods, equitable resource distribution, and avoidance of wasteful practices or exploitation.

Question 13. What is forest fire? How does it spread?
Answer:
An uncontrolled fire happening in the forest is called a forest fire. Forest fires occur in forests and create devastation.
It spreads due to :
1. Except for forest fires caused by lightning, all other reasons for this event are man-made.
2. Throwing burning cigarette butts, bidis, or matchsticks, or leaving burning items like campfires, incense sticks, or ritual lamps, by tourists, pilgrims, or shepherds, are major human-caused reasons for forest fires.
3. Since dry leaves fallen from trees and twigs catch fire faster, there are more chances of a forest fire during a dry season after autumn.
4. After autumn, dry leaves fall and instantly catch fire even with a tiny spark. The spark then can burn the forest.
5. Moreover, the winds are also dry and contain very little humidity. Dry winds and dry leaves together act as fuel, spreading forest fire over a very large area.
6. Besides, some trees naturally release oily and flammable substances. When the fire touches such substances, it spreads even faster.
7. Once a forest fire starts, it spreads in the direction of the wind at a speed of about 15 km per hour.
8. Once a forest fire starts, if quick and effective attempts are not made to put it out, it can stop only in two cases:
* The forest fire is completely extinguished by itself, and
* Heavy rain may fall and extinguish it.
9. Along with the forest fire, smoke and sparks also rise with the air currents. These carry a great risk of starting fires in nearby settlements.
In simple words: A forest fire is an uncontrolled blaze that destroys forests. It mainly spreads due to human carelessness with fire, dry leaves and wind acting as fuel, and flammable tree substances. Once started, it's hard to stop without rain or self-extinguishing.

Exam Tip: Define forest fire, detail its common human-induced causes, explain natural factors aiding its spread (dry leaves, wind, flammable plants), and describe its rapid progression and difficulty of control.

Question 14. What should be done and not be done in case of forest fire?
Answer:
Following things should be done during forest fire:
1. People should act according to the instructions of the forest department.
2. The government should arrange special patrols in forests during dry seasons to prevent and check for forest fire occurrences.
3. Employees of the forest department should be deployed to extinguish forest fires.
Following things should not be done during forest fire:
1. While passing through a forest, one should not throw burning bidis, cigarettes, or other flammable items.
2. People living in settlements near the forest fire area should not ignore instructions from the forest department.
3. Moreover, they should inform the department if they notice any smoke or fire instances.
In simple words: During a forest fire, follow the forest department's guidance, patrol for fires, and do not discard burning items. Local residents must report any smoke or flames and adhere to official instructions.

Exam Tip: For forest fire prevention and response, focus on public cooperation with authorities, responsible behavior regarding fire sources, and active reporting of potential dangers.

Question 15. Write a brief note on industrial accidents.
Answer:
1. Industrial accidents are man-made disasters.
2. Despite several precautions and safety measures, industrial areas, townships, mills, and factories are highly prone to accidents and disasters.
3. Such accidents lead to deaths of people, livestock, and damage to property.
4. Moreover, smoke, gases, or chemicals released during such accidents also harm the environment.
5. In most cases, human errors form the basis of industrial accidents.
6. Although people take various precautions and safety measures to manage machine and production processes, collection, transfer, and distribution of raw materials and finished goods, accidents cannot be completely prevented.
In simple words: Industrial accidents are human-made disasters common in factories, causing deaths, property damage, and environmental harm, often due to human error. Even with safety measures, they cannot be entirely avoided.

Exam Tip: Highlight industrial accidents as man-made disasters, detailing their causes (human error), consequences (loss of life, property, environmental damage), and the challenge of complete prevention despite precautions.

Question 16. Give a brief idea about the Bhopal Gas Tragedy.
Answer:
1. The Bhopal Gas Tragedy happened in Bhopal, the capital city of Madhya Pradesh, on December 3, 1984.
2. The tragedy occurred at the Union Carbide India Limited factory in Bhopal, which produced insecticide.
3. Early on the morning of the accident day, a poisonous gas called methyl isocyanate (MIC), stored in large tanks, began leaking while insecticide was being produced.
4. This leakage lasted for about 40 minutes.
5. The gas spread quickly over the densely populated areas of Bhopal.
6. According to official figures, about 2500 people died, and thousands of residents in Bhopal were affected.
7. Besides people, the gas also killed thousands of birds and animals.
8. It polluted drinking water, reservoirs, and even land.
9. It also severely affected unborn babies, newborns, and pregnant women.
10. About 10,000 people became permanently disabled, and 1.5 lakh people became partially disabled. The effects of the gas leakage lasted for several years.
In simple words: The Bhopal Gas Tragedy, on December 3, 1984, was a devastating industrial accident where poisonous MIC gas leaked from an insecticide factory in Bhopal, India. It killed thousands, disabled many more, and polluted the environment for years.

Exam Tip: When describing a historical tragedy, include key facts such as the date, location, company, chemical involved, and a summary of the immediate and long-term human and environmental impact.

Question 17. What do you mean by viral diseases? How do viral epidemics affect mankind?
Answer: When many people in a wide area catch an infectious illness, it is called an epidemic. Some types of viruses cause widespread outbreaks. Viral diseases impact humans in several ways:
1. People often die because of viral diseases.
2. Viral illnesses spread more quickly and broadly than regular diseases.
3. To date, many thousands have suffered from diseases such as dengue, Ebola, swine flu, and influenza.
4. People become very scared when these diseases spread, because of the countless deaths linked to them.
5. For instance, in the past, hundreds of thousands of people suffered from plague.
6. With better treatments, new anti-viral medicines, and other drugs, the world can now largely control these serious illnesses.
7. For example, during the plague outbreak in Surat in September 1994, and more recently with swine flu and dengue, many organizations took protective actions and rescued many lives.
8. However, new viruses continue to harm people, and often, current medicines cannot manage them. This results in many deaths.
In simple words: An epidemic happens when many people in a big area get an infectious sickness. Viruses are a major cause of these outbreaks, leading to many deaths, fast spreading illnesses, and widespread fear. Although new medicines help control some, new viruses constantly appear, which existing treatments can't always stop, causing more deaths.

Exam Tip: Define epidemics and list multiple impacts of viral diseases on human life, categorizing effects like mortality, spread, fear, and historical context.

Question 18. Explain terrorist, terrorism and their acts.
Answer:
1. A person who scares people by performing acts like bombings, mass killings, and spreading fear among the public is called a terrorist.
2. The wrong and harmful actions done by such individuals or groups are called terrorism.
3. In recent times, terrorist acts have grown much more common.
4. In reality, terrorism ignores all religions, races, groups, or areas. It is generally an enemy to all people.
5. Terrorists destroy property, cause a fearful atmosphere, and achieve their goals through actions like mass killings, abductions, plane hijackings, and bombings.
6. Terrorism is now present across nearly the whole world. No nation is secure from it.
In simple words: A terrorist is someone who frightens people with violence, like bombings, to spread fear. Terrorism is the term for these harmful actions by individuals or groups. These acts have increased globally, showing no regard for religion or race, and they threaten everyone by destroying property and causing fear to meet demands.

Exam Tip: Clearly define 'terrorist' and 'terrorism' as distinct but related concepts. Then, describe various actions and global impacts to provide a comprehensive explanation.

Question 19. State the details about 9/11.
Answer:
1. On 9th September 2001 (famously known as 9/11), several self-destructive attacks happened in the USA by a terrorist group.
2. About 19 terrorists took over four passenger jets. From these, the terrorists crashed two planes into each of the Twin Towers in New York City.
3. Both towers fell to the ground in minutes. All the plane's passengers and many other people working in those towers passed away.
4. Many more people also got hurt when their homes collapsed from the falling towers.
5. A third plane crashed into the Pentagon, which is the main office of the U.S. Army, and the fourth plane crashed into a field in Pennsylvania. No one on board these planes survived.
6. This terrorist incident affected about 3000 people and left over 6000 injured.
In simple words: On September 11, 2001, terrorists crashed four hijacked planes in the USA. Two hit the Twin Towers in New York, causing them to fall and killing thousands. Another plane hit the Pentagon, and a fourth crashed in Pennsylvania, with no survivors. This attack hurt around 3000 people and injured over 6000 others.

Exam Tip: When describing historical events like 9/11, provide key dates, locations, and statistics of impact. Ensure clarity regarding the sequence of events and the scale of devastation.

Question 20. Give an account of major terrorist attacks that took place in India.
Answer:
(A) Terrorist attack on the Parliament:
1. On 13th December 2001, five terrorists from a terror group attacked the Indian Parliament building in Delhi.

12. Everyone going to work, school, or college should try to use public transport at least once a week.
13. Safety steps like wearing helmets and using seat belts should always be followed.
In simple words: To ease traffic, develop suburban areas with good public transport and create separate paths for pedestrians and cyclists. Remove road blockages and restrict slow vehicles during peak times. Educate the public on traffic rules, encourage carpooling, and complete roadwork quickly. Schedule events during off-peak hours, and drivers should stay in their lanes during jams. Build better infrastructure like highways and flyovers, promote public transport use, and always follow safety rules.

Exam Tip: Offer a diverse range of solutions, covering urban planning, infrastructure development, public awareness, behavioral changes, and adherence to safety regulations to tackle traffic issues effectively.
