| What are the three main types of pollution | Air, Soil and Water |
| What are some cause of air pollution | Smoke, dust and harmful gases |
| Where does the air pollutants come from | Cars, buses, factories |
| Smoke contains tiny particles of what | Soot |
| Why is soot dangerous for plants | Slows down photosynthesis |
| When fossil fuels are burned, what gases are released | Carbon dioxide and sulfur dioxide |
| When carbon dioxide and sulfur dioxide dissolves in rain water what is formed | Carbonic acid and sulfuric acid |
| When carbonic acid and sulfuric acid are present in rain what is it known as | Acid rain |
| Why is acid rain harmful | Affects soil pH and plant growth |
| True or False, acid rain eats away the stonework of buildings | True |
| What cause soil pollution | Pesticides, fertilisers and acid rain |
| What are pesticides | Chemicals used to kill weeds and unwanted insects |
| What are the effects of acid rain | Makes soil more acidic which affects plant growth and animals that live in soil |
| If plant growth is affected what are the consequences | All food chains begin with green plants so it will affect organisms the whole way through food chain |
| What are the causes of water pollution | Fertilisers, sewage, oil and detergents |
| When fertilisers soak into rivers and lakes it causes a green scum like growth on the surface, what is this called | Algae |
| What are the effects of an algal bloom | Blocks light from plants below and they die |
| If the plants below the surface of an algal bloom die what happens | Bacteria feed on dead leaves and use up oxygen in water which in turn kill water animals |
| Name a few examples of waste materials | Household, sewage, industrial, medical and nuclear |
| Name a few methods of waste disposal | Landfill, incineration, or dumping at sea |
| Which waste disposal method results in sulfur dioxide and other toxic gases being released in air | Incineration |
| Which waste disposal method results in the seepage of toxic materials into ground water | Landfill |
| Which waste disposal method is dumped at sea | Nuclear |
| Name some wastes that can be recycled | Paper, plastic, glass and some metals |
