Earthquakes and Seismic Waves starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Earthquakes and Seismic Waves.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
Describe how a tsunami can be generated by an earthquake.
Describe the main difference between P-waves and S-waves.
Describe what a fault is in the context of earthquakes.
Describe what happens to the amplitude of seismic waves as they move away from the epicenter.
Explain how scientists use seismic waves to study the interior of the Earth.
Explain what is meant by the term 'aftershock'.
Explain why buildings constructed on loose soil are more likely to be damaged during an earthquake than those on solid rock.
Explain why seismic waves change speed and direction as they travel through different layers of the Earth.
Explain why S-waves do not travel through the Earth's outer core.
If a seismograph records a P-wave at 10:00:00 and an S-wave at 10:00:20, what is the time difference between their arrivals?
If the time difference between the arrival of P-waves and S-waves at a seismic station is 40 seconds, what does this indicate about the distance to the earthquake's epicenter?
What instrument is used to detect and record seismic waves?
What is a seismogram?
