Which of the following is a non-renewable energy source that is formed from the remains of ancient organisms over millions of years?
- Solar Energy
- Wind Energy
- Coal
- Geothermal Energy
Show answer
Answer: C. Coal
Coal is a fossil fuel, formed from the decomposition of plant matter over geological time, making it a non-renewable resource. Solar, wind, and geothermal energy are all renewable.
Which of the following minerals is a key component in the production of cement and also used in agriculture as a fertilizer?
- Mica
- Limestone
- Gypsum
- Feldspar
Show answer
Answer: B. Limestone
Limestone (calcium carbonate) is a crucial raw material in the manufacturing of cement. It is also used in agriculture to neutralize soil acidity and as a source of calcium.
Which of the following metals is extracted from its ore through a process called smelting, which involves heating the ore with a reducing agent like carbon at high temperatures?
- Aluminum
- Copper
- Gold
- Uranium
Show answer
Answer: B. Copper
Copper ores are commonly smelted with carbon to extract the metal. Aluminum extraction (Bayer process and electrolysis) and gold extraction (cyanidation or amalgamation) utilize different primary processes. While uranium is processed, 'smelting' is most directly associated with metals like copper and iron.
The process of using sunlight to directly heat water or air for domestic and industrial purposes is known as:
- Photovoltaic Power Generation
- Solar Thermal Heating
- Concentrated Solar Power (CSP)
- Solar Desalination
Show answer
Answer: B. Solar Thermal Heating
Solar thermal heating systems use sunlight to directly heat a fluid, such as water or air, for immediate use. Photovoltaic systems generate electricity, and CSP concentrates solar energy for higher temperatures.
Which metallic mineral is primarily mined for its use in electrical wiring, plumbing, and as an alloy in brass and bronze?
- Iron
- Aluminum
- Copper
- Zinc
Show answer
Answer: C. Copper
Copper is highly conductive and malleable, making it ideal for electrical applications. It is also used in alloys like brass and bronze. While zinc is used in galvanizing and brass, copper is the primary metal for wiring and plumbing.
