What I know- Earthquakes and Faults

Which of the following describes a fault?

• An energy released from the inside of the Earth

• A movement in the Earth's crust

• A break in the Earth's crust

• A rock layer

What occurs when faults move?

• Volcanic eruption

• Earthquake

• Lanslide

• Drought

Why is that not all movements along faults produce earthquakes?

• It is because the energy of the Earth causes the rocks to move is strong enough

• It is because the friction between rocks was not overcome by the energy of the Earth

• It is because there is no friction present between the rocks.

• It is because the layers of rocks were not broken.

Fault movement is always associated with earthquakes. Arrange the following events how fault movements generate earthquake.

I. Once friction is overcome, the rocks suddenly slip.

II. Ground suddenly moves and an earthquake occurs.

III. Energy from inside the Earth is necessary to make the ground move.

IV. The rocks are stuck together due to friction.

• I, II, III, IV

• II, IV, I, III

• III, IV, I, II

• IV, II, I, III

How do faults produce earthquakes?

• Energy from inside the Earth makes the ground move, once friction is overcome, a fault slips producing an earthquake.

• Rock materials from underneath go out along fault produces earthquakes.

• magma spreads beneath the rock layers producing faults.

• tectonic plates collide producing earthquakes.

Which of the following best describes a normal fault?

• both blocks slide past another.

• both blocks of the rock move upward.

• one block of rock does not move while the other moves upward

• one block of rock does not move while the other moves downward

Which of the following refer to the type of fault in which two blocks slide horizontally past each other in the opposite direction?

• strike- slip fault

• reverse fault

• normal fault

• landslide

Which of the following could be the effect on the things above the Earth's surface when faults move?

• trees will grow taller

• soil becomes thicker

• sea water level rises

• soil cracks

Which government agency is responsible for studying the movement of faults and earthquakes?

• DOH

• DepEd

• PAGASA

• PHIVOLCS

For instance, your house is near a fault, which of the following are you going to consider doing?

• inform your parents about it and evacuate immediately.

• inform the PHIVOLCS to monitor your house daily

• tell your parents to construct a big house.

• take a selfie of the fault.
