15 Questions
What is the primary cause of earthquakes?
The movement of tectonic plates along fault lines
What is a seismograph used for?
Measuring the strength and details of earthquakes
What are foreshocks in relation to earthquakes?
Smaller quakes that occur prior to the mainshock
Why are geologists unable to predict when earthquakes will occur?
Activities along fault lines are unpredictable
What happens when tension builds up between tectonic plates without any movement?
Earthquakes happen due to the stress built up around fault lines
What is the primary purpose of a seismograph?
To measure the movement of ground during an earthquake
Why are foreshocks less likely to do damage than aftershocks?
Because foreshocks are smaller in magnitude
What causes aftershocks to occur many days or years after a main quake?
The transfer of energy from rocks under Earth's surface during a main quake
Why are aftershocks sometimes just as hazardous as the main quake itself?
Because they are typically stronger than the main quake
How are foreshocks and aftershocks related to earthquakes?
Foreshocks occur before an earthquake, while aftershocks occur after an earthquake
What defines a quake as a foreshock?
It is smaller in magnitude than the mainshock
How are aftershocks different from foreshocks?
Aftershocks occur after the mainshock, while foreshocks occur before
Why can't earthquakes be predicted using foreshocks?
It is impossible to tell whether a quake is a foreshock or a mainshock when it initially occurs
What causes aftershocks to occur?
The build-up of stress energy released along a fault line
How long can aftershocks last?
A few days up to years after a mainshock
