Periodic Test in Science 7

Scientists discovered the presence of a fault. After reviewing the records of occurrences of earthquakes, they found out that the fault has not experienced any geologic activity in the last 10,000 years. What type of fault is this?

• Active fault

• Inactive fault

• Reverse fault

• Normal fault

What fault plane is nearly vertical, and the movement is predominantly lateral along the fault plane?

• Reverse Fault

• Normal Fault

• Strike-slip fault

• Oblique Fault

What fault plane is inclined at an angle less than 45 degrees from the horizontal, and the hanging wall moves upward relative to the foot wall?

• Normal fault

• Reverse Fault

• Strike-slip fault

• Thrust Fault

What type of fault is associated with horizontal movement, where two blocks side past one another?

• Strike-slip Fault

• Normal Fault

• Reverse Fault

• Dip-Slip Fault

Which scale estimates the total energy released by an earthquake?

• Seismogram

• Seismograph

• Richter Magnitude scale

• PHILVOLCS earthquake Intensity scale

Which type of fault is most commonly associated with compressional stress and is typically found in regions of mountain building?

• Strike-slip Fault

• Normal Fault

• Reverse Fault

• Transform Fault

Which of the following best describes the epicenter of an earthquake?

• The point on the Earth's surface directly above the focus.

• The deepest point within the Earth is where the seismic energy is released.

• The point within the Earth where the fault rupture begins.

• The area where the ground shakes is most intense.

An intensity IV earthquake is considered______.

• Moderately strong

• Strong

• Very strong

• Weak

A geologist observes a fault where the hanging wall has moved downward relative to the footwall at an angle of 60°. Which of the following best classifies this fault, and what is the primary stress responsible for its formation?

• Strike-slip fault; shear stress

• Reverse fault; compressional stress

• Normal fault; tensional stress

• Thrust fault; compressional stress

What is the primary factor that determines the magnitude of an earthquake?

• The depth of the earthquake's focus.

• The distance from the epicenter to the affected area.

• The amount of energy released by the seismic event.

• The type of fault is responsible for the earthquake.
