How do fossil fuels form inside of sedimentary rocks?
A
The organic material heats up as it decomposes and is compacted
B
lava heats it
C
the sun warms it
D
they weather and erode sediment
Explanation: 

Detailed explanation-1: -Sedimentary rocks and fossil fuels are related because fossil fuels are trapped in some sedimentary rocks. Fossil fuels form when organic matter and sediment accumulate on top over time. With heat and pressure, the organic matter goes through a chemical change converting them into coal, petroleum, or natural gas.

Detailed explanation-2: -Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.

Detailed explanation-3: -Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains.

Detailed explanation-4: -Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels.
