Fossil Fuels • To know what fossil fuels are, and how they formed
Fuels • See if you can unscramble the following names of fuels: - • Aocl • Sag • Cnurela • Loi • Dinw • Rewta • Lmtheragoe • Losra Coal Gas (natural) Nuclear Oil Wind Water Geothermal (heat from the ground) Solar
Fossil Fuels • Which of the mentioned fuels are fossil fuels? • Coal • Gas (natural) • Nuclear • Oil • Wind • Water • Geothermal (heat from the ground) • Solar
Fossil Fuels • The fossil fuels are coal; natural gas; and oil • They formed millions of years ago from the remains of living things • Coal was formed from plants, and oil and natural gas from sea creatures. When the living things died, they were gradually buried by layers of rock • The buried remains were put under pressure and chemical reactions heated them up, gradually changing into fossil fuels
Fossil Fuels • Fossil fuels formed millions of years ago from the remains of living things (coal from plants and natural gas and oil from sea creatures) • They were gradually buried by layers of rock which stopped them rotting
Fossil Fuels • The buried remains were put under pressure and chemical reactions heated them up, gradually changing into fossil fuels
Fossil Fuels • Some oil and natural gas was covered by cap rock which is impermeable (not letting them through). They can be removed from the ground by drilling through the rock
Worksheet • Using the fossil fuel worksheet cut out the boxes at the bottom, and stick them next to the appropriate picture
Coal was formed from dead plants that lived long ago Oil and gas were formed from tiny plants and animals that lived in the sea millions of years ago. When the plants died they were buried in mud. The mud stopped them rotting away The plants and animals fell to the seabed when they died and got buried in mud and sand. The mud stopped them rotting away More layers of the mud squashed the fossils. Heat from inside the Earth turned the mud into rock and turned the plant fossils to coal More mud buried the dead animals, turning them into oil and gas, which get stuck under a layer of cap rock, not letting them through
Uses What are the uses of oil, natural gas and coal? • Coal is used in power stations and to heat some homes • Natural gas is the gas we use for cooking and heating, and in Bunsen burners at school • Crude oil is separated into lots of different substances at oil refineries, including camping gas, petrol, diesel and kerosene (jet fuel)
Non-renewable • Why do we say fossil fuels are non-renewable? • Fossil fuels are non-renewable energy resources - once they have all been used up they cannot be replaced
