Welcome to our electrifying quiz dedicated to the incredible power of earthquakes! Are you fascinated by the tremors that shake our world and the science behind them? Then you’ve come to the right place.
Get ready to put your seismic smarts to the test with these five intriguing questions. Good luck!
Question 1: What is a foreshock?
Answer: A foreshock is a smaller earthquake that occurs before a larger main earthquake in the same area. Think of it as a warning rumble before the big event!
Question 2: What is an aftershock?
Answer: An aftershock is a smaller earthquake that happens after a larger main earthquake, usually within the same region. These can continue for days, weeks, or even months after the initial tremor.
Question 3: What is the term for the point on the Earth’s surface directly above the hypocentre?
Answer: This crucial point is known as the epicentre. It’s often where the most significant ground shaking and damage occur during an earthquake.
Question 4: What law relates the frequency of earthquakes to their magnitude?
Answer: This is described by the Gutenberg–Richter law, which states that there are many small earthquakes for every large one. It’s a fundamental relationship in seismology!
Question 5: What global belt accounts for the majority of earthquakes?
Answer: The vast majority of the world’s earthquakes (and volcanic activity) occur along The Pacific Ring of Fire. This horseshoe-shaped zone is a hotbed of tectonic plate interaction.
How did you do? Whether you aced it or learned something new, we hope you enjoyed this quick dive into the fascinating world of seismology!
