1. River Processes and Landforms | 河流过程与地貌
Abrasion – The scraping and grinding action of rock fragments carried by the river against its bed and banks, working like sandpaper. Memory fix: 'Abrasion' contains 'abrasive' – think of gritty sandpaper wearing wood away.
磨蚀 – 河流携带的石块对河床和河岸进行刮擦研磨，就像砂纸打磨木头。记忆口诀：“磨蚀”本身就是“磨”损和“蚀”刻，砂纸一擦就掉一层。
Attrition – The process where rocks and pebbles smash into each other while being moved along, becoming smaller, smoother and rounder. Trick: 'At-*tri*-tion' sounds like 'try' – the stones try to break each other apart.
磨损（磨耗） – 石块在搬运过程中相互撞击、破碎，变得越来越小、越光滑、越圆。记忆法：“attrition”像“a-trit-ion”，可以想象彼此“attack”（攻击）变成碎屑。
Hydraulic Action – The force of water pushing air into tiny cracks in the riverbank; the pressure weakens the rock and breaks pieces off. Remember: 'Hydraulic' points to 'hydro' (water) power – think of a high-pressure water jet.
水力作用 – 水流把空气压进河岸的微小裂缝，空气膨胀产生的压力使岩石崩解脱落。记忆亮点：“水力”即水的力量，想象高压水枪冲开墙壁的画面。
Solution (Corrosion) – solving of soluble minerals in rocks (like limestone) by slightly acidic river water. Tip: 'Solution' = 'dissolve', exactly like sugar dissolving in tea.
溶蚀 – 微酸性的河水以化学方式溶解岩石中的可溶性矿物（如石灰岩）。记忆：糖溶于茶就是“solution”，岩石消失于水中同理。
Meander – A winding bend in a river. Water flows faster on the outside edge (erosion) and slower on the inside (deposition). Visual trick: Picture a snake meandering across the floor – it never goes straight.
曲流（河曲） – 河流的蜿蜒弯曲河段。外侧水流急，侵蚀为主；内侧水流缓，沉积为主。联想记忆：像“漫步”的蛇，弯来弯去就是不直走。
2. Coastal Landscapes and Processes | 海岸景观与过程
Longshore Drift – The zigzag movement of sand and pebbles along a beach, caused by waves hitting the shore at an angle. Swash carries material up, backwash drags it straight down. Reminder: 'Long' + 'shore' – material travels a long way along the shore.
沿岸漂移 – 波浪以一定角度冲击海岸，造成沙石沿海滩呈“之”字形移动。冲流将物质推上滩，回流将其垂直带回海中。记忆：“沿岸”就是沿着海岸线长距离漂移。
Swash – The forward rush of a wave onto the beach, carrying sand upwards. Sound-alike: 'Swash' matches 'splash' – water splashing onto the shore.
冲流（上冲流） – 波浪冲向海滩的前进水流，携带沙粒上滩。谐音记忆：“swash”听着像“splash”，水花四溅，冲到岸上。
Backwash – The backward flow of water returning to the sea after a wave breaks, pulling material down the beach. Trick: It does exactly what it says – washing *back* into the ocean.
回流（下冲流） – 波浪破碎后沿滩面流回海洋的水流，将沙粒带回海中。记忆：直接看词，“back”就是往回流。
Fetch – The distance of open water over which the wind blows to generate waves. The longer the fetch, the higher and more powerful the waves. Quick link: 'Fetch' a ball from far away – the farther it travels, the stronger the throw.
风区长度（吹程） – 风在水面上连续吹过的距离。吹程越长，波浪越高、能量越大。联想：“fetch”有去远处取东西的意思，距离远力气就大。
Cave-Arch-Stack-Stump Sequence – A classic landform progression: waves erode a crack into a cave, which breaks through a headland to form an arch, then collapses into a stack, and finally weathers down to a stump. Memory chain: C-A-S-S – 'Caves Always Start Stacks' – and eventually stumps!
海蚀洞-海蚀拱-海蚀柱-海蚀残柱序列 – 经典的海岸侵蚀地貌演变：波浪把裂缝扩大为洞穴，洞贯穿着岬角成拱，拱顶塌落成柱，柱最终风化缩减成残柱。口诀串联：洞-拱-柱-残（D-G-Z-C），想到“山洞最终只剩残骸”。
3. Weather and Climate | 天气与气候
Precipitation – Any form of water falling from the atmosphere: rain, snow, sleet or hail. Tip: Think 'precipitate' – to cause something to happen suddenly, just like rain falling out of clouds.
降水 – 从大气中降落到地面的各种形式的水，例如雨、雪、雨夹雪或冰雹。记忆法：“降”水，从天而降。
Temperature – A measure of how hot or cold the air is, usually shown in degrees Celsius (°C). Key fact: Temperature decreases as altitude increases.
气温 – 衡量空气冷热程度的指标，通常用摄氏度表示。记住规律：海拔每升高，气温就降低。
Depression (Low Pressure) – A weather system where air rises, causing clouds, rain and windy conditions. Rapid reference: When you feel 'depressed', the mood is low – just like the pressure.
低气压（气旋） – 空气上升形成的天气系统，带来多云、降雨和大风天气。联想记忆：情绪低落（depressed）对应低气压和坏天气。
Anticyclone (High Pressure) – A system of descending air that brings clear skies, dry conditions and settled weather. Opposites clue: 'Anti'-cyclone is the opposite of a cyclone (low), so it means high pressure and fine weather.
高气压（反气旋） – 空气下沉形成的天气系统，带来晴朗、干燥和稳定的天气。词根记忆：“anti”反对，与气旋相反，所以高气压好天气。
Cold Front – The boundary where a cold air mass pushes under a warm air mass, forcing warm air to rise quickly, producing heavy rain and a temperature drop. Visualise: A 'front' like a battle line – cold air advances aggressively.
冷锋 – 冷气团向暖气团推进的分界线，迫使暖气团急剧抬升，产生强降雨和降温。形象记忆：“锋”如战线，冷空气猛烈进攻。
4. Population and Migration | 人口与迁移
Birth Rate – irths per 1,000 people per year. Clear formula: (Total births ÷ total population) × 1,000.
出生率 – 每年每千人口中的活产婴儿数。简单公式：(出生人数÷总人口)×1000。
Death Rate – The number of deaths per 1,000 people per year. Easy pair: Birth rate + Death rate – they are always compared.
死亡率 – 每年每千人口中的死亡人数。与出生率成对记忆，两者常一起对比。
Natural Increase – The difference between birth rate and death rate. If births exceed deaths, population grows naturally. Memory line: 'Natural' means no migration included – it is purely births minus deaths.
自然增长 – 出生率减去死亡率的差值。如果出生多于死亡，人口自然增加。要点：这个“自然”不含迁移，纯属出生和死亡之差。
Push and Pull Factors – Push factors drive people away from an area (e.g. war, unemployment), while pull factors attract people to a new place (e.g. better jobs, safety). Trick: 'Push' your problems away, 'pull' opportunities towards you.
推力和拉力因素 – 推力因素促使人们离开某地（如战争、失业），拉力因素吸引人们迁往新地方（如更好的工作、安全）。联想：推开坏境遇，拉近好机会。
Population Density – m²). High density = crowded; low density = sparse. Formula: Total population ÷ area (km²).
人口密度 – 每平方公里居住的人口数。密度高表示拥挤，密度低表示稀疏。公式：总人口÷面积（km²）。
5. Settlement and Urbanisation | 聚落与城市化
Site – The actual land on which a settlement is built, described by its physical characteristics (flat land, near river, sheltered). Memory: 'Site' is the specific *spot* where buildings sit.
选址地（地点） – 聚落建立的实际地块，由其自然特征描述（平地、近河、避风）。记忆：“site”就是你坐下的具体“位置”。
Situation – The location of a settlement in relation to its surrounding features (e.g. 10 km from the nearest town, on a trade route). Difference from site: 'Situation' refers to its connections and surroundings.
区位（相对位置） – 聚落相对于周围地物的位置关系（如离最近城镇10公里，位于商路上）。与地点区分：“situation”侧重联系和环境。
Settlement Hierarchy – ettlements by size and importance: hamlet → village → town → city. Tip: Think of a pyramid – many small places at the bottom, few big cities at the top.
聚落等级体系 – 按规模和重要性排列的聚落序列：小村→村庄→镇→城市。金字塔记忆：底部大量小聚落，顶部少数大城市。
Sphere of Influence – The area served by a settlement or service; how far people are willing to travel to use it. Quick reminder: A big supermarket has a large 'sphere' – people come from miles around.
影响范围 – 一个聚落或服务所覆盖的区域，即人们愿意前来的最大距离。记忆点：大超市的“影响圈”大，远郊的人都来。
Urbanisation – The increase in the proportion of people living in towns and cities. Think 'urban' = city, so urbanisation is the process of a population becoming more city-based.
城市化 – 居住在城市和城镇的人口比例增加的过程。词根：urban（城市）＋isation（过程），即变城市化的过程。
6. Map Skills and Ordnance Survey | 地图技能与地形图
Contour Lines – al height above sea level. Close contours = steep slope; wide apart = gentle slope. Trick: 'Contour' rhymes with 'tour' – imagine touring along a line of equal height.
等高线 – 地图上连接海拔相同点的棕色或橙色线条。密集表示陡坡，稀疏表示缓坡。谐音记忆：“contour”像“绕圈tour”，沿着等高线绕一圈。
Spot Height – A black dot on a map with a number giving the exact height in metres at that point. It is a precise measurement, not an interpolation.
点高程（标高） – 地图上黑点旁标注的确切海拔高度数。它是一个点上的精确测量值，而非估算。
Scale – The relationship between a distance on the map and the actual distance on the ground, e.g. 1:25,000 means 1 cm on the map equals 25,000 cm (250 m) in reality. Think 'scale model' – everything is reduced.
比例尺 – 图上距离与实际地面距离的比值，如 1:25,000 表示图上1厘米代表实地250米。联想“缩尺模型”，按比例缩小。
Four-Figure Grid Reference – A quick location method using the numbers of the grid lines, e.g. 1532. Always read 'along the corridor and up the stairs': eastings first (horizontal), then northings (vertical).
四位数网格坐标 – 用网格线编号快速定位的方法，如1532。口诀：“先横后纵，先读东距再读北距”，像走走廊再上楼。
Six-Figure Grid Reference – magine the square divided into 10 × 10 mini-lines; still eastings first, northings second.
六位数网格坐标 – 更精确的定位，把每个网格划分成十等份，如155 325。技巧：想象网格分为百格，仍遵循先东侧再北侧的顺序。
7. Fieldwork Essentials | 野外考察基础
Hypothesis – A testable statement or prediction that guides your fieldwork enquiry, e.g. 'Pedestrian counts are higher near the bus station.' Memory: Think 'hypothesis' = 'high-prediction' – an educated guess.
假设 – 指导野外调查的可检验陈述或预测，如“公交车站附近行人流量更大”。记忆法：假设就是先提出一个猜想，再去验证。
Primary Data – mation you collect yourself first-hand, such as traffic counts, surveys or field sketches. 'Primary' = first, just like primary school is your first school.
一手数据 – 亲自收集的第一手资料，例如交通计数、问卷或实地素描。记忆：“primary”就是最初的，像小学是第一个学校。
Secondary Data – Data gathered by someone else that you use, e.g. census statistics, maps, websites. 'Second'-ary means it is not your own first collection – someone else did it first.
二手数据 – 别人已经收集好的资料，比如人口普查数据、地图、网站信息。记忆：“second”意味着不是第一次收集，是别人做好的。
Sample – A small part of a larger population or area used to represent the whole, e.g. interviewing every 10th person. Trick: A food 'sample' gives you a taste of the whole dish; a field sample does the same for your study area.
样本 – 从较大的总体或区域中选出的用于代表整体的一小部分，比如每隔10人进行采访。联想：试吃“样品”让你尝到整盘菜的味道，样本同样提供整体信息。
Qualitative and Quantitative Data – and is often words; Quantitative measures quantities (numbers, measurements). Quick rhyme: 'Quality' = descriptive; 'Quantity' = countable.
定性数据与定量数据 – 定性描述属性（观点、颜色、感觉），多为文字；定量测量数量（数字、计量值）。口诀：定“质”是描述性质，定“量”是可数的。
8. Ecosystems and Biomes | 生态系统与生物群系
Biome – A large-scale ecosystem with a distinct climate, vegetation and animal life, such as tropical rainforest or tundra. Memory link: 'Bio' means life, '-ome' signals a large zone; together, a life-zone.
生物群系 – 具有特定气候、植被和动物的大尺度生态系统，例如热带雨林或冻原。词根记忆：“bio”生命，“-ome”大区域，合起来就是生命地带。
Adaptation – A characteristic that helps an organism survive in its environment, like a camel's hump for storing fat. Think: The plant or animal has 'adapted' its body or behaviour to fit its home.
适应 – 帮助生物在其环境中生存的特征，如骆驼的驼峰储存脂肪。联想：“adapt”就是调整自己以适应环境。
Food Chain – organism to another, starting with a producer (plant). Simple chain: Grass → Rabbit → Fox.
食物链 – 展示能量和养分从一种生物传递到另一种生物的序列，以生产者（植物）为起点。例子：青草→兔→狐狸。
Nutrient Cycle – The circulation of nutrients between living organisms, soil, and the atmosphere. In a forest, leaves fall, decay and return nutrients to the soil. Key idea: Nothing is wasted – it goes round and round.
