B. 4 m/s2
C. 16 m/s2
D. 10 m/s2
_________6. When you are holding a book, energy is stored between the book and Earth; this
type of energy is called ________ potential energy.
A. Kinetic
B. Gravitational
C. Friction
D. Elastic
________ 7. How can the speed of an object affect its kinetic energy?
A. The slower the object moves, no kinetic energy is produced.
B. The faster the object moves, the less kinetic energy is produced.
C. The faster the object moves, the more kinetic energy is produced.
D. The slower the object moves, the more kinetic energy is produced.
________8. What is the effect of the position of the object to the amount of its potential energy?
A. The higher the object, the less potential energy.
B. The higher the object, the more potential energy.
C. The lower the object, the more the potential energy.
D. The lower the object, the object has no potential energy.
________9. Gravitational potential energy depends on the ________ and ________ of the
object.
A. Height and mass
B. Mass and movement
C. Friction and movement
D. Height and weight
______ 10. On a roller coaster, where is maximum kinetic energy?

C. When going upside down
D. At the top of a big hill
________11. Among the following, which BEST describes a fault.
A. Displacement of soil along the earth’s surface
B. The scraping of fault boundaries creating seismic vibrations
C. A fracture in the earth’s surface resulting from the movement of tectonic plates
D. The movement of a fault blocks resulting from the convection currents of the
mantle
________12. Which of the following BEST describes how earthquakes are generated due to the
movement along faults?
A. Earthquakes results from the release of seismic waves.
B. Earthquakes happen when loosely packed rocks along the fault sinks.
C. As the fault blocks move, earthquakes are generated due to the release of energy.
D. Energy from inside the earth makes the ground move. Once friction is overcome, a fault
slips producing earthquake.

consider doing?
A. take a selfie of the fault.
B. tell your parents to construct a big house.
C. inform the PHIVOLCS to monitor your house daily.

B. Inactive Fault
C. Strike-slip faults
D. Oblique Fault
________16. Which illustration correctly differentiates the location of focus from its epicentre?

during an earthquake?
A. Epicenter
B. Focus
C. Fault
D. Plate
________18. Which of the following CORRECTLY describes the difference between magnitude
and intensity?
A. Magnitude accurately measures the effect of an earthquake while intensity cannot.
B. Intensity and magnitude can measure an earthquake, but intensity can accurately measure
the energy of an earthquake.
C. Intensity is a scale that measures the effect of the earthquake in the surroundings while
magnitude measures the energy in the earthquake.
D. Intensity is a scale that measures the energy in the earthquake while magnitude measures
the effect of the earthquake in the surroundings.
________19. Which of the following is NOT true about magnitude?
A. Magnitude is calculated soon after an earthquake occurred, when scientists have compared
the data from different seismograph stations.
B. Magnitude cannot be used to express how much damage an earthquake has caused.
C. Magnitude tells how much a certain area was shaken when the earthquake reached that
area
D. Magnitude describes the total amount of energy that was released by the earthquake at the
focus
