📚 IGCSE CCEA Geography: Vocabulary and Terminology Quick Revision Guide | IGCSE CCEA 地理：词汇术语速记指南
Mastering subject-specific vocabulary is one of the fastest ways to boost your IGCSE CCEA Geography grade. Many mark schemes reward precise use of geographical terms, so a clear 'word bank' can turn vague answers into exam-ready explanations. This guide groups key terms by topic and gives quick memory hooks for each one.
掌握学科专用词汇是提升 IGCSE CCEA 地理成绩的最快方法之一。许多评分标准奖励准确使用地理术语，因此清晰的“词库”能把模糊答案变成符合考试要求的解释。本指南按主题整理关键术语，并为每个术语提供快速记忆线索。
1. Why Geography Terminology Matters | 为什么地理术语重要
Geography is a vocabulary-rich subject: examiners expect you to name processes, landforms, and data techniques accurately. Learning terms in topic clusters is easier than memorising an alphabetical list because you link each word to a real case study.
地理是一门词汇量很大的学科：考官希望你能准确说出过程、地貌和数据方法。按主题聚类学习术语比死记字母表更容易，因为你能把每个词与真实案例联系起来。
| Term | Quick meaning | 中文速记 |
|---|---|---|
| Physical geography | Study of natural features and processes | 自然地理：自然特征与过程 |
| Human geography | Study of people, places and human activities | 人文地理：人与活动 |
| Sustainable | Meeting today's needs without harming future generations | 可持续：满足当代，不损害后代 |
| Interdependence | Where places or systems rely on each other | 相互依赖：地区或系统互相依靠 |
| Case study | A detailed real-world example used as evidence | 案例研究：作为证据的真实例子 |
2. River Environments | 河流环境关键词
River questions often ask about processes (erosion, transportation, deposition) and landforms (waterfalls, meanders, floodplains). Learn the sequence from source to mouth, and always link each feature to a named river example where possible.
河流题常考查过程（侵蚀、搬运、沉积）和地貌（瀑布、曲流、洪泛平原）。学习从源头到河口的顺序，并尽可能将每个特征与具体河流案例联系起来。
| Term | Quick meaning | 中文速记 |
|---|---|---|
| Erosion | Wearing away of river bed and banks | 侵蚀：磨损河床和河岸 |
| Hydraulic action | Force of water breaks rocks loose | 水力作用：水力冲走岩石 |
| Abrasion | Rocks carried by river scrape the bed | 磨蚀：挟带岩石刮蚀河床 |
| Attrition | Rocks knock together and become smaller | 磨耗：岩石碰撞变小 |
| Transportation | River carries eroded material downstream | 搬运：河流携带物质向下游 |
| Deposition | River drops its load when energy falls | 沉积：能量下降时卸载泥沙 |
| Meander | A bend in a river channel | 曲流：河道弯曲段 |
| Floodplain | Flat land beside a river that floods | 洪泛平原：河流旁易泛滥的平地 |
For a quick equation, remember that river discharge is the volume of water passing a point per second: discharge increases downstream as tributaries add water.
速记公式：河流流量是每秒通过某点的水量；下游因支流汇入，流量增大。
3. Coastal Environments | 海岸环境关键词
Coastal landforms are created by erosion (cliffs, wave-cut platforms, caves, arches, stacks) and deposition (beaches, spits, bars, tombolos). Distinguish between hard and soft engineering when discussing coastal management.
海岸地貌由侵蚀（悬崖、浪蚀平台、洞穴、海蚀拱、海蚀柱）和沉积（海滩、沙嘴、沙坝、连岛沙洲）形成。在讨论海岸管理时，要区分硬工程和软工程。
| Term | Quick meaning | 中文速记 |
|---|---|---|
| Fetch | Distance of open water over which wind blows | 风区长度：风经过的开阔水面距离 |
| Swash | Water rushing up the beach after a wave breaks | 冲流：碎浪后涌上沙滩的水 |
| Backwash | Water returning down the beach to the sea | 回流：水退回海中 |
| Longshore drift | Movement of sediment along a coastline | 沿岸漂移：沉积物沿海岸移动 |
| Spit | A ridge of sand extending from the coast into the sea | 沙嘴：伸入海中的沙脊 |
| Hard engineering | Building solid structures such as sea walls | 硬工程：建造海墙等坚固结构 |
4. Weather and Climate | 天气与气候关键词
Weather is the day-to-day state of the atmosphere, while climate is the average over 30 years. Be ready to read climate graphs and explain the factors affecting temperature and rainfall.
天气是大气逐日状态，而气候是30年的平均状况。要会读气候图，并能解释影响气温和降水的因素。
| Term | Quick meaning | 中文速记 |
|---|---|---|
| Weather | Short-term atmospheric conditions at a place | 天气：短期大气状况 |
| Climate | Average weather over about 30 years | 气候：约30年平均天气 |
| Precipitation | Any form of water falling from the sky | 降水：从天空落下的任何水 |
| Condensation | Water vapour changing into liquid droplets | 凝结：水蒸气变为液滴 |
| Anticyclone | Area of high pressure bringing settled weather | 反气旋：高压带来稳定天气 |
| Depression | Area of low pressure bringing cloud and rain | 低气压：低压带来云雨 |
| Rain shadow | Dry area on the sheltered side of high relief | 雨影：高地背风侧干燥区 |
5. Ecosystems and Biomes | 生态系统与生物群系关键词
Ecosystem questions require precise food chain terms and knowledge of nutrient cycles. For CCEA, link a small-scale ecosystem with biotic and abiotic components.
生态系统题需要准确的食物链术语和养分循环知识。对CCEA而言，要把小尺度生态系统与生物和非生物组成部分联系起来。
| Term | Quick meaning | 中文速记 |
|---|---|---|
| Ecosystem | A community of living and non-living parts interacting | 生态系统：生物与非生物相互作用 |
| Biotic | Living components such as plants and animals | 生物：植物和动物等活体 |
| Abiotic | Non-living components such as soil and light | 非生物：土壤和光等非活体 |
| Producer | Organism that makes its own food, e.g. grass | 生产者：自养生物，如草 |
