Natural Hazards and Their Impact on Human Life

Natural hazards, resulting from Earth's processes, pose significant risks to humans, affecting populations and driving migrations. These hazards include earthquakes, tsunamis, and more. Human activities can exacerbate some hazards, like floods and fires. Hazards can be local or global, with interconnected impacts. While humans can't eliminate hazards, they can mitigate effects through preparedness, improved construction, and warning systems. Earth science literacy is crucial for reducing risks and promoting informed policies.

Which of the following is NOT considered a natural hazard?

• Hurricanes

• Tornadoes

• Earthquakes

• Traffic accidents

Which natural hazard can be caused by lightning?

• Floods

• Forest fires

• Volcanic eruptions

• Earthquakes

How can human activities increase the risks from natural hazards?

• By reducing the frequency of natural events

• By contributing to the frequency and intensity of some hazards

• By eliminating natural hazards

• By making natural hazards less severe

What can drive human migrations according to the video?

• Cultural festivals

• Political stability

• Tsunamis

What is an example of a local event having distant impacts?

• A drought affecting only a single farm

• A volcanic eruption in the Pacific Ocean affecting global climate

• A flood in a small town affecting only that town

• A landslide in a remote area with no human impact

What role do geoscientists play in understanding natural hazards?

• They predict the exact time of natural events

• They eliminate natural hazards

• They improve estimates of when and where hazards occur

• They prevent natural hazards from happening

What is one way humans can reduce the impact of natural hazards?

• By avoiding all natural areas

• By eliminating natural hazards

• By improving construction methods

• By ignoring high-risk locations

Why is an earth science literate public important?

• To increase the frequency of natural hazards

• To ignore the risks from natural hazards

• To promote community awareness and develop informed policies

• To eliminate natural hazards
