Natural Disasters

What is the primary cause of earthquakes?

• Global warming

• Volcanic eruptions

• Meteorite impact

• Movement of tectonic plates

How are tornadoes different from hurricanes?

• Tornadoes form over land, while hurricanes form over warm ocean waters.

• Tornadoes only occur in coastal areas, while hurricanes occur inland.

• Tornadoes are smaller in size, while hurricanes are larger in size.

• Tornadoes form in cold weather, while hurricanes form in hot weather.

What are the categories used to measure the strength of hurricanes?

• Saffir-Simpson Hurricane Wind Scale

• Beaufort Scale

• Fujita Scale

• Richter Scale

What are the main causes of floods?

• Heavy rainfall, dam failure, snowmelt, and storm surges are the main causes of floods.

• Tornadoes

• Earthquakes

• Volcanic eruptions

What are the warning signs of a volcanic eruption?

• Decreased seismic activity

• Increase in wildlife population

• Increased seismic activity

• Lack of rain

How do wildfires spread?

• By the use of fire extinguishers

• By heavy rainfall and flooding

• By the deliberate actions of firefighters

• By the ignition of dry vegetation, wind, and topography.

What are the safety measures to take during an earthquake?

• Drop, Cover, and Hold On

• Run outside immediately

• Hide under a heavy object

• Stand near a window

What are the key differences between a pyroclastic flow and a lava flow during a volcanic eruption?

• Pyroclastic flow is fast-moving and consists of hot gas and volcanic materials, while lava flow is the slow movement of molten rock.

• Pyroclastic flow is the slow movement of molten rock, while lava flow is fast-moving and consists of hot gas and volcanic materials.

• Pyroclastic flow is slow-moving and consists of cold gas and volcanic materials, while lava flow is the fast movement of molten rock.

• Pyroclastic flow is cold and consists of water and ice, while lava flow is the fast movement of molten rock.

What are the factors that contribute to the formation of a tornado?

• Heavy rainfall and low wind speed

• Sunny weather and calm winds

• Warm, moist air colliding with cold, dry air and strong wind patterns

• Extreme cold temperatures and high humidity

How can individuals prepare for a hurricane?

• Stock up on perishable food items and water

• Create an emergency kit, make a family communication plan, secure your home, and stay informed about the storm's progress.

• Open all windows and doors to let the wind pass through

• Ignore all warnings and continue with normal activities
