FAQs on Flashcards: How Tsunamis Work Flashcard - General Knowledge Encyclopedia - Class 8

1. What causes tsunamis?

Ans. Tsunamis are primarily caused by underwater geological events, such as earthquakes, volcanic eruptions, and landslides. When these events displace a large volume of water, they create waves that travel across the ocean at high speeds.

2. How fast do tsunamis travel in the ocean?

Ans. Tsunamis can travel at speeds of up to 500 to 800 kilometers per hour (about 310 to 500 miles per hour) in deep water. However, their speed decreases when they approach shallow coastal areas, leading to an increase in wave height.

3. How do tsunamis differ from regular ocean waves?

Ans. Unlike regular ocean waves, which are caused by wind and only affect the surface of the water, tsunamis involve the movement of the entire water column, from the surface to the seafloor. This characteristic allows tsunamis to travel great distances without losing energy.

4. What should you do if a tsunami warning is issued?

Ans. If a tsunami warning is issued, it's important to move to higher ground immediately and stay away from the coast. Do not wait for the first wave, as multiple waves can occur, and the first wave may not be the largest.

5. Can tsunamis be predicted?

Ans. While scientists have made significant advancements in monitoring seismic activity and ocean conditions, accurately predicting the exact time and location of a tsunami is challenging. Early warning systems can provide alerts based on detected underwater earthquakes, but not all tsunamis are preceded by significant seismic activity.
