What is the primary role of PHIVOLCS?

• Promoting tourism around volcanic areas.

• Conducting research on the cultural impact of volcanic eruptions

• Providing geological consulting services for construction projects.

• Monitoring and providing warnings for volcanic and seismic activity.

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

Which of the following factors associated with huge volcanic eruptions may cause the decrease in the Earth’s average temperature for a few years?

• heat 

• LIGHT

• ACID RAIN

• VOLCANIC ASH

Which of the following is NOT a factors affecting the volcanoes eruptive styles?

• Amount of dissolve gas

• shield

What do you call the type of volcanic formed by accumulation of lava that oozes  

       from the volcano?

           

• Cinder

What kind of energy we can get from the interior of the earth?

           

• geothermal energy    

• hydrothermal energy

• wind energy

Arrange the step to generate electricity in geothermal power plant

1. The cooled water is pumped back into the Earth to begin the process again

2. Cooling tower cools the steam which hand it condenses back to water

3. The steam spins a turbine, which is connected to a generator that produces

     electricity.

4. When the water reaches the surface, the drop in pressure causes the water to

     turn into steam.

            5. Wells are drilled deep into the Earth to pump steam or hot water to the

               surface.

• 1,2,3,4,5                                

• 2,3,4,5,1   

• 3,4,5,1,2     

• 5, 4,3,2,1

How is geothermal energy generated from geothermal power plants?

           

• The heat from deep inside the Earth is used to produce steam to generate

                  electricity

• The heat coming from earth’s surface used to heat water or provide heat for   

                  buildings

• The heat coming from inside the earth used to heat water or provide heat for buildings

• The heat from outside the Earth is used to produce steam to produce electricity

It is the height above sea level

 

• altimeter      

• altitude   

• latitude

• longitude
