Answer 2

Tiny microscopic plants and animals float when they die. When they die their remains drift slowly to the seafloor. The water pressure pushes the remains to the Earths interior. Then the remains get melted from all the heat (which turns the remains to oil). The oil then rises into layers of rock. Then a oil rig breaks the layer of rock collecting all the oil. This procedure takes millions of years and is extremely unsafe for the enviorment.

Answer 3

Marine algae got trapped under mud. Many years later, pressure from the mud, and the stone that some of the mud became, turned the wax (the way some marine algae stores its energy) into crude petroleum.

Answer 4

fossil fuels. trees from ancient times have decayed and piled up to form peat which has been covered in layers of dirt while pressurized and heated to form coal, oil, and natural gas.

Answer 5

The Flintstones buried their pet dinosaurs all over the place and they turned into 3-in-1.

Answer 6

Noah's Flood buried all the plants and animals and they turned into coal and oil from the huge pressures of being buried quickly.
