A visual explanation of methane.
The air in the atmosphere is a mixture of gases. Most of the atmosphere is nitrogen (80%) with around 20% oxygen and other trace gases.
Human activities use resources from the Earth. Many of these resources are finite, they will eventually run out.
Many human activities release polluting gases into the atmosphere, such as farming animals for food, burning fossil fuels and deforestation.
Composite materials are made from two or more different types of material by a chemical process.
Polymers can be natural or synthetic. Synthetic polymers are known as plastics.
A metal higher up in the reactivity series will displace a less reactive metal from its compound. These displacement reactions can be predicted from the reactivity series.
