1. River Processes | 河流作用术语
Erosion in rivers happens in four main ways. Hydraulic action is the sheer force of water breaking rock particles away from the bed and banks. Abrasion (corrasion) is the scraping effect of the river's load—like sandpaper wearing away the channel.
河流的侵蚀作用主要有四种。水力作用指水流冲击的力量把岩石颗粒从河床和河岸剥离下来。磨蚀作用就像砂纸，是河流携带的沙石不断刮擦河道的效果。
Attrition is the collision and grinding of rocks carried by the river; they become smaller, smoother, and more rounded over time. Solution (corrosion) is the chemical dissolving of soluble minerals such as limestone in slightly acidic water.
磨圆作用是指河水中携带的石块相互碰撞、磨碎，随时间推移越来越小、越光滑、越圆。溶蚀作用则是弱酸性河水化学溶解石灰岩等可溶矿物的过程。
Once material is eroded, the river transports it. Traction is the rolling of large boulders along the river bed. Saltation is the bouncing movement of smaller stones. Suspension carries fine particles like silt within the water column. Dissolved load moves invisibly in solution. When the river loses energy, deposition occurs—dropping its load, often on the inside of meanders or at a river mouth.
侵蚀下来的物质需要搬运。推移是指大砾石在河床上滚动；跃移是小石子跳跃前进；悬移是细小的泥沙悬浮在水中；溶解质则看不见地随水流动。当河流能量下降，就会发生沉积，常在曲流的内弯或河口卸下负载。
Memory tip: Link 'hydraulic' to hydraulic pressure in machines; 'abrasion' to abrasive pads; 'attrition' to the word 'attrite' (wear down); 'solution' to dissolving sugar in tea.
记忆窍门：'hydraulic' 联想液压机械的力量；'abrasion' 联想研磨用的砂纸；'attrition' 联想 'attrite'（磨损）一词；'solution' 像糖溶在茶里。
2. Coastal Landforms | 海岸地貌词汇
Waves constantly shape coastlines. Constructive waves have a strong swash and weak backwash, building up beaches. Destructive waves are the opposite—strong backwash erodes the coast. The fetch is the distance of open water over which the wind blows, affecting wave energy.
海浪不断塑造着海岸线。建设性海浪的冲流强、回流弱，会把沙子带上岸堆积成海滩。破坏性海浪正好相反，回流强，侵蚀海岸。风区长度是风吹过开阔水面的距离，它决定了海浪的能量大小。
Erosion along coasts produces distinct landforms. A cliff is a steep rock face formed by undercutting from hydraulic action and abrasion. A wave-cut notch is an indent at the base of a cliff. When the notch collapses, the cliff retreats, leaving a wave-cut platform—a flat rocky area visible at low tide.
海岸侵蚀形成独特的地貌。悬崖是水力作用和磨蚀掏空底部形成的陡峭岩壁。浪蚀凹陷是悬崖脚部的凹槽。凹槽坍塌后悬崖后退，留下浪蚀平台——一个在低潮时可见的平坦岩石面。
Headlands and bays develop where alternating bands of hard and soft rock meet the sea. The soft rock (e.g., clay) erodes faster forming a bay, while the hard rock (e.g., chalk) sticks out as a headland. Further erosion can create caves, arches, stacks, and stumps.
当软硬相间的岩层与海水相遇，就会形成岬角和海湾。软岩（如黏土）侵蚀快，形成海湾；硬岩（如白垩）突出来成为岬角。进一步侵蚀可形成海蚀洞、海蚀拱、海蚀柱和海蚀残丘。
Fast recall: Imagine a cliff as a giant wall. Wave-cut notch is like a shoe scuffing against the wall's base. Headlands are the 'hard heads' that resist the sea; bays are the 'soft bellies' that yield.
快速回忆：把悬崖想象成一道大墙。浪蚀凹陷就像鞋子反复踢墙脚留下的痕迹。岬角是 'hard heads'（硬脑袋）抵抗海水；海湾是 'soft bellies'（软肚皮）退缩形成的。
3. Weather and Climate | 天气与气候
Weather is the day-to-day state of the atmosphere—temperature, precipitation, wind, and humidity. Climate is the long-term average weather pattern in an area, usually measured over 30 years. Knowing the difference is fundamental: 'weather is your mood, climate is your personality.'
天气是指大气的日常状态，包括温度、降水、风和湿度。气候是一个地区长期的天气平均模式，通常统计30年。了解两者的区别很关键：'天气是你的心情，气候是你的性格。'
Several instruments measure these elements. A thermometer records temperature in degrees Celsius (°C) or Fahrenheit (°F). A rain gauge catches precipitation; its measurement is in millimetres. A barometer detects air pressure—rising pressure suggests settled weather, falling pressure hints at storms. An anemometer spins to measure wind speed, while a wind vane points to wind direction.
测量这些要素的仪器有多种。温度计以摄氏度或华氏度记录气温。雨量计承接降水，以毫米为单位。气压计探测气压，气压上升预示天气稳定，下降预示风暴。风速计旋转测量风速，风向标则指示风向。
Climate graphs combine a line graph of temperature with a bar chart of precipitation for each month. They help you quickly see wet/dry seasons and temperature ranges. The annual range is the difference between the hottest and coldest month.
气候图表把温度的年变化曲线和降水量的月柱状图结合起来，让你一眼可看出干湿季和温度变幅。年较差就是最热月和最冷月的气温差。
Memory hook: 'Thermometer' has 'therm' meaning heat; 'barometer' has 'baros' meaning weight (air pressure). For rain gauge, think 'gauge' = measure; it 'gauges' rainfall.
记忆钩子：'Thermometer' 中有 'therm' 表示热；'barometer' 中有 'baros' 表示重量（气压）。'Rain gauge' 里的 'gauge' 就是测量，'量'雨的工具。
4. Population and Settlement | 人口与聚落
Population distribution describes where people live—sparse (few people) or dense (many people). Population density is the number of people per square kilometre (e.g., people/km²). Dense population in fertile river valleys, sparse in deserts or high mountains.
人口分布描述人们住在哪里——稀疏（人少）或稠密（人多）。人口密度指每平方千米的人数（如人/平方公里）。肥沃的河谷人口稠密，沙漠和高山人口稀疏。
Settlements can be classified by their function and size. A hamlet is a tiny settlement with a few houses; a village has more services like a shop or school; a town has a wider range; a city is larger, often with a cathedral, major shopping centres, and administrative functions. The site of a settlement is the actual land it is built on; its situation is the location in relation to surrounding features.
聚落可以按功能和规模划分。小村（hamlet）只有几户人家；村庄（village）有商店或学校等基本服务；镇（town）服务更广；城市（city）更大，通常有大教堂、大型商业和行政功能。聚落的site（地点）指其实际占据的土地；situation（区位）指其与周围地物的关系。
Internal land use in urban areas is explained by urban models. The Central Business District (CBD) is the commercial heart, with high land values and tall buildings. Residential areas vary from inner-city terraces to suburban semi-detached houses. An important process is urbanisation—the increase in the proportion of people living in towns and cities in a country.
城市内部土地利用可以用城市模型解释。中心商业区（CBD）是商业心脏，地价高、高楼林立。居住区从内城的排屋到郊区半独立屋不等。一个重要过程是城市化——即一国城镇人口比例的增加。
Study trick: For 'site' vs 'situation', remember: Site is the exact spot (think 'sitting on a site'); situation describes what is near (situation = sit in relation to nearby things).
学习技巧：区分 'site' 和 'situation'：Site 是具体的落点（你'坐'在那个点）；situation 描述周围有什么（sit+u+ation = 你的位置与周围物的关系）。
5. Economic Activities | 经济活动
Economic activities are categorised into sectors. Primary industries extract raw materials: farming, fishing, mining, forestry. Secondary industries manufacture goods from raw materials: car assembly, textile production, food processing. Tertiary industries provide services: teaching, retail, healthcare, tourism. Quaternary industries involve information and research, like software development and scientific R&D.
经济活动分为不同产业部门。第一级产业（初级产业）直接开采自然资源：农业、渔业、采矿、林业。第二级产业（制造业）将原材料加工成产品：汽车装配、纺织、食品加工。第三级产业（服务业）提供各种服务：教学、零售、医疗、旅游。第四级产业涉及信息与研究，如软件开发和科学研发。
Globalisation refers to the increasing connections between countries through trade, investment, and communication. Multinational corporations (MNCs) operate in several countries, like a sportswear company designing in the US, manufacturing in Vietnam, and selling worldwide. Employment structure is the proportion of people working in each sector; it changes as a country develops—from primary dominance to tertiary dominance.
全球化指通过贸易、投资和通讯使各国之间的联系日益加深。跨国公司（MNCs）在多个国家运营，比如一家运动服装公司在美国设计、在越南制造、全球销售。就业结构是指各产业部门从业人员比例；随着国家发展，从第一产业为主转变为第三产业为主。
Visual memory: Picture a pyramid—base is primary (needed for everything), middle is secondary (making things), top is tertiary and quaternary (services and ideas). An MNC can be imagined as an octopus with tentacles in many countries.
图像记忆：画一个金字塔——底部是初级产业（一切的基础），中部是制造业（制造产品），顶部是服务业和第四产业（服务与创意）。跨国公司则可想象为一只章鱼，触手伸向多国。
6. Tectonic Hazards | 构造灾害
The Earth's crust is broken into tectonic plates that float on the semi-molten mantle. Convection currents in the mantle drive plate movement. At plate boundaries, three main types of interaction occur: convergent (plates move towards each other), divergent (plates move apart), and transform (plates slide past each other).
地壳分裂成多个构造板块，漂浮在半熔的地幔之上。地幔中的热对流驱动板块运动。在板块交界处，有三种主要相互作用：汇聚（板块相向而行）、离散（板块相背而行）和转换（板块侧向滑过）。
Earthquakes result from sudden release of built-up pressure along faults, often at transform boundaries. The point inside the Earth where the quake starts is the focus; directly above on the surface is the epicentre. Seismic waves radiate out; the Richter scale measures magnitude (amount of energy). A volcano is an opening where magma, ash, and gases escape; it can form at convergent (subduction) and divergent boundaries.
地震是断层处积累的压力突然释放的结果，常发生在转换边界。地震起始点在地球内部叫震源；正上方的地面点叫震中。地震波向外扩散；里氏震级衡量震级（能量大小）。火山是岩浆、火山灰和气体喷出的通道，可在汇聚（俯冲）和离散边界形成。
People can prepare for tectonic hazards. Monitoring equipment detects tremors; hazard maps show risk zones; evacuation plans save lives. In wealthy countries, earthquake-resistant buildings with deep foundations and shock absorbers reduce damage.
人们可以为构造灾害做准备。监测仪器可探测微震；灾害地图标出风险区；疏散计划能拯救生命。在富裕国家，有深地基和减震装置的抗震建筑可减轻破坏。
Recall cue: Think of plates as a cracked eggshell. Focus = 'focal point' inside the egg. Epicentre = 'epi' + centre, the point upon the surface. Volcano = imagine a pressure cooker releasing steam.
记忆提示：把板块想象成破碎的蛋壳。Focus（震源）= 蛋内的'焦点'。Epicentre（震中）= 'epi'（在...上）+ centre，地表上的中心。Volcano（火山）= 就像高压锅释放蒸汽。
7. Map Skills | 地图技能
Maps are geographers' essential tools. A grid reference pinpoints location: four-figure references (e.g., 4723) locate a 1 km square; six-figure references (472233) locate a 100 m square. Remember: 'along the corridor, then up the stairs'—easting first (horizontal), northing second (vertical).
地图是地理学家的基本工具。网格坐标可以精确定位：四位数坐标（如4723）定位1公里方格；六位数坐标（472233）定位100米方格。记住：'先走走廊，再上楼梯'——先读东向值（水平），后读北向值（垂直）。
Scale expresses the ratio between map distance and real distance. A scale of 1:25 000 means 1 cm on the map equals 25 000 cm (250 m) on the ground. Contour lines connect points of equal height; they show relief. Close contours indicate a steep slope; wider spacing means a gentle slope. Spot heights are exact heights marked with a dot.
比例尺表示图上距离与实地距离的比值。1:25 000 表示图上1厘米等于实地25000厘米（250米）。等高线连接相同高度的点，显示地形。密等高线表示陡坡；宽间距表示缓坡。高程点是用圆点标出的精确高度。
Physical features like rivers, forests, and cliffs use symbols. Human features include roads, settlements, and boundaries. The map key (legend) unlocks all these symbols. Relief shading can also indicate steepness.
河流、森林、悬崖等自然地物使用符号表示。人文地物包括道路、聚落和界线。图例解释所有符号。晕渲法也可以表示坡度。
Never forget: Eastings go eastward (across), Northings go northward (up). Scale 1:50 000 is bigger than 1:250 000—less reduction means more detail. Contour lines never cross each other.
永不忘记：东向值沿东方向（横向），北向值沿北方向（纵向）。比例尺1:50 000比1:250 000更大——缩小倍数越小，细节越多。等高线永不相交。
8. Environmental Issues | 环境问题
Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs. It balances three pillars: economic, social, and environmental. The term carbon footprint refers to the total greenhouse gas emissions caused directly and indirectly by an individual, organisation, or product.
可持续发展既满足当代需求，又不损害后代满足其需求的能力。它平衡三大支柱：经济、社会和环境。碳足迹是指个人、组织或产品直接和间接产生的温室气体排放总量。
Climate change results from increased greenhouse gases like carbon dioxide (CO₂) and methane (CH₄). Enhanced greenhouse effect traps extra heat. Consequences include global warming, rising sea levels, more extreme weather events, and melting ice caps. Mitigation involves reducing emissions; adaptation involves adjusting to changes already happening.
气候变化由二氧化碳（CO₂）和甲烷（CH₄）等温室气体增加造成。增强的温室效应困住更多热量。后果包括全球变暖、海平面上升、极端天气事件增多和冰盖融化。减缓指减少排放；适应指调整应对已发生的变化。
Ecosystems are communities of living organisms interacting with their non-living environment. Deforestation—large-scale removal of trees—destroys habitats, reduces biodiversity, and releases stored carbon. Biodiversity is the variety of life in a habitat; a high biodiversity makes an ecosystem more resilient.
生态系统是生物群落与其非生物环境相互作用的整体。森林砍伐——大规模清除树木——会破坏栖息地、降低生物多样性并释放储存的碳。生物多样性是指生境中生命的多样性；高生物多样性使生态系统更有韧性。
Memory link: 'Sustainable' the mark you leave on the planet through carbon, like a footprint in sand. Biodiversity = 'bio' (life) + diversity (variety).
记忆链接：'Sustainable' = sustain（维持）+ able（能够）= 能长期维持的。Carbon footprint = 你通过碳在地球上留下的印记，就像沙滩上的脚印。Biodiversity = 'bio'（生命）+ diversity（多样性）。
9. Urbanisation | 城市化关键词
Urbanisation is the growth in the proportion of a country's population living in urban areas. It occurs because of rural-to-urban migration (push factors like lack of jobs in countryside, pull factors like better education in cities) and natural increase (higher birth rates in urban areas).
城市化是指一国城市人口比例不断增长。因为乡村到城市的迁移（推因素如农村就业机会少，拉因素如城市教育更好）和自然增长（城市地区较高的出生率）而发生。
A megacity is a city with a population of over 10 million people. Many megacities are in developing nations, e.g., Mumbai, Lagos. Urban sprawl is the uncontrolled expansion of urban areas into surrounding rural land, often resulting in low-density housing and long commutes.
特大城市指人口超过1000万的城市，许多位于发展中国家，如孟买、拉各斯。城市蔓延是城区不受控制地向周围乡村土地扩张，往往形成低密度住宅和长距离通勤。
Counter-urbanisation is the process of people moving from urban areas to rural areas—opposite to urbanisation. It often involves wealthier people seeking better quality of life. Re-urbanisation occurs when city centres are regenerated, attracting people back. Urban regeneration projects improve derelict areas with new homes, services, and green spaces.
逆城市化是人们从城市迁往乡村的过程——与城市化相反，常是有钱人追求更高生活质量。再城市化是指市中心经过重建吸引人口回流。城市更新项目通过新住房、服务和绿地改善旧区。
Quick distinction: es. Re-urbanisation = people return to regenerated cities. Megacity = mega (million x 10).
快速区分：Urbanisation = 城市人变多。Counter-urbanisation = 人离开城市。Re-urbanisation = 人回到更新后的城市。Megacity = mega（百万 x 10）。
