Natural Hazards and Disasters

What is the primary cause of earthquakes?

• Alien spacecraft landing on the earth's surface

• Global warming and climate change

• Angry gods causing the earth to shake

• Movement of tectonic plates

How are tornadoes formed?

• Tornadoes are formed from powerful thunderstorms.

• Tornadoes are formed from volcanic eruptions.

• Tornadoes are formed from earthquakes.

• Tornadoes are formed from heavy rainfall.

What are the main factors that contribute to flooding?

• Excessive sunshine

• Heavy rainfall, rapid snowmelt, inadequate drainage systems, and deforestation

• Lack of wind

• Overpopulation

Explain the process of a volcanic eruption.

• Volcanic eruptions are caused by excessive rainfall

• Volcanic eruptions are caused by the Earth's rotation

• Magma from within the Earth's mantle rises to the surface, causing pressure to build up and eventually leading to an explosive release of gases, ash, and lava.

• Volcanic eruptions occur when the moon is in a certain phase

What are the key characteristics of hurricanes?

• Tornadoes, hailstorms, drought, and potential for widespread damage

• Strong winds, heavy rainfall, storm surges, and potential for widespread damage

• Blizzards, freezing temperatures, snowfall, and potential for widespread damage

• Gentle breezes, light rainfall, calm seas, and minimal damage

How do wildfires start and spread?

• Wildfires spread through the use of fire extinguishers

• Wildfires start from a variety of sources, including human activity, lightning, and lava. They spread through the ignition of dry vegetation and can be fueled by wind and weather conditions.

• Wildfires start from the intentional burning of forests by firefighters

• Wildfires start from spontaneous combustion of wet vegetation

What are the different categories of tornadoes based on their intensity?

• Enhanced Fujita (EF) scale

• Beaufort scale

• Saffir-Simpson scale

• Richter scale

Describe the impact of flooding on the environment and human settlements.

• Flooding can cause damage to infrastructure, loss of life, displacement of people, contamination of water sources, destruction of crops, and loss of biodiversity.

• Flooding only affects human settlements, not the environment

• Flooding leads to increased biodiversity and improved water quality

• Flooding has no impact on the environment or human settlements

What are the warning signs of an impending volcanic eruption?

• Rising sea levels

• Observing ground deformation, increased seismic activity, changes in gas emissions, and changes in water and ground temperature

• Increased bird activity

• Changes in cloud formations

Discuss the measures that can be taken to prepare for and mitigate the impact of natural disasters.

• Building flimsy infrastructure and not conducting any drills

• Keeping the community uninformed about disaster preparedness

• Creating emergency plans, building resilient infrastructure, conducting regular drills, and educating the community about disaster preparedness

• Ignoring the warnings and waiting for the disaster to pass
