Why fossil fuel can't be found in hilly area?

Fossil fuels are typically found in low-lying areas because they are formed by soil pressure, which is only possible in large amounts in these areas.

I hope it was helpful.

Fossil fuels cannot be found in hilly areas because the geological conditions necessary for the formation of fossil fuels, such as coal, oil, and natural gas, are typically not present in those areas. Fossil fuels are formed from the remains of plants and animals that were buried under layers of sediment millions of years ago. These remains undergo heat and pressure over time, transforming into fossil fuels. Hilly areas often lack the depositional environments, such as swamps and marine basins, where organic matter accumulates and gets buried deeply enough for fossil fuel formation to occur. Additionally, the geological processes that lead to the accumulation and preservation of organic matter are more commonly found in flat, low-lying areas rather than hilly terrain.
