What is a tsunami and how is it formed?
A tsunami is a weather phenomenon caused by strong winds.
A tsunami is a series of ocean waves formed by large disturbances such as underwater earthquakes, volcanic eruptions, or landslides.
A tsunami is a single wave caused by heavy rainfall.
A tsunami is a type of fish found in the ocean.
What are the primary causes of tsunamis?
Tsunamis are a result of strong winds.
The primary causes of tsunamis are earthquakes, volcanic eruptions, and underwater landslides.
Tsunamis are caused by meteor showers.
Tsunamis are primarily caused by high tides.
How do seismic waves travel through the Earth?
Seismic waves are only generated by volcanic activity.
Seismic waves travel through the Earth by propagating as P-waves and S-waves through its layers.
Seismic waves can only travel through water.
Seismic waves only travel through the Earth's crust.
What is the difference between P-waves and S-waves?
P-waves and S-waves are both surface waves.
P-waves are slower than S-waves.
S-waves can travel through liquids and gases.
P-waves can travel through solids, liquids, and gases, while S-waves can only travel through solids.
What scale is used to measure the magnitude of earthquakes?
Richter scale or moment magnitude scale (Mw)
Fujita scale
Saffir-Simpson scale
Beaufort scale
How can tsunamis be detected before they reach land?
Tsunamis can be predicted by studying cloud patterns.
Tsunamis are detected by monitoring fish behavior.
Tsunamis can be detected using seismic sensors and deep-ocean buoys.
Tsunamis can be detected using weather satellites.
What role do tectonic plates play in earthquakes?
Tectonic plates cause earthquakes by moving and interacting at their boundaries, leading to stress buildup and sudden release.
Tectonic plates only influence weather patterns, not seismic activity.
Tectonic plates are stationary and do not affect earthquakes.
Earthquakes are caused solely by volcanic activity, not tectonic plates.
What is the impact of a tsunami on coastal communities?
Tsunamis have no effect on coastal communities.
Tsunamis can lead to loss of life, destruction of infrastructure, displacement of communities, and long-term economic challenges.
Tsunamis only cause minor flooding in coastal areas.
Tsunamis improve coastal tourism and economy.
How do scientists study and predict earthquakes?
Scientists study and predict earthquakes through seismic monitoring, data analysis, and computer modeling.
Studying historical texts about earthquakes
Using weather patterns to predict earthquakes
Analyzing animal behavior before earthquakes
What safety measures can be taken during a tsunami warning?
Go to the beach to watch the waves
Ignore the warning and continue normal activities
Stay indoors and wait for the tsunami to pass
Move to higher ground, avoid coastal areas, listen to emergency services, and prepare an emergency kit.
