1. Atmospheric & Climatic Processes | 大气与气候过程
Atmospheric circulation is the global-scale movement of air that redistributes heat from the equator towards the poles. Picture three giant cells (Hadley, Ferrel, Polar) as conveyor belts driven by differential heating.
大气环流指空气在全球尺度的运动，将赤道热量向两极输送。想象三个巨型环流圈（哈得来、费雷尔、极地）就像由受热不均驱动的传送带。
The Coriolis effect is the apparent deflection of winds and ocean currents caused by Earth's rotation. Remember: 'In the Northern Hemisphere, objects curve to the RIGHT; in the Southern Hemisphere, to the LEFT.'
科里奥利效应是地球自转引起的风和洋流偏转现象。记住：‘北半球向右偏，南半球向左偏。’
The Intertropical Convergence Zone (ITCZ) is a low-pressure belt near the equator where trade winds meet, producing towering cumulonimbus clouds and heavy rainfall. Think of it as the thermal equator that migrates with the overhead sun.
热带辐合带（ITCZ）是赤道附近的低压带，信风在此汇聚，产生高耸的积雨云和强降雨。可将其视为随太阳直射点移动的热赤道。
Frontal rainfall occurs when a warm air mass meets a cold air mass; the less dense warm air is forced to rise, cools and condenses. A quick sketch of a cross-section with 'warm over cold' will lock this in.
锋面降雨发生在暖气团与冷气团相遇时，密度较小的暖空气被迫抬升、冷却凝结。画一个‘暖空气爬升冷空气’的剖面图就能轻松记住。
Albedo is the reflectivity of a surface, expressed as a fraction or percentage. Fresh snow has a high albedo (up to 0.9), whereas dark forest has a low albedo (around 0.1). Saying 'white reflects light' helps recall its effect on energy budgets.
反照率是地表的反射能力，用分数或百分比表示。新雪反照率高（可达0.9），而深色森林反照率低（约0.1）。记住‘白反射光’即可理解其对能量平衡的影响。
2. Hydrological Cycle & River Systems | 水文循环与河流系统
Infiltration is the downward movement of water from the surface into the soil. It is crucial for recharging groundwater; compacted or impermeable surfaces drastically reduce it, increasing surface runoff.
下渗指水从地表向下进入土壤的过程。它是地下水补给的关键；紧实或不透水的地面会极大地减少下渗，从而增加地表径流。
Throughflow is the lateral movement of water within the soil layer, guided by gravity and soil structure. Visualise water oozing slowly downhill between soil particles, eventually feeding into streams.
壤中流是水在土壤层内部受重力和土壤结构作用发生的侧向运动。想象水在土壤颗粒间缓慢向下坡渗流，最终汇入溪流。
he simple formula Q = A × V: discharge equals cross-sectional area multiplied by velocity.
流量是每秒通过河道的水体积，单位是立方米/秒（m³/s）。用简单公式 Q = A × V 记忆：流量等于过水断面面积乘以流速。
A storm hydrograph shows how a river's discharge responds to a rainfall event. The lag time — the delay between peak rainfall and peak discharge — reveals how quickly a catchment responds; short lag times spell flood risk.
暴雨过程线显示河流流量对降雨事件的响应。滞后时间——降雨峰值与流量峰值之间的延迟——反映流域响应速度；滞后时间短意味着洪涝风险高。
Abrasion (or corrasion) in rivers is the wearing away of the bed and banks by the load of sand and pebbles being dragged along. Remember it as 'sandpapering the channel'.
河流侵蚀中的磨蚀作用指河床和河岸被拖拽的砂石负载不断磨损。可记为‘砂纸打磨河道’。
3. Coastal Landforms & Processes | 海岸地貌与过程
Fetch is the uninterrupted distance over which wind blows across open water. The longer the fetch, the more energy waves accumulate, making them powerful agents of erosion. 'F' for fetch means 'F' for far – think of a far-reaching wind.
风区是风在开阔水面上吹拂的不受阻断的距离。风区越长，波浪积聚的能量越大，侵蚀力越强。用‘风区’的‘风’联想到‘远方之风’来记忆。
Swash is the forward surge of a wave up the beach, while backwash is the return flow down the beach. Constructive waves have a stronger swash that deposits material; destructive waves have a stronger backwash that erodes. Draw a simple arrow diagram to distinguish them.
冲流是波浪冲向海滩的上冲水流，回流则是退回的下降水流。建设性波浪冲流强而沉积物质；破坏性波浪回流强而侵蚀物质。画个箭头图即可分清。
Longshore drift is the zigzag transport of sediment along a coastline by waves striking the shore at an oblique angle. The swash pushes sand up at an angle, and gravity pulls the backwash straight down; the net result moves material along the coast like a conveyor belt.
沿岸漂沙是波浪以斜角冲击海岸时沉积物呈‘之’字形搬运的过程。冲流以一定角度将沙子推上去，重力使回流垂直退下；净效果使物质像传送带一样沿岸移动。
A stack is an isolated pinnacle of rock standing just offshore, formed when a headland is eroded into a cave, then an arch, and finally the arch roof collapses. Using a story: 'Cave-Arch-Stack-Stump' (CASS) helps sequence the landforms.
海蚀柱是矗立在近岸的孤立岩峰，由岬角先被侵蚀成洞、再成拱，最后拱顶崩塌而形成。用故事法‘洞-拱-柱-残根’（CASS）记住地貌顺序。
4. Glaciated Landscapes | 冰川景观
Ablation is the loss of ice and snow from a glacier through melting, sublimation or calving. It is the opposite of accumulation. Remember: 'A' for ablation is 'A' for away – the ice goes away.
消融是冰川通过融化、升华或崩解而流失冰雪的过程，与积累相反。记忆法：‘消融’的‘消’就是‘消失’。
Plucking occurs when meltwater seeps into cracks in bedrock, freezes, and then the glacier yanks out angular blocks of rock. Think of it as 'plucking teeth from the Earth'.
拔蚀作用是融水渗入基岩裂隙冻结，然后冰川将角状岩块拔出的过程。可形象地记为‘从大地上拔牙’。
A corrie (cirque) is an armchair-shaped hollow on a mountainside, formed by rotational ice erosion. Its steep back wall and over-deepened basin often hold a tarn after the ice melts. Trace the semicircular contour lines of a corrie on an OS map to embed the shape.
冰斗是山坡上由旋转冰流侵蚀而成的扶手椅状凹地。冰斗有陡峭的后壁和加深的斗底，冰川消退后常形成冰斗湖。在一幅地形图上描出冰斗的半圆形等高线就能牢记这一形态。
An arete is a knife-edged ridge between two corries, moulded by ice piling up against it from both sides. The word sounds like 'a-RET' — imagine a narrow ridge that would ret (tear) your shoes.
刃脊是两个冰斗之间的刀刃状山脊，两侧均受冰蚀塑造而成。发音联想‘刃脊’的‘刃’，像一把薄刃的刀，走在上面会割破鞋子。
Drumlins are streamlined, egg-shaped hills of glacial till, with the blunt end pointing up-valley. They often appear in swarms, giving a 'basket of eggs' topography. The steeper stoss end faces the ice advance direction.
鼓丘是由冰碛物构成的流线型蛋状小丘，钝端指向谷的上游。它们常成群出现，形成‘一篮鸡蛋’的地貌。较陡的迎冰坡朝向冰川前进方向。
5. Population Change & Migration | 人口变化与迁移
Crude Birth Rate (CBR) is the number of live births per 1,000 population per year. It is 'crude' because it doesn't account for age or sex structure. Just remember: births ÷ total people × 1000.
粗出生率（CBR）是每千人口年活产婴儿数。之所以称‘粗’，是因为它未考虑年龄和性别结构。只需记：出生数 ÷ 总人口 × 1000。
The Demographic Transition Model (DTM) tracks a country's population shift from high birth and death rates to low ones through five stages. Visualise it as a double curve with birth and death rates, and a gap showing natural increase. 'B-D-N' – Birth, Death, Natural increase.
人口转变模型（DTM）通过五个阶段描绘一个国家从高出生率、高死亡率向低出生率、低死亡率的转变。把它想象成出生率和死亡率的双曲线，两条线的间隙表示自然增长。记住‘生-死-增’即可。
ratio means heavy pressure on state resources. Formula: (young + old) ÷ working age × 100.
抚养比指被抚养人口（0-14岁及65岁以上）与劳动年龄人口（15-64岁）的比例。高抚养比意味着国家资源压力大。公式：（幼+老）÷ 劳动年龄人口 × 100。
rs are positives that attract them (e.g., job opportunities, safety, better services). Use 'push = pain, pull = promise' as a mantra.
推力因素是推动人们离开某地的负面条件（如失业、饥荒、冲突）。拉力因素是吸引他们的积极因素（如就业机会、安全、优质服务）。用‘推=痛苦，拉=希望’来记忆。
6. Urban Geography & Settlements | 城市地理与聚落
The Central Business District (CBD) is the commercial and often historic heart of a city, characterised by tall buildings, high land values and peak accessibility. Look for the junction of major transport routes and a clock tower — classic CBD signatures on a map.
中央商务区（CBD）是城市商业和历史文化核心，特点是高楼林立、地价高昂和交通最便捷。在地图上找到主干交通交汇处和钟楼，就是CBD的典型标志。
ire for more space. Remember the sequence: CBD → inner city → inner suburb → outer suburb.
郊区化指居住区从内城向外围郊区扩展的过程，由交通改善和对更大居住空间的追求驱动。记住顺序：CBD → 内城 → 近郊区 → 远郊区。
Counter-urbanisation is the movement of people and employment from major cities to smaller towns or rural areas. It is the reverse of urbanisation, often linked to remote working and a search for quality of life. Think 'counter' as 'against the city'.
逆城市化是人口和就业从大城市向小城镇或农村迁移的过程。它是城市化的逆转，通常与远程办公和对生活品质的追求相关。把‘逆’理解为‘反城市’。
Gentrification is the renovation of deteriorated urban neighbourhoods by more affluent newcomers, leading to rising property values and the displacement of longer-term, lower-income residents. 'Gentr-' hints at 'gentry', suggesting a class shift in the area.
绅士化指较富裕的新居民对衰败城区的翻新改造，导致房价上涨和原有低收入居民被迫迁出。‘绅士’二字揭示了该地区阶层的变化。
7. Rural Land Use & Change | 农村土地利用与变化
Diversification on a farm means branching out from traditional agriculture into new income sources, such as farm shops, holiday lets or wind turbines. It is a common response to falling profit margins. Think 'farm + business' to capture the idea.
农场多元化经营指从传统农业拓展到新的收入来源，如农场商店、假日出租或风力发电。这是应对利润率下降的常见做法。用‘农场+生意’来理解。
The Common Agricultural Policy (CAP) was the EU' to rural development and environmental stewardship. Remember it as a three-stage journey: 'grow food → care for land → climate action'.
共同农业政策（CAP）是欧盟对农民的补贴与支持体系，已从价格支持发展为促进农村发展和环境管理。记住它的三阶段历程：‘生产粮食 → 管护土地 → 气候行动’。
Rural depopulation is the long-term decline of population in countryside areas, driven by out-migration of young people and farm mechanisation. It often leads to service closures and an ageing population profile. The 'depop' sound mirrors 'de-pop' — the people are leaving.
农村人口减少指农村地区长期的人口下降，由青年人外迁和农业机械化引起。它常导致服务设施关闭和人口老龄化。‘减少’二字就是‘减人去’。
The rural-urban fringe is the boundary zone where city meets countryside, marked by a mix of land uses such as golf courses, retail parks and nature reserves. It is under pressure from urban sprawl. On a land-use map it looks like a patchwork quilt.
城乡交错带是城市与乡村交汇的边界地带，土地混合利用，常见高尔夫球场、购物公园和自然保护区。它承受城市蔓延的压力。在土地利用图上看起来像一块拼布被面。
8. Development & Health | 发展与健康
Gross Domestic Product (GDP) is the total value of all goods and services produced within a country in a year. GDP per capita divides this by population, giving a rough measure of average income. Remember: 'D' for domestic – within the country's borders.
国内生产总值（GDP）是一国一年内所有商品与服务的总价值。人均GDP除以人口，是居民平均收入的粗略衡量。记‘内’字——在一国境内。
The Human Development Index (HDI) combines life expectancy, education (mean years of schooling) and GNI per capita into a single score between 0 and 1. It provides a more rounded development picture than GDP alone. The three components spell 'L-E-I' — Length of life, Education, Income.
人类发展指数（HDI）将预期寿命、教育（平均受教育年限）和人均国民总收入综合成一个0到1的评分，比单独的GDP更全面。三部分合起来是‘寿-教-收’。
Fair trade is a trading partnership that seeks greater equity in international trade by paying producers a fair price and offering better working conditions. It offers an alternative to the exploitation of primary producers. Look for the Fairtrade logo on products as a reminder.
公平贸易是一种贸易伙伴关系，通过支付生产者公平价格和提供更好的工作条件来促进国际贸易的公平性。它是对初级生产者被剥削的替代方案。看到产品上的公平贸易标志就能想起。
The North-South divide describes the socio-economic gap between the wealthier, industrialised 'Global North' and the poorer, developing 'Global South'. While simplistic, it remains a useful shorthand for global inequality. Visualise a world map with a wavy line around 30°N.
南北差异描述富裕工业化‘全球北方’和贫穷发展中‘全球南方’之间的社会经济差距。虽然简单化，但它仍是概括全球不平等的有效方式。可想象世界地图上约北纬30°的一条波浪线。
9. Geographical Information Systems (GIS) | 地理信息系统
A layer in GIS is a digital dataset representing a theme, such as roads, rivers or land use. Layers can be stacked and analysed to reveal spatial relationships. Think of a sandwich: each layer is a slice that together builds the full picture.
图层是GIS中代表一个主题（如道路、河流或土地利用）的数字数据集。图层可叠置分析以揭示空间关系。想象一个三明治：每一层都是完整图像的一个切片。
Raster data consists of a grid of cells (pixels), each holding a value — gery. Vector data uses points, lines and polygons to represent discrete features. Remember 'raster = regular grid, vector = versatile shapes'.
栅格数据由像元网格构成，每个像元存有一个值，适用于高程、卫星影像等连续数据。矢量数据用点、线、多边形表示离散地物。记住‘栅=格，矢=形’。
Attribute data is the descriptive information linked to a spatial feature, such as the name of a river or the population of a county. Without attributes, a map is just lines and colours. The table behind the map is as important as the map itself.
属性数据是关联到空间地物的描述性信息，比如河流名称或县的人口。没有属性，地图只是线条和颜色。地图背后的表格与地图本身同等重要。
Spatial analysis encompasses techniques like buffering, overlay and network analysis to extract new information from geographic data. To memorise, think 'S-P-A': Search for patterns, Proximity queries, and Areas of intersection.
空间分析包括缓冲区、叠置、网络分析等技术，从地理数据中提取新信息。可用‘空-近-叠’三字诀：空间模式、近邻查询、叠置区域。
10. Map & Graphical Skills | 地图与图表技能
A contour line joins points of equal height above sea level. The closer the contours, the steeper the slope. When asked to describe relief, always comment on spacing, pattern and shape.
等高线连接海拔高度相同的各点。等高线越密集，坡度越陡。描述地形时，务必评价等高线的疏密、形态和组合形状。
A four-figure grid reference (e.g., 2345) locates a 1 km² grid square; easting first, northing second. A six-figure grid reference (e.g., 236451) pinpoints a specific point. The rhyme 'along the corridor and up the stairs' reminds you to go eastings then northings.
四位网格坐标（如2345）定位一个1平方公里的网格方格，先读东距再读北距。六位网格坐标（如236451）精确定位一个点。口诀‘先走走廊再上楼梯’提醒你先东后北。
A scatter graph shows the relationship between two variables. If points cluster along a diagonal, the correlation is strong; a positive slope indicates a positive correlation. Never plot the dots before labelling your axes!
散点图显示两个变量间的关系。若点沿对角线聚集，则相关性强；斜率为正表示正相关。务必先标注坐标轴再描点！
A triangular graph displays three components that sum to 100%, such as soil texture or employment structure. Read it by following the axis lines parallel to the sides. Remember, each vertex represents 100% of one component.
三角坐标图显示三个合计为100%的成分，如土壤质地或就业结构。读取时要沿着平行于三角形各边的轴线进行。记住，每个顶点代表该成分的100%。
11. Fieldwork & Research Methods | 实地考察与研究方法
dence. Secondary data comes from existing sources like census reports or online databases. 'Primary = project you' can be a memory prompt.
一手数据是你自己通过测量、问卷或观察收集的信息，是专门为研究目的获取的原始证据。二手数据来自已有资料，如人口普查报告或在线数据库。用‘一手亲为’来记。
Random sampling gives every member of a population an equal chance of being chosen, eliminating selection bias. Systematic sampling selects subjects at regular intervals (e.g., every 10th house). Stratified sampling divides the area into subgroups and samples proportionally. For the exam, remember 'R-S-S' and when to use each.
随机抽样使总体中每个个体都有同等被选中的机会，消除了选择偏差。系统抽样按固定间隔选取样本（如每10栋房屋）。分层抽香先将区域分层，再按比例抽样。考试时记住‘随-系-层’及各自适用场景。
A hypothesis is a clear, testable statement predicting a relationship or difference, such as 'Channel depth increases with distance downstream.' It must include a measurable outcome. The null hypothesis always states there is no effect.
假设是一个清晰、可检验的陈述，预测某个关系或差异，如‘河道深度随下游距离增加而增大’。它必须包含可测量的结果。零假设则总是声称没有效应。
Ethical considerations in fieldwork involve respecting participants' privacy, obtaining consent, minimising environmental impact and ensuring safety. Before any data collection, complete a risk assessment and an ethical checklist.
实地考察的伦理考量包括尊重参与者隐私、获取同意、减少环境影响并确保安全。在任何数据采集之前，要完成风险评估和伦理清单。
12. Environmental Challenges | 环境挑战
cause. Adaptation involves adjusting to the impacts already underway, such as building sea walls or developing drought-resistant crops. 'Mitigation = minimise the menace; adaptation = accommodate the aftermath' is a useful mnemonic.
气候变化减缓旨在通过可再生能源、碳捕获或能效提升来减少温室气体排放，直击原因。适应则是针对已发生的影响进行调整，如修建海堤或培育抗旱作物。‘减缓减根源，适应面对后果’是个好记的顺口溜。
A carbon footprint is the total amount of greenhouse gases produced directly and indirectly by an individual, event or product, expressed in tonnes of CO₂ equivalent. Everything from food miles to home heating counts. Seeing your own footprint quantified can be a shock.
碳足迹是一个个人、活动或产品直接和间接产生的温室气体总量，以吨二氧化碳当量表示。从食物里程到家庭供暖统统包括在内。看到自己的足迹数值会让人心头一震。
Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas, caused by factors like overgrazing, deforestation and climate variation. It does not mean the desert advances like a wave; rather, productive land becomes desert-like. Use 'D-E-S-E-R-T: Deforestation, Overgrazing, Soil erosion, Excessive irrigation, Climate change' as a causation checklist.
荒漠化是干旱、半干旱及干燥半湿润地区的土地退化，由过度放牧、森林砍伐和气候变化等因素引起。它并非沙漠如潮水般推进，而是丰产土地变成沙漠状。用‘荒-牧-土-水-气’：荒漠化因素有过度放牧、毁林、水土流失、不合理灌溉和气候变化。
Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs. The classic Venn diagram of environment, society and economy captures the concept. Think of the three-legged stool: remove one leg and sustainability collapses.
可持续发展是满足当代需求又不损害后代满足其需求的能力。经典的环境、社会和经济三环维恩图抓住了这一概念。把它想成一条三脚凳：抽掉任何一条腿，可持续性就会倒塌。
