Geothermal energy and hydropower are examples of renewable resources

because:

• they are sourced from nature.

• they can be replenished within human life span.

• they can sustain electricity to the community.

• they never harm the environment.

Malampaya is one of the fossil fuel reservoirs of the Philippines situated in the

island of Palawan. What type of fossil fuel is harnessed in it?

• coal

• coal and oil

• natural gas

• oil

Coal is one of the major types of fossil fuels. In which types of organic matter

does coal come from?

• mostly algae

• marine organisms

• dissolve minerals from rocks

• forest trees,plants and marshes

Which of the following is the first event in fossil fuel formation?

• They are then able to turn it into products we can use, such as petrol and

  diesel.

• Millions of years ago, the remains of prehistoric plants and animals were

  buried at the bottom of the Earth.

• The plants and animals remains were altered chemically by this process

  and slowly changed into crude oil and natural gas.

• The mud sediment was buried by more sediments, and it started to change

  into rock as the temperature and pressure increased.

Non-renewable energy resources are those that cannot be readily replaced

natural substance. Which of the following are examples of renewable energy?

1. coal 2. water 3. wind 4. solar energy

• 1, 2, and 3

• 1,2 and 4

• 1,3 and 4

• 2,3 and 4

The Philippines is one of the world's top producers of geothermal power. This

is because the country:

• is abundant in natural gas.

• is located along the Pacific Ring of Fire.

• has many rocky and high mountains.

• has numerous streams and rivers

Assessing the impact of plants, which of the following is TRUE about

geothermal and hydropower in terms of environmental concerns?

• Geothermal is more environment friendly than hydropower plant.

• Hydropower is more environment friendly than geothermal plant.

• Both geothermal and hydropower plants are environment friendly.

• The impact of the power plants to the environment depends on the

  situation.

Which of the following types of hydropower relies more on the natural water

flow rates, diverting just a portion of river water through turbines, sometimes

without the use of a dam or reservoirs?

• Impoundment facilities

• Pumped storage system

• Run-of-river facilities

• All of the above

Which of the following is NOT true about the impact of geothermal energy

resource to the environment?

• Geothermal power plants do not burn fuel to generate electricity, so the

  levels of air pollutants they emit are low.

• Geothermal features in national parks, such as geysers and fumaroles,

  making the site promotes sustainability.

• Most geothermal power plants inject the geothermal steam and water

  that they use back into the earth for recycling purposes.

• The construction of geothermal power plants destroys natural habitat

  disrupting ecological niche.

Which of the following are factors in generating hydropower?

I. Amount of precipitation

II. Height of the source

III. Density of substance

IV. Steepness of slope

• I, II and III

• II, III and IV

• I, and II

• I, II, III and IV
