7 Questions
Which scale is considered more objective and accurate based on the text?
Magnitude scale
How do scientists determine if a fault is active, as explained in the text?
Checking the country's historical records
What characterizes an inactive fault according to the text?
Faults that do not show signs of generated earthquake within the last 10,000 years
What is the point on the earth's surface directly above the focus of an earthquake called?
Epicenter
How is intensity different from magnitude in measuring earthquakes?
Intensity measures damage at a specific location, while magnitude measures energy released.
Which device is used to measure the strength of an earthquake?
Seismograph
What is the underground point of origin of an earthquake called?
Hypocenter
Study Notes
Earthquake Measurements
- The moment magnitude scale is considered more objective and accurate.
Fault Activity
- Scientists determine if a fault is active by looking for signs of recent deformation, such as offset streams, scarps, and trenches.
- An inactive fault is characterized by a lack of recent deformation or seismic activity.
Earthquake Terminology
- The point on the earth's surface directly above the focus of an earthquake is called the epicenter.
- Intensity is different from magnitude in that it measures the effects of an earthquake at a specific location, whereas magnitude measures the total energy released by the earthquake.
- Seismographs are used to measure the strength of an earthquake.
- The underground point of origin of an earthquake is called the focus.
This quiz covers key concepts related to earthquakes, including the focus and epicenter where the earthquake originates, as well as the magnitude and intensities associated with seismic events. Learn about these fundamental aspects of earthquakes and test your knowledge with this quiz.
