Folding, Faulting and Earthquake

How does folding affect Earth's surface?

• Folding causes the crust to buckle, and over time, to rise up and form mountains.

• Folding causes the crust to sink.

• Folding causes the crust to bend in half.

• Folding has no effect on Earth's surface.

Which type of stress occurs at divergent boundaries where plates pull apart?

• tension

• compression

• shear

what type of folding is shown in the picture

• anticline
• syncline
• monocline
• opticline

At a normal fault the ______________ is on the higher plate

• hanging wall
• footwall

At a normal fault the ______________ is on the falling plate

• hanging wall
• footwall

In a reverse fault the ______________ moves up, relative to the footwall, due to compression (pushing) between the two plates.

• fault
• footwall
• hanging wall

This is the slowest wave picked up by the seismograph

• S Wave

• Surface Wave

The point on Earth's surface directly above where an earthquake starts in the ground.

• Magnitude

• Fault

• Focus

• Epicenter

Which type of seismic waves arrive first?
