• shearing

• folding

• tension

What type of stress results from rocks being stretched?

What is the result when stress that has accumulated along a fault is suddenly released?

• a mountain

• an earthquake

• a ridge

• The stress just builds

What is the name of the pressure that builds over time along a fault?

• stress

• strain

• seismic waves

• earthquakes

How do scientists predict earthquakes?

• Earthquakes happen at regular intervals, so scientists keep records and check the calendar.

• Scientists use a device called a seismograph to forecast earthquakes based on rumblings beneath Earth's surface.

• Scientists measure seismic waves before they turn into earthquakes.

• Scientists cannot predict earthquakes. They can only determine where earthquakes are most likely to happen based on past experience.

What is the relationship between accumulated stress along a fault and earthquakes?

• Earthquakes cause stress to accumulate along a fault.

• Earthquakes are caused when stress that has accumulated along a fault is suddenly released.

• Earthquakes are a type of stress that accumulates along faults.

• Earthquakes are completely unrelated to stress along a fault.
