Mining and Energy in the Philippines

Which type of rock is formed from pre-existing rocks that have been changed by heat and pressure?

• Sedimentary

• Metamorphic

• Igneous

• Organic

Which of the following mining methods would be most suitable for extracting gold from a riverbed in the Philippines?

• Open-pit mining

• Strip mining

• Placer mining

• Shaft mining

Considering these real-life examples, why is progressive rehabilitation considered an important aspect of sustainable mining in such regions?

• It minimizes land disturbance and helps restore the land’s natural state even while mining is ongoing, reducing long-term environmental impacts

• It ensures that mining companies can extract minerals more rapidly, providing a quicker return on investment

• It leads to a reduction in labor costs by requiring fewer workers to maintain the mining site

• It allows for a more efficient use of heavy machinery, increasing overall mineral yield during extraction

Which of the following best describes how biodiversity offsetting can help in mining operations?

• Improving the efficiency of mineral extraction

• Compensating for environmental impacts by protecting other habitats

• Reducing mining waste production

• Increasing community engagement

Which mining technique would you recommend for an ore deposit that is spread across a large surface area but shallow in depth?

• Drift mining

• Open-pit mining

• Cut and fill mining

• Shaft mining

Why is it crucial to invest in green mining technology?

• To increase the production of minerals

• To enhance the mining speed

• To decrease the need for community engagement

• To reduce environmental pollution and improve sustainability

How can remote sensing contribute to the identification of mineral deposits in the Philippines?

• By increasing the extraction rate

• By identifying mineral composition through soil sampling

• By capturing satellite imagery to reveal surface alterations caused by minerals

• By performing underground surveys

What type of mineral is commonly extracted using placer mining in the Philippines?

• Iron

• Gold

• Iron

• Limestone

Which type of energy is produced by harnessing the energy of moving water?

• Biomass energy

• Geothermal energy

• Hydropower

• Wind energy

With solar photovoltaic (PV) systems becoming more widespread in rural areas and urban centers like Metro Manila and Cebu, how might this transition contribute to the country's energy independence?

• By allowing the Philippines to generate a significant portion of its electricity domestically, reducing reliance on imported fossil fuels

• By completely replacing wind energy projects like those in Ilocos Norte, even though solar power isn't available at night

• By increasing the country's carbon footprint, as solar PV systems release greenhouse gases during operation

• By primarily generating heat energy, which then requires conversion into electricity through other means.
