📚 GCSE OCR Geography: Glossary & Key Terminology Quick-Memorisation Guide | GCSE OCR 地理：词汇术语速记指南
Mastering geographical terminology is essential for success in GCSE OCR Geography. This guide provides clear definitions of key terms across the specification, helping you build confidence for exams and fieldwork questions.
掌握地理术语对 GCSE OCR 地理考试至关重要。本指南提供了教学大纲中关键术语的清晰定义，帮助你在考试和实地考察问题中建立信心。
1. How This Glossary Is Organised | 本词汇表的结构与用法
OCR GCSE Geography is assessed through three papers: physical geography, people and society, and geographical skills including fieldwork. Terminology appears in all three, so a glossary is only useful when each word is attached to a real place and a real process rather than learned in isolation.
OCR GCSE 地理通过三份试卷考查：自然地理、人与社会，以及包含实地考察的地理技能。术语在三份试卷中都会出现，因此词汇表只有把每个词与真实地点和真实过程绑定起来，才真正有用，孤立背诵价值有限。
Every term below follows the same three-part pattern: the word, a precise definition written in exam-appropriate language, and a hint about where it can be used. This lets you move from simply recognising a word to actually deploying it in a structured answer.
下面每个术语都遵循同样的三段式结构：术语本身、用符合考试规范的表述写成的精确定义，以及一句关于它可以用在哪里的提示。这样你就能从"认得这个词"过渡到"在结构化答案中真正用出来"。
A reliable test of memorisation is whether you can use the term in a full sentence that names a location. If you can only repeat the definition, you are working at the level of recognition, and recognition fades quickly under exam pressure.
检验记忆是否牢靠的一个办法，是看你能不能把术语放进一个提到具体地名的完整句子中。如果你只能复述定义，说明你还停留在"再认"层面，而再认在考试压力下会迅速失效。
Use the numbered sections that follow as a revision checklist. Tick each block only when you can define the terms, give a named example and explain how the term links to a process you have studied.
把后面的编号小节当作复习清单使用。只有当你能定义术语、给出具体例子，并解释该术语与你所学过程之间的联系时，才在这一块打勾。
