Earthquakes Review 2

What are the effects of faults on Earth's surface?

• They cause compression in the rocks

• They cause tension in the rocks

• They force faults to the surface

• They slide rocks past each other

Which type of fault occurs when there is tension in the rocks?

• Strike-Slip Fault

• Normal Fault

• Reverse Fault

• Thrust Fault

Which type of fault occurs when there is compression in the rocks?

• Strike-Slip Fault

• Reverse Fault

• Normal Fault

• Thrust Fault

What is the dip angle of reverse faults?

• 30 degrees

• 90 degrees

• Less than 30 degrees

• Greater than 30 degrees

What is the dip angle of thrust faults?

• Greater than 30 degrees

• Less than 30 degrees

• 90 degrees

• 30 degrees

Which type of fault occurs when rocks slide past each other?

• Strike-Slip Fault

• Reverse Fault

• Normal Fault

• Thrust Fault

What is the hanging wall in a reverse fault?

• The wall that moves up relative to the footwall

• The wall that moves down relative to the footwall

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

• The seismic waves released on the fault line

What is the hanging wall in a normal fault?

• The wall that moves down relative to the footwall

• The wall that moves up relative to the footwall

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

• The seismic waves released on the fault line

What is the focus of an earthquake?

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

• The seismic waves released on the fault line

• The wall that moves down relative to the footwall

• The wall that moves up relative to the footwall

What is the epicenter of an earthquake?

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

• The wall that moves down relative to the footwall

• The seismic waves released on the fault line

• The wall that moves up relative to the footwall
