Fossil fuels

Oil and coal are examples of fossil fuels. The name fossil refers to the fact that these energy sources are made from once living organisms (ancient plants and animals) that have been fossilised and compressed underground over millions of years. This pressure leads to them changing into fuels like coal, oil, petroleum, and natural gas.


Something that is released into the environment e.g. smoke from a fire, fumes from a car.

Greenhouse gas

Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. Overall, greenhouse gases are a good thing. Without them, our planet would be too cold, and life as we know it would not exist. But there can be too much of a good thing. Scientists are worried that human activities are adding too much of these gases to the atmosphere.
