These key words relate directly to the AQA GCSE Geography specification, which aims to build students' understanding of physical geography concepts, specifically rivers, their processes, and the landscapes they create. Each term enhances students' vocabulary and knowledge, allowing them to articulate their understanding of river systems, particularly in relation to case studies such as the River Tees. This aligns with the curriculum's objectives to understand geographical processes and the environment, essential for Year 11 learners preparing for their GCSE examinations.
