The Science Behind Ocean Waves And Tsunamis

The video explores why there are waves in the sea, focusing on wind-generated waves and tsunamis. Wind causes water displacement, creating waves whose size depends on wind strength. Tsunamis, the most destructive waves, result from sea quakes or volcanic eruptions. Despite their potential danger, waves can be enjoyed for activities like surfing.

What is the primary cause of waves in the sea?

• Tides

• Wind

• Marine life

• Sunlight

How does the strength of the wind affect the waves?

• Stronger wind makes smaller waves

• Stronger wind makes larger waves

• Wind strength has no effect on waves

• Stronger wind stops wave formation

What natural events can cause tsunamis?

• Tidal changes

• Seismic movements and volcanic eruptions

• Rainstorms

• Hurricanes

Where do the seismic movements that cause tsunamis occur?

• On the ocean surface

• At the bottom of the sea

• On mountain tops

• In the atmosphere

Why might someone enjoy waves during the summer?

• They are always calm

• They prevent swimming

• They are good for fishing

• They are fun for surfing
