Types of Faults

A type of fault where rocks on either side move past each other sideways due to shearing force or stress is called:

• normal fault

• reverse fault

• strike-slip fault

A type of fault where rocks are moving away from each other due to tensional force or stress is called:

• normal fault

• reverse fault

• strike-slip fault

A type of fault where rocks are moving towards each other due to compressional force or stress is called:

• normal fault

• reverse fault

• strike-slip fault

How are faults formed?

• Faults forms due to tensional force.

• Fault forms when the energy is released that travels outward in all directions.

• Fault forms when the forces that move in different directions go beyond the elastic limit of the rock masses.

• Fault forms when there is the sudden shaking of the ground caused by the underground rock masses that suddenly shift in position.

Which of the following statements BEST explain on how faults generate earthquakes?

• The formation of fault along the rocks that results to movement of the crust.

• Human activity like tunnel construction that results in the movement of the crust.

• The lessening of the effect of friction that holds the rocks together results in the immediate slipping of rocks.

• The buildup of stress on the rocks, reaching its limit and overcoming the friction causes the sudden release of energy.
