1. River Landscapes | 河流地貌
Source: The starting point of a river, usually in upland areas with high rainfall, often marked by a spring or boggy ground.
源头：河流的起点，通常位于降水充沛的高地，常以泉水或沼泽地标出。
Mouth: The point where a river flows into a larger body of water, such as a sea or lake; deposition often creates deltas or estuaries.
河口：河流流入更大水体（如海洋或湖泊）的地方，沉积作用常形成三角洲或河口湾。
Drainage basin: An area of land drained by a river and its tributaries, bounded by a watershed.
流域：由一条河流及其支流排水的地表区域，其边界为分水岭。
Hydraulic action: A river erosion process where the force of moving water breaks loose and removes material from the bed and banks.
水力作用：河流侵蚀过程，水流的冲力使河床和河岸的物质松动并被移走。
Meander: A large, sweeping curve in the middle or lower course of a river, formed by lateral erosion and deposition.
曲流（河曲）：河流中下游出现的大型蜿蜒弯曲段，由侧向侵蚀与沉积共同形成。
Oxbow lake: A crescent-shaped lake formed when a meander is cut off from the main river channel through deposition and neck cut-off.
牛轭湖：当曲流颈部被切断，废弃河道与主流分离后形成的月牙形湖泊。
2. Coastal Landscapes | 海岸地貌
Longshore drift: The movement of sand and pebbles along a beach caused by waves approaching the shore at an angle, resulting in a zigzag movement of material.
沿岸漂移：波浪以斜角冲击海滩，造成沙石沿海岸作锯齿状移动的过程。
Headland and bay: A coastline configuration where resistant rocks form headlands that protrude into the sea, while softer rocks erode to form bays.
岬角与海湾：抗蚀能力强的岩石形成突入海中的岬角，软岩被侵蚀后退形成海湾。
Wave-cut platform: A gently sloping, rocky surface found at the base of a retreating cliff, exposed at low tide after prolonged erosion.
波切台：位于后退悬崖基部的一个平缓岩质平台，长期侵蚀后在低潮时出露。
Stack: An isolated pillar of rock separated from a headland due to the collapse of an arch, formed by coastal erosion.
海蚀柱：由于拱门坍塌而从岬角分离的孤立岩柱，由海岸侵蚀作用形成。
Spit: A long, narrow accumulation of sand or shingle extending out from the coast into the sea, often curved at the end due to wave refraction.
沙嘴：由沙或卵石组成的长条形沉积体，从海岸伸入海中，末端常因波浪折射而弯曲。
3. Weather and Climate | 天气与气候
Convectional rainfall: Precipitation caused by the heating of the ground, which warms the air above, causing it to rise rapidly, cool, and condense.
对流雨：由于地面受热，上方空气升温迅速上升、冷却凝结而形成的降水。
Relief rainfall: Precipitation that occurs when moist air is forced to rise over a mountain barrier, cools adiabatically and condenses into clouds.
地形雨：湿润空气被地形障碍（如山脉）抬升，绝热冷却凝结而产生的降水。
Anticyclone: A large-scale system of high atmospheric pressure with descending air, leading to clear skies and calm, settled weather.
反气旋：大范围高压系统，空气下沉，带来晴朗、稳定的天气。
Depression: A low-pressure weather system where air rises, leading to cloud formation, precipitation, and often strong winds.
气旋（低压系统）：低压天气系统，空气上升，导致云层形成、降水，通常伴有强风。
Greenhouse effect: The process by which gases in the atmosphere, such as carbon dioxide, trap heat from the sun, warming the Earth's surface.
温室效应：大气中的二氧化碳等气体吸收太阳热量，使地球表面变暖的过程。
4. Ecosystems and Biomes | 生态系统与生物群落
Ecosystem: A community of living organisms interacting with each other and their non-living environment, such as a pond or woodland.
生态系统：生物群落与其非生物环境相互作用构成的统一整体，如池塘或林地。
Biome: A large-scale global ecosystem characterised by distinct climate, vegetation, and animal life, such as tropical rainforest or tundra.
生物群落（生物群系）：全球尺度的大生态系统，具有特定气候、植被和动物群，如热带雨林或苔原。
Food web: A network of interconnected food chains within an ecosystem, showing how energy and nutrients flow through different organisms.
食物网：生态系统中多个食物链相互交织而成的网络，展示能量和营养如何在各种生物间流动。
Nutrient cycle: The movement and recycling of nutrients between living organisms, dead organic matter, and the soil within an ecosystem.
养分循环：生态系统中营养元素在生物、死有机质和土壤之间的迁移与再循环过程。
Tropical rainforest: A biome found near the Equator with high temperatures, heavy rainfall, and dense, evergreen vegetation with high biodiversity.
热带雨林：分布于赤道附近的生物群落，高温多雨，常绿阔叶植被茂密，生物多样性极高。
5. Population and Migration | 人口与迁移
Population density: The number of people living per unit area, usually expressed as persons per square kilometre.
人口密度：单位面积上居住的人口数，通常表示为每平方公里人数。
Natural increase: The difference between the birth rate and the death rate in a population, excluding migration.
自然增长率：人口出生率与死亡率之差，迁移不计入内。
Push factors: Negative conditions in a person's origin area that encourage them to leave, such as war, unemployment, or natural disasters.
推力因素：原居住地促使人们离开的负面因素，如战争、失业或自然灾害。
Pull factors: Positive attributes of a destination that attract migrants, such as better job opportunities, safety, or higher living standards.
拉力因素：目的地吸引移民的积极特征，如更好的就业机会、安全或更高的生活水平。
Population pyramid: A bar chart showing the age and sex structure of a population, with males on the left and females on the right.
人口金字塔：显示人口年龄和性别结构的条形图，左侧为男性，右侧为女性。
6. Settlement and Urbanisation | 定居点与城市化
Site: The actual physical location of a settlement, including its relief, water supply, and soil characteristics.
选址（地点）：聚落所在的实际自然地理位置，包括地势、水源和土壤等特征。
Situation: The location of a settlement relative to its surrounding area and other places, such as its proximity to resources or transport links.
