At these, rock above the fault moves downward in relation to the rock below the fault surface.

• strike-slip fault

• reverse fault

• normal fault

Rocks on either side of this type of fault move past each other without much upward or downward movement.

• strike-slip fault

• normal fault

• reverse fault

In order to pinpoint an earthquake's epicenter, scientists need data from at least _______ seismographic stations

• 2

• 3

• 4

• 5

Structures built on areas of wet soil are vulnerable to sinking or collapse during an earthquake. This is because the wet soils undergo _________________________ due to the shaking and vibration of an earthquake.

• focus

• epicenter

• magnitude

• liquefaction

These forces push on rock in opposite, but not directly opposite, horizontal directions...similar to the way the blades of a scissors push in opposite directions on a piece of paper.

• tension forces

• shear forces

• compression forces

• all of the above

Forces that squeeze rock together.

• tension forces

• shear forces

• compression forces

• all of the above

These result from compression forces.

• strike-slip fault

• reverse fault

• normal fault
