📚 IGCSE Cambridge Geography: Vocabulary & Terminology Quick-memorisation Guide | IGCSE 剑桥地理：词汇术语速记指南
Mastering the vast array of subject-specific vocabulary is one of the steepest challenges in IGCSE Cambridge Geography. Command words, physical processes, and human geography concepts often have nuanced definitions that examiners expect you to use with precision. This guide breaks down high-frequency terms into logical groups, provides vivid associations, and shares proven memory techniques to help you retain them effortlessly. Whether you are preparing for Paper 1, 2, or 4, a firm grasp of terminology will sharpen your answers and boost your confidence.
掌握大量学科专用词汇是 IGCSE 剑桥地理中最陡峭的挑战之一。指令词、自然过程以及人文地理概念往往有着微妙的定义，考官期望你能准确使用它们。本指南将高频术语按逻辑分组，提供生动的联想，并分享经过验证的记忆技巧，帮助你毫不费力地记住它们。无论你是在准备卷一、卷二还是卷四，牢固掌握术语都会让你的答案更犀利，信心更足。
1. Why Terminology Matters | 为什么术语重要
Examiners do not just look for the right idea; they look for the right term used in the right context. Saying ‘people moving from the countryside to the city’ might earn partial credit, but using ‘rural-to-urban migration’ signals deeper understanding. Accurate terminology also helps you write succinctly under time pressure and reduces the risk of vague, low-mark answers.
考官不仅寻找正确的想法，还寻找在正确语境中使用的恰当术语。说“人们从乡村搬到城市”可能得到部分分数，但使用“乡村向城市的人口迁移”则标志着更深的理解。准确的术语还能帮助你在时间压力下简洁写作，并降低给出模糊、低分答案的风险。
2. Root Words and Prefixes | 词根与前缀
Many geographical terms share Greek or Latin roots that can unlock whole families of words. ‘Geo-‘ means earth, ‘hydro-‘ means water, ‘bio-‘ means life, and ‘-graphy’ means description. Once you know that ‘lithos’ means stone, terms like lithosphere, lithology, and monolith become far less intimidating. The prefix ‘sub-‘ (under), ‘inter-‘ (between), and ‘intra-‘ (within) also appear frequently, e.g. subduction, interdependence, intra-urban.
许多地理术语共享希腊语或拉丁语词根，可以解开整个词语家族。“Geo-”表示地球，“hydro-”表示水，“bio-”表示生命，而“-graphy”表示描述。一旦你知道“lithos”表示石头，像岩石圈、岩性学和独石这样的术语就变得不那么可怕了。前缀“sub-”（在下面）、“inter-”（之间）和“intra-”（内部）也经常出现，例如俯冲、相互依赖、城市内部。
3. Physical Geography Keywords | 自然地理关键词
Abrasion (磨蚀): The wearing away of rock by particles carried by wind, water, or ice. Think of sandpaper scratching a surface – exactly what happens when a glacier drags debris across bedrock.
Abrasion (磨蚀): 由风、水或冰携带的颗粒对岩石的磨损。想象砂纸刮擦表面——这正是冰川拖曳碎屑划过基岩时发生的现象。
Attrition (磨圆): The process where transported particles collide and become smaller and rounder. Picture pebbles tumbling in a river – they chip each other into smooth spheres over time.
Attrition (磨圆): 被搬运的颗粒相互碰撞，变得更小、更圆的过程。想象河里的卵石翻滚——它们随着时间的流逝相互撞击成光滑的球体。
Hydraulic action (水力作用): The force of water itself compressing air into cracks and breaking rock apart. Visualise a wave hammering a cliff face, forcing air to explode weak points.
Hydraulic action (水力作用): 水本身的力量将空气压缩进裂缝并使岩石破裂。想象海浪锤击悬崖面，迫使空气炸开薄弱点。
4. Human Geography Keywords | 人文地理关键词
Birth rate (出生率): The number of live births per 1,000 people per year. A high birth rate often points to limited access to contraception, agricultural economies, or cultural preferences for larger families.
Birth rate (出生率): 每年每千人中的活产婴儿数。高出生率通常指向避孕手段有限、农业经济或对大家庭的文化偏好。
Death rate (死亡率): The number of deaths per 1,000 people per year. It drops when healthcare, sanitation, and nutrition improve, but can spike during epidemics or natural disasters.
Death rate (死亡率): 每年每千人中的死亡人数。当医疗保健、卫生条件和营养改善时它会下降，但在流行病或自然灾害期间会急剧升高。
Infant mortality rate (婴儿死亡率): The number of deaths of infants under one year old per 1,000 live births. This is a sensitive indicator of a country’s health system and overall development.
Infant mortality rate (婴儿死亡率): 每千名活产婴儿中一岁以下死亡的人数。这是一个国家卫生系统和整体发展水平的敏感指标。
5. Map Skills Vocabulary | 地图技能词汇
Contour lines (等高线): Lines on a map joining points of equal height. When they are close together, the slope is steep; when far apart, the slope is gentle. Remember ‘close = cliff, wide = walk’.
Contour lines (等高线): 地图上连接相同高度点的线。当它们紧密排列时，坡度陡峭；相距较远时，坡度平缓。记住“密则陡，疏则缓”。
Grid reference (格网坐标): A system of numbered squares used to locate features. A four-figure reference gives the square, while a six-figure reference pinpoints a precise spot. Always ‘read right, then up’ – think ‘along the corridor, then up the stairs’.
Grid reference (格网坐标): 一种用于定位地物的编号方格系统。四位数字坐标给出方格，六位数字坐标精确定位一个点。总是“先读右，再读上”——想想“沿着走廊走，再上楼梯”。
Scale (比例尺): The relationship between distance on the map and actual distance on the ground. A 1:50,000 scale means 1 cm on the map equals 500 m on the ground. Check if the scale is a line, ratio, or statement – they all tell the same story.
Scale (比例尺): 地图上的距离与地面实际距离之间的关系。1:50 000 的比例尺意味着地图上 1 厘米等于地面上 500 米。检查比例尺是线段式、数字式还是文字式——它们讲述的是同一个事实。
6. Weather and Climate Terms | 天气与气候术语
Weather (天气): The day-to-day condition of the atmosphere – temperature, precipitation, wind, and cloud cover. It changes hourly. Climate is the average weather over 30 years or more – ‘climate is what you expect, weather is what you get’.
Weather (天气): 大气的日常状况——温度、降水、风和云量。它每小时都在变化。气候是 30 年或更长时间内的平均天气——“气候是你预期的，天气是你得到的”。
Relief rainfall (地形雨): Rain formed when moist air is forced to rise over high land, cools, and condenses. Picture a conveyor belt of cloud climbing a mountain – the windward side is soaking wet; the leeward side stays dry (rain shadow).
Relief rainfall (地形雨): 当潮湿空气被迫上升到高地、冷却并凝结时形成的雨。想象一条云层传送带爬上山脉——迎风坡湿透；背风坡保持干燥（雨影区）。
Anticyclone (反气旋): A high-pressure system where air sinks and diverges outward. It brings clear skies, calm winds in the centre, and extremes of temperature – hot by day, cold by night. Remember ‘A’ for Anticyclone, ‘A’ for Air sinking.
Anticyclone (反气旋): 一个高压系统，空气下沉并向外辐散。它带来晴朗的天空、中心静风以及极端温度——白天炎热，夜晚寒冷。记住反气旋的“反”与空气“反”常下沉。
7. Tectonic and Geomorphological Terms | 构造与地貌术语
Plate boundary (板块边界): The edge where two tectonic plates meet. Destructive boundaries (subduction) destroy crust, constructive boundaries (divergent) create new crust, and conservative boundaries slide past each other. Link ‘constructive’ to ‘creating’ – both start with ‘c’.
Plate boundary (板块边界): 两个构造板块相遇的边缘。破坏型边界（俯冲）破坏地壳，建设型边界（离散）创造新地壳，保守型边界相互滑过。将“建设型”与“创造”联系起来——两者都与“建”相关。
Magma vs Lava (岩浆 vs 熔岩): Magma is molten rock beneath the Earth’s surface; lava is magma that reaches the surface. Memory trick: Magma is ‘M’ for ‘mineral-rich mush underground’; Lava is ‘L’ for ‘liquid on land’.
Magma vs Lava (岩浆 vs 熔岩): 岩浆是地表下的熔融岩石；熔岩是到达地表的岩浆。记忆技巧：岩浆是“地下的矿物质粥”；熔岩是“地上的液态流”。
Erosion (侵蚀): The wearing away and removal of rock and soil by natural agents like water, ice, and wind. It involves both breakdown and transportation. Think ‘Erosion Exports Earth’ – all three start with ‘E’.
Erosion (侵蚀): 岩石和土壤被水、冰、风等自然营力磨损并搬走的过程。它同时涉及破坏和搬运。想想“侵蚀移走泥土”——三个词都有“蚀”或“移”。
8. Population and Settlement Terms | 人口与聚落术语
Population density (人口密度): The number of people per square kilometre. It is calculated as total population divided by land area. Singapore has a very high population density; Greenland has a very low one. Density does not mean total population – it is about how crowded a place feels.
Population density (人口密度): 每平方公里的人口数量。计算方式为总人口除以土地面积。新加坡的人口密度很高；格陵兰岛的人口密度很低。密度并不意味着总人口——它关乎一个地方有多拥挤。
Settlement hierarchy (聚落等级): A ranking of settlements based on size, services, and sphere of influence. From isolated dwelling to hamlet, village, town, city, and conurbation. The higher up the hierarchy, the fewer settlements there are and the greater the range of services – picture a pyramid.
Settlement hierarchy (聚落等级): 根据规模、服务和影响范围对聚落进行的排序。从独户住宅到小村落、村庄、镇、城市和组合城市。等级越高，聚落数量越少，服务范围越大——想象一个金字塔。
Urbanisation (城市化): The increase in the proportion of people living in towns and cities. It is caused by rural-to-urban migration and natural increase. In many LICs, this process is happening very rapidly, leading to the growth of megacities.
Urbanisation (城市化): 居住在城市和城镇的人口比例的增长。它由乡村向城市的人口迁移和自然增长引起。在许多低收入国家，这一过程非常迅速，导致了超大城市的发展。
9. Economic and Development Terms | 经济与发展术语
GDP per capita (人均国内生产总值): The total value of goods and services produced in a country divided by its population. It is an average measure of wealth but hides inequality. Compare it with GNI to see who actually receives the income.
GDP per capita (人均国内生产总值): 一国生产的商品和服务的总价值除以该国的总人口。它是财富的平均度量，但掩盖了不平等。将其与国民总收入比较，可以看出谁真正获得了收入。
HDI (人类发展指数): Human Development Index, a composite measure using life expectancy, education (mean years of schooling and expected years), and GNI per capita. It ranks countries from 0 to 1. ‘H’ is for Health, ‘D’ is for education Degree, ‘I’ is for Income – three dimensions in one number.
HDI (人类发展指数): 人类发展指数，一个使用预期寿命、教育（平均受教育年限和预期受教育年限）以及人均国民总收入的综合指标。它将国家从 0 到 1 排序。“H”代表健康，“D”代表学位，“I”代表收入——一个数字包含三个维度。
Informal sector (非正规部门): Jobs that are not regulated by the government, often lacking contracts, job security, and benefits. Think street vending, shoe shining, and small-scale recycling. It is not necessarily illegal but is unrecorded in official GDP.
Informal sector (非正规部门): 不受政府监管的工作，通常缺乏合同、工作保障和福利。想想街头摊贩、擦鞋和小型回收。它不一定非法，但未计入官方 GDP。
10. Environmental Management Terms | 环境管理术语
Sustainability (可持续性): Meeting the needs of the present without compromising the ability of future generations to meet their own needs. It balances three pillars: environment, society, and economy. Use the ‘three-legged stool’ analogy – remove one leg and the stool collapses.
Sustainability (可持续性): 满足当代人的需求，而不损害子孙后代满足自身需求的能力。它平衡三个支柱：环境、社会和经济。用“三条腿的凳子”类比——去掉一条腿，凳子就会倒塌。
Eutrophication (富营养化): The excessive enrichment of water bodies with nutrients (nitrates and phosphates), often from fertiliser runoff. This causes algal blooms, depletes oxygen, and kills aquatic life. Link ‘Eu-‘ (good/well) with ‘too much of a good thing’.
Eutrophication (富营养化): 水体因营养物（硝酸盐和磷酸盐）过度富集，通常来自肥料径流。这导致藻类大量繁殖、氧气耗尽并杀死水生生物。将“富”与“好过头”联系起来。
Deforestation (森林砍伐): The clearance or removal of a forest or stand of trees. Causes include logging, cattle ranching, and urban expansion. Effects include soil erosion, loss of biodiversity, and increased CO₂. Remember ‘De-‘ means ‘remove’ – deforestation removes forests.
Deforestation (森林砍伐): 清除或移除森林或树木群。原因包括砍伐、牧场经营和城市扩张。后果包括土壤侵蚀、生物多样性丧失和二氧化碳增加。记住“De-”表示“去除”——森林砍伐即去除森林。
11. Mnemonics and Visual Associations | 助记符与视觉联想
Visual and verbal mnemonics turn abstract words into something your brain already knows. For coastal erosion processes, the acronym CASH – Corrasion (abrasion), Attrition, Solution (corrosion), Hydraulic action – helps recall all four. For factors affecting population distribution, picture a WASH PILE: Water supply, Accessibility, Soil fertility, Historical factors, Political stability, Income opportunities, Lived experience, and Environment. Even silly images work: imagine a ‘meander’ as a snake ‘mean-dering’ across the landscape.
视觉和言语助记符将抽象的词语转化为你的大脑已经知道的东西。对于海岸侵蚀过程，首字母缩略词 CASH —— 磨蚀（磨蚀）、磨圆、溶蚀（溶蚀）、水力作用——有助于记住全部四个。对于影响人口分布的因素，想象一个 WASH PILE：水供应、通达性、土壤肥力、历史因素、政治稳定、收入机会、生活经历和环境。即使是可笑的图像也有效：想象“曲流”是一条蛇在景观上“蜿蜒”前行。
12. Exam Tips: Using Terminology Effectively | 考试技巧：有效使用术语
When answering structured questions, define the key term in the first sentence if the question asks for an explanation. For example, ‘Drought is a prolonged period of below-average precipitation.’ Then elaborate using case study details. Never just list terminology; embed it naturally into full sentences. In evaluation questions, comparative phrases like ‘more economically developed’ or ‘less sustainable’ show that you can apply terms in context, not just recite definitions. Finally, for the vocabulary-heavy Paper 4 Alternative to Coursework, practise writing precise descriptions and hypotheses using the correct geographical lexicon until it becomes second nature.
在回答结构化问题时，如果题目要求解释，第一句话就定义关键术语。例如，“干旱是长期低于平均降水量的时期。”然后用案例研究的细节详细说明。永远不要只是罗列术语；要自然地把它融入完整的句子中。在评价类问题中，比较性短语如“经济更发达”或“可持续性较低”表明你能在语境中应用术语，而不只是背诵定义。最后，对于词汇量要求高的卷四课程作业替代考试，要练习使用正确的地理词汇写出精确的描述和假设，直到它成为第二天性。
