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 8
Describe how earthquake-resistant buildings help reduce damage during earthquakes.
Describe the difference between P waves and S waves.
Describe what a seismogram shows.
Describe what aftershocks are and why they occur.
Describe what happens at a transform plate boundary to cause earthquakes.
Explain how scientists locate the epicenter of an earthquake using seismic data.
Explain what causes most earthquakes.
A seismograph at Station A records a P wave 30 seconds before the S wave. If the average speed of P waves is 6 km/s and S waves is 3.5 km/s, estimate the distance from Station A to the earthquake epicenter.
