Natural Disasters

What is the primary cause of earthquakes?

• Movement of tectonic plates along faults

• Alien invasions

• Global warming

• Volcanic eruptions

How are hurricanes categorized?

• Hurricanes are categorized based on their wind speed using the Saffir-Simpson Hurricane Wind Scale.

• Hurricanes are categorized based on their location

• Hurricanes are categorized based on their color

• Hurricanes are categorized based on their size

What is the difference between a tornado and a cyclone?

• Tornadoes and cyclones are the same weather phenomenon.

• Tornadoes are smaller in scale and occur over land, while cyclones are larger and typically form over oceans.

• Tornadoes are always less destructive than cyclones.

• Tornadoes are water-based, while cyclones are land-based.

What is a tsunami and how is it formed?

• A tsunami is formed when there is a sudden displacement of a large volume of water, typically due to underwater earthquakes, volcanic eruptions, landslides, or meteorite impacts.

• A tsunami is the result of a sudden increase in ocean temperature

• A tsunami is created by strong winds pushing water inland

• A tsunami is formed by excessive rainfall causing flooding

What are the effects of volcanic eruptions on the environment?

• Volcanic eruptions lead to increased biodiversity

• Volcanic eruptions only affect human settlements

• Volcanic eruptions can release ash, gases, and lava leading to air pollution, climate change, habitat destruction, and landscape alteration.

• Volcanic eruptions have no impact on the environment

How do wildfires start and spread?

• Wildfires start from a heat source like lightning or human activities and spread through dry vegetation with the help of wind and topography.

• Wildfires are caused by excessive rainfall

• Wildfires start from underwater sources

• Wildfires spread through waterlogged areas

What is the Richter scale used for?

• Determining the age of fossils

• Measuring wind speed

• Measuring the magnitude of earthquakes.

• Calculating distance between cities

What precautions can be taken to prepare for a natural disaster?

• Leave windows and doors open during the disaster

• Stock up on perishable food items

• Ignore all warnings and continue with daily activities

• Create an emergency kit, develop a family emergency plan, stay informed, secure your home, practice evacuation drills.

How do floods impact communities?

• Floods only impact the environment, not communities

• Floods impact communities by causing damage to infrastructure, homes, and businesses, leading to displacement of residents, loss of lives, disruption of essential services like water and electricity, and long-term economic consequences.

• Floods have no impact on communities

• Floods always lead to positive outcomes for communities

What is the role of early warning systems in natural disaster management?

• Early warning systems are expensive and not worth the investment

• Early warning systems are only useful after a disaster has occurred

• Early warning systems provide timely alerts and information to at-risk populations, enabling preparedness and reducing the impact of disasters.

• Early warning systems create panic among the population
