Greenhouse Gas - GCSE Chemistry Definition

Greenhouse gases are special types of gases in the Earth's atmosphere that trap heat from the sun, keeping our planet warm enough to support life. The main greenhouse gases are carbon dioxide, methane, and water vapour. These gases prevent heat from escaping back into space by absorbing it, a bit like a blanket keeping the Earth warm. While they are natural and essential for life, human activities, such as burning fossil fuels and deforestation, are increasing the levels of these gases, leading to climate change. Understanding greenhouse gases helps us see why it's important to reduce our impact on the environment.
