C Correct answer
Explanation

Coal is a combustible sedimentary rock formed from ancient plant matter, making it a classic example of a fossil fuel.

Multiple choice
  1. anthracite

  2. peat

  3. lignite

  4. bituminous

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

Anthracite is the highest rank of coal, containing the highest carbon content and the lowest moisture/impurities, making it the cleanest burning form of coal.

Multiple choice
  1. Gasoline Pumps

  2. Water

  3. Salt

  4. Gasoline

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

Gasoline is a liquid fuel derived from the refining of crude oil, which is petroleum. Water and salt are natural inorganic substances, and gasoline pumps are equipment used to dispense fuel, not the material itself.

Multiple choice
  1. Anthracite, Bituminous and Lignite

  2. Anthracite ,Bituminous coal,LPG

  3. Kerosene, petrol, gas

  4. Coal tar,Coke,natural gas

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

Coal is classified into different ranks based on its carbon content and maturity, with the three main varieties being anthracite, bituminous, and lignite. Other options include substances like LPG or kerosene, which are petroleum products, not coal types.

Multiple choice
  1. anthracite

  2. peat

  3. bituminous

  4. lignite

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

Anthracite is the highest rank of coal, having undergone the most intense heat and pressure over the longest period. This process increases its carbon content and density compared to younger coals like peat or lignite.

Multiple choice
  1. anthracite

  2. peat

  3. lignite

  4. bituminous

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

Anthracite is considered the rarest form of coal because it requires specific geological conditions to form, resulting in a high-quality, hard, and shiny coal. Other types like lignite and bituminous are much more abundant.

Multiple choice
  1. A type of oil.

  2. A chemical compound made from oil.

  3. Oil.

  4. A hydrocarbon.
