What are the differences between the definitions for these three words? Greenhouse effect Global warming Climate change Long term change in weather patterns The absorbing of energy by gases in the atmosphere (e.g. carbon dioxide) which keeps the Earth warmer than it would otherwise be The gradual increase in the Earth’s mean air temperature

Swap with your partner and mark them out of six Swap with your partner and mark them out of six. Any scientific point below has 1 mark. Complete their answers “in green”. Scientific points The greenhouse effect describes how carbon dioxide in the atmosphere absorbs energy from the Sun reflected off the Earth, and traps it in our atmosphere. Climate change is long-term change in our weather caused by high levels of carbon dioxide. The levels of carbon dioxide are increasing due to the burning of fossil fuels, which releases carbon dioxide into the atmosphere. Deforestation leads to fewer trees being able to remove carbon dioxide from the atmosphere. If climate change continues, the average global temperature will rise by around 5° C by 2100. Climate change will cause polar ice to melt, causing higher sea levels and flooding. Climate change will lead to more droughts and heavier rainfall. Some species may become extinct. It will be harder to grow food. Outcomes: Describe what the greenhouse effect and climate change are Explain the causes of climate change Explain the possible long term effects of climate change

Learning outcome Answer Describe what the greenhouse effect and climate change are. The greenhouse effect describes how carbon dioxide in the atmosphere absorbs energy from the Sun reflected off the Earth, and traps it in our atmosphere. Climate change is long-term change in weather patterns. Explain the causes of climate change. Climate change is caused by increasing levels of carbon dioxide. This is due to the burning of fossil fuels, which releases carbon dioxide into the atmosphere, and deforestation, which leads to fewer trees to remove carbon dioxide from the atmosphere. Explain the possible long-term effects of climate change. If climate change continues, the average global air temperature will rise by around 5°C by 2100. This will lead to melting of the polar ice, causing higher sea levels and flooding. It will also lead to more droughts and heavier rainfall, which may cause some species to become extinct and it will be harder to grow food.
