Introducing Earth Systems
An Earth system is an interacting network of components including the atmosphere, oceans, rocks, ice, and living organisms. Together, these various parts regulate the conditions that make life possible on our planet.
Step-by-step lessons covering OCR GCSE Chemistry Interpreting and interacting with earth systems for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Foundation Tier) or Paper 3 and Paper 4 (Higher Tier) format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
