Answer:

peat, lignite, sub-bituminous, bituminous, anthracite

Explanation:

1. Peat -  a. Highest burial depths and lowest temperature less than 0.2km and 0 - 25°C,

2. Lignite - b. Slightly deeper burial depth and higher temperature 0.2–1.5 km and 25 – 40°C,

3. Sub-bituminous Coal precursor- c. Even deeper burial depth and higher temperature 1.5 – 2.5 km and 45 - 75°C,

4. Bituminous - Even deeper burial depth and higher temperature 2.5 – 6 km and 75 - 180°C,

5. Anthracite- d. Deepest burial depth and highest temperature, greater than 6 km, and greater than 180 degrees Celsius

Considering the geographical analysis, the coal and precursor in order of formation from lower burial depths and temperatures to higher begins with Peat -- Lignite -- Sub-bituminous-- Bituminous -- Anthracite.

This is explained below based on their temperatures and distance below grounds.

  • Peat => Highest burial depths and lowest temperature less than 0.2km and 0 - 25°C;

  • Lignite => Slightly deeper burial depth and higher temperature 0.2–1.5 km and 25 – 40°C;

  • Sub-bituminous Coal precursor => Even deeper burial depth and higher temperature 1.5 – 2.5 km and 45 - 75°C;

  • Bituminous => Even deeper burial depth and higher temperature 2.5 – 6 km and 75 - 180°C;

  • Anthracite => Deepest burial depth and highest temperature, greater than 6 km, and greater than 180 degrees Celsius.

Hence, in this case, it is concluded that the correct order of answers is "Peat -- Lignite -- Sub-bituminous-- Bituminous -- Anthracite."
