| What does climate change mean ? | An significant change in the earths climate over a long period |
| Natural factors that affect climate change ? | 1. Orbital changes - the way the earth moves around the sun 2. Volcanic activity 3. Solar output - amount of heat the sun gives off |
| Human factors that affect climate change ? | 1. Burning fossil fuels 2. Cement production 3. Deforestation 4. Farming |
