I WONDER - What Is A Tsunami?

Tsunamis are caused by volcanic eruptions, earthquakes, and landslides. They consist of multiple waves, known as a wave train, rather than a single wave. The initial wave is not the strongest; waves gain speed and strength as they progress due to energy buildup over time.

What are some natural events that can trigger a tsunami?

• Blizzards, hailstorms, and thunderstorms

• Droughts, heatwaves, and wildfires

• Volcanic eruptions, earthquakes, and landslides

• Hurricanes, tornadoes, and floods

How do tsunamis typically occur?

• As a continuous flow of water

• As a sudden rise in sea level

• As a series of waves known as a wave train

• As a single massive wave

What is a wave train in the context of tsunamis?

• A series of waves that follow one another

• A wave that dissipates quickly

• A wave that circles back to its origin

• A single wave that travels long distances

Is the first wave in a tsunami usually the strongest?

• Yes, it is always the strongest

• No, it is usually weaker than subsequent waves

• It depends on the location

• It is unpredictable

What happens to the energy in a tsunami over time?

• It dissipates quickly

• It builds up, making the waves faster and stronger

• It remains constant throughout

• It decreases as the waves travel
