Earth's natural greenhouse effect
Earth's natural greenhouse effect
A greenhouse gas is an atmospheric gas that absorbs infrared radiation emitted by Earth. It transfers energy to its surroundings and re-emits radiation, warming the surface and lower atmosphere.
Step-by-step lessons covering AQA GCSE Chemistry 9.2.1 Greenhouse gases for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
