EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Most of Earth’s coal originated as trees, ferns, and other tropical forest plants that lived in a warmer time in our history. That’s why the world’s coal beds are found on land. Oil mostly originated as very simple organisms – such as bacteria, algae and plankton.

Detailed explanation-3: -Petroleum is a fossil fuel derived from ancient fossilized organic materials, such as zooplankton and algae.

Detailed explanation-4: -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-5: -Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.
