1.Which of the following statement is true about earthquake? *

A. Faults form as the Earth’s crust deforms due to stress.
B. Earthquake is a matter of it and not a matter of when
C. The earth’s crust is unbroken even if there are compressions and tensions.
D. Tectonic plates do not move if rocks are stretched, compressed or crushed.

2.Which is correctly matched? *

A. strike-slip fault – the hanging wall moves upward.
B. normal fault – the hanging wall moves downward
C. reverse fault – walls move sideways not up or down
D. oblique-slip fault – walls move horizontally in opposite directions

3.Which of the following forces will happen when rocks are pulled away from each other? *

A. compression
B. parallel
C. shearing
D. tension

4.Which refers to the origin of the earthquake? *

A. epicenter
B. fault
C. fault plane
D. focus

5.Which statement best describes a fault plane? *

A. It is the location where the fault begins to slip.
B. It is the area where layers of rocks break into two.
C. It is the trace of the fault on the surface of the Earth.
D. It is the flat surface along which there is slip during an earthquake

6.Which is correct about focus and epicenter *

A. Epicenter is also called hypocenter or focus.
B. Epicenter is the point where the focus of the earthquake originates.
C. Epicenter is in the surface of the earth that is directly below the focus.
D. Epicenter is in the surface of the earth that is directly above the focus.

7.How do magnitude and intensity differ? *
A. Magnitude is determined by using Rossi-Forel Scale while intensity is measured by seismographs.
B. Magnitude uses Roman numerals (I, II, III), whereas intensity uses Hindu-Arabic numerals (2, 3, 4).
C. Magnitude is determined by observing the effects of the earthquake in people and places while intensity is calculated by the scientists based on earth’s released energy.
D. Magnitude is a quantitative measure of the energy released during the earthquake while intensity is a qualitative measure of the strength of the earthquake at a certain location

8.When an earthquake occurs, different places experience different intensities. When an earthquake happens, where should shaking be greater? *
1 point
A. near the epicenter
B. away from the epicenter
C. left of the epicenter
D. right of the epicenter

1 point
A. active fault
B. inactive fault
C. normal fault
D. reverse fault

10. How do you call the 1200 km fault zone in the country that moves across the archipelago? *

A. Central Marinduque Fault
B. Philippine Fault Zone
C. Lubang Fault
D. Valley Fault System​
