Questions Related to science & technology

Multiple choice general knowledge science & technology
  1. True

  2. False

  3. Don't Know

  4. May Be

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sulfur in coal forms sulfur dioxide (SO2) when burned, which reacts with water in atmosphere to form sulfuric acid - a major component of acid rain. This acidification harms ecosystems by acidifying lakes and soils, damaging forests and aquatic life.

Multiple choice general knowledge science & technology
  1. They are about to run out.

  2. They can be renewed over relatively short time spans.

  3. They are extremely rare.

  4. They require millions of years to renew.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Renewable resources like solar, wind, and hydro can be naturally replenished over relatively short time spans - from days to decades. This distinguishes them from fossil fuels (option D) which require millions of years to form. They are not about to run out (A), nor are they extremely rare (C).

Multiple choice general knowledge science & technology
  1. impermeable layer of rock.

  2. underground lake of oil

  3. mechanical device used to collect oil

  4. geologic environment that allows oil and gas to accumulate

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An oil trap is a geologic structure (like an anticline or fault trap) that creates a sealed environment where petroleum accumulates. It's not the impermeable rock itself (A), not an underground lake (B), and not a mechanical device (C) - it's the entire geologic setting that allows accumulation.

Multiple choice general knowledge science & technology
  1. fuel combustion for transportation

  2. automobile factories

  3. heat production for houses

  4. none of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Transportation fuel combustion (cars, trucks, planes, ships) is indeed responsible for nearly half of air pollution globally. While factories (B) and heating (C) contribute, the transportation sector is the largest single source. 'None of the above' is incorrect because A is accurate.

Multiple choice general knowledge science & technology
  1. a cheap and easily recoverable source of energy

  2. mixtures of clay and sand caombined with water and bitumen

  3. layers of sand mixed with layers of petroleum

  4. available everywhere on Earth at a depth of 4,000 feet beneath the surface

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tar sands (oil sands) are mixtures of clay, sand, water, and bitumen - a heavy, viscous form of petroleum. They are NOT cheap or easily recoverable (A) - extraction is energy-intensive and environmentally damaging. They're not simple sand-petroleum layers (C) nor found everywhere at 4000 feet (D).

Multiple choice general knowledge science & technology
  1. decreased

  2. increased

  3. remained about the same

  4. Don't Know

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to historical DOE data, U.S. renewable energy consumption actually decreased between 1997 and 2001, contrary to what might be expected. This was due to various factors including policy changes and market conditions. This question requires specific knowledge of that time period.

Multiple choice general knowledge science & technology
  1. coal

  2. bauxite

  3. diamonds

  4. gold

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Diamonds are mined most often from igneous rocks, specifically from kimberlite pipes - vertical volcanic structures that bring diamonds from deep within the Earth to the surface. Coal forms from sedimentary rocks, bauxite is weathered soil, and gold occurs in various rock types but is most famously associated with quartz veins.
