Solutions for "fuel yielding rock crossword clue" by Letter Count
4 Letters
COAL: A combustible black or brownish-black sedimentary rock, consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
5 Letters
SHALE: A fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments of other minerals, often containing oil or gas that can be extracted.
More About "fuel yielding rock crossword clue"
The term "fuel yielding rock" most commonly refers to geological formations that naturally produce or contain combustible materials. The primary example is coal, which is a readily combustible black or brownish-black sedimentary rock, typically occurring in rock strata in layers or veins called coal beds or coal seams. Formed over millions of years from the remains of plants, coal has been a fundamental energy source globally for centuries, powering industries and generating electricity.
Another significant "fuel yielding rock" is oil shale. Unlike conventional crude oil that pools in reservoirs, oil shale contains kerogen, a solid mixture of organic chemical compounds. When heated in a process called retorting, this kerogen can be converted into shale oil, a synthetic crude oil. While less commonly extracted than traditional crude oil or natural gas, oil shale reserves represent a vast potential future energy resource, though extraction processes are more complex and resource-intensive.
Understanding these terms is crucial not only for crosswords but also for comprehending the broader landscape of natural resources and energy production. Both coal and oil shale play vital roles in discussions about fossil fuels, their extraction, and their environmental impact.
Tips For Your Next Puzzle
- Check the Letter Count: Always verify the number of letters required for the answer. This is often the quickest way to narrow down possibilities, especially for common clues like "fuel yielding rock."
- Consider Synonyms and Related Concepts: Think beyond the most obvious answer. For "fuel yielding rock," could it be a specific type of rock (e.g., peat, lignite) or a component (e.g., bitumen)? Context is key!
- Look for Cross-References: If you have intersecting words, use the letters you've already filled in from other clues. This can reveal missing letters and confirm your answer, ensuring accuracy for trickier solutions.
