Fuels that are derived from fossils are preserved only in which kind of rocks?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Sedimentary rocks.
Fuels derived from fossils, such as coal, petroleum, and natural gas, are preserved only in sedimentary rocks. These rocks are formed by the deposition and compression of sediments over millions of years, often including the remains of plants and animals, which gradually transform into fossil fuels under heat and pressure.
Other options:
-
Volcanic rocks: Formed from cooled lava or magma; do not contain fossil fuels.
-
Metamorphic rocks: Formed by transformation of existing rocks under heat and pressure, but fossil fuels are usually destroyed in the process.
-
Plutonic rocks: Igneous rocks formed deep underground; they do not preserve organic material needed for fossil fuels.
