Quarter 4 Periodical Test in Science 7

Which type of fault is characterized by the hanging wall moving downward relative to the footwall due to tensional forces pulling the crust apart?

• Reverse fault

• Normal fault

• Strike-slip fault

• Thrust fault

A fault was identified where the hanging wall had shifted upward relative to the footwall due to compressional forces. What type of fault is this?

• Normal fault

• Reverse fault

• Strike-slip fault

• Transform fault

Which factor most strongly determines the amount of damage caused by an earthquake?

• The earthquake's magnitude

• The distance from the equator

• The number of nearby volcanoes

• The presence of forests nearby

Which statement best describes how earthquake magnitude affects its impact on communities?

• Higher-magnitude earthquakes always cause severe destruction.

• Lower-magnitude earthquakes are always harmless.

• The magnitude determines the energy released but not necessarily the destruction.

• Earthquake magnitude has no effect on the level of destruction.

What is the safest action to take during an earthquake if you are indoors?

• Run outside immediately to avoid falling debris

• Stand near windows to monitor outside conditions

• Drop, cover, and hold under a sturdy table

• Stay near electrical appliances for support

What type of earthquake is most likely to generate a tsunami?

• Earthquakes with shallow underwater origins

• Earthquakes occurring near mountain ranges

• Earthquakes located in desert regions

• Earthquakes with deep inland epicenters

Which factor determines whether an underwater earthquake will generate a tsunami?

• The depth and strength of the earthquake

• The time of day the earthquake occurs

• The temperature of ocean water

• The distance between the epicenter and the equator

What early warning sign often indicates a tsunami is approaching?

• A sudden rise in air temperature

• An unexpected retreat of ocean water from the shore

• Strong winds blowing inland

• The appearance of large sea birds

Which organization in the Philippines is responsible for issuing tsunami warnings?

• PAGASA

• PHIVOLCS

• NDRRMC

• DENR

After a tsunami warning is issued, what is the most important action for people living in coastal areas?

• Move to higher ground immediately

• Gather belongings before evacuating

• Stay indoors and wait for further instructions

• Monitor the water for signs of rising tides
