Q4 Review for LT 1

You are inside a building when a strong earthquake occurs. What is the best action to take?

• Run outside as fast as possible

• Use the elevator to move to a safer floor

• Stand near a glass window for a better view

• Take cover under a sturdy table and hold on

After an earthquake, you are near the coastline and notice the ocean rapidly receding. What should you do?

• Take pictures and post them online

• Call friends to meet you at the shore

• Immediately evacuate to higher ground

• Stay and watch for unusual wave activity

You are at home when you feel a weak shaking. What should you check first after the shaking stops?

• If the neighbors are panicking

• If your phone has a good signal

• If there are emergency vehicles nearby

• If there are any gas leaks or electrical damages

What type of fault is caused by tensional and extending forces, where the hanging wall moves downward relative to the footwall?

• Normal

• Reverse

• Strike-Slip

• Transform

In which type of fault does horizontal movement occur due to shearing forces?

• Normal

• Reverse

• Dip-Slip

• Strike-Slip

Which of the following statements is true about oceanic crust?

• It is older than continental crust.

• It is primarily composed of granite.

• It is denser and thinner than continental crust.

• It does not play a role in plate tectonics.

Which of the following best describes the illustration?

• The hanging wall moves up relative to the footwall due to compressional forces.

• The hanging wall moves down relative to the footwall due to tensional forces.

• The fault blocks slide past each other with little vertical movement.

• It only occurs at divergent plate boundaries.

A student claims that plate tectonics only cause earthquakes. Which of the following correctly explains other effects of plate movement?

• Plate movement also forms mountains, volcanoes, and oceanic trenches.

• Plate tectonics do not affect Earth’s landforms.

• Weather changes are primarily caused by plate movement.

• Only earthquakes occur; volcanoes and tsunamis are unrelated.

Which instrument is used to detect and record earthquake waves?

• Seismograph

• Barometer

• Anemometer

• Richter Scale

A seismologist observes that an earthquake's P-wave arrives much earlier than the S-wave. What does this indicate?

• The earthquake's epicenter is far from the station.

• The earthquake was weak and far away.

• The earthquake occurred near the station.

• The P-wave and S-wave move at the same speed.
