What is the basis of the scientists in dividing the Earth’s lithosphere into several plates?

• Seismicity

• Mountain formation

•   Volcanism

• All of the above      

   

What does the “Pacific Ring of Fire” tell us?

• The majority of earthquakes and volcanoes take place along the Pacific.

• A horseshoe-shaped geographic area of high volcanic and seismic activity.

• Traces some of the world’s most active volcanoes encircling the Pacific Ocean.

• All statements are correct.   

   

The following statements are true about the location of earthquakes, volcanoes, and mountain

ranges, EXCEPT:      

•   They are usually located at the edges of continents.

• Some are found in places where most volcanic eruptions occur.

• They are not randomly distributed.

• They are widely distributed in any area of the lithosphere.

All of the following are necessary precautions before an earthquake other than:

• Prepare an emergency kit for the whole family to be used during and after an earthquake.

• Keep updated on the different updates about the occurrence of earthquakes in your areas

• Stay away from possible falling debris in your location.

• Ignore precautionary measures given by authorities

With continents, earthquakes, and volcanoes are located:

• Mostly, if not entirely along the edges of the Pacific plate.

• Mostly, if not entirely in the middle of the continents

• Mostly, if not entirely along the edges of continents

• Mostly, if not entirely in the north and south poles.

   A volcano that is not expected to erupt in the future is:

• Active

• cinder

• dormant

• extinct

The method of finding the epicenter of the earthquake is called:

• Distance-Time graph

•   Seismograph

• Triangulation method

• Time difference

  All of the following statements best describe a volcano except

• A volcano can be active, dormant, and extinct.

• A volcano is usually found in the middle part of the continents.

• A volcano is a conical mountain with an opening called a crater.

• A volcano contains magma and other materials which build up its conical shape.

  All of the following are true about the location of volcanoes except

• Volcanoes are randomly distributed

• Volcanoes are found in areas where earthquakes cease to occur.

• The majority of volcanoes are found along the edges of continents.

• Volcanoes are formed along the boundaries between two lithospheric plates.

Which of the following is an active volcano in the Philippines?

• Mt.  Apo in Davao

• Mt. Bud Datu in Sulu

• Mt. Isarog in Camarines Sur

• Mt. Kanlaon in Negros Oriental
