1. Systems and Feedbacks | 系统与反馈
Understanding systems is foundational in both physical and human geography. Below are key terms related to system types and the feedback loops that maintain or disrupt equilibrium.
理解系统是自然地理和人文地理的基础。以下是系统类型以及维持或打破平衡的反馈循环的关键术语。
Open system: A system that exchanges both energy and matter with its surroundings. Example: a drainage basin receives water and solar energy. Memory tip: ‘Open = Both – think of an open window letting in air and light.’
开放系统： 与外界交换能量和物质的系统。例如流域接收水和太阳能。记忆诀窍：’开放=两者 一 想想开窗通风和采光。’
Closed system: Transfers energy but not matter across its boundary. The global water cycle is effectively a closed system because total water is fixed. Mnemonic: ‘Closed = Energy only, no mass escape – like a sealed water bottle.’
封闭系统： 边界处只传递能量而不传递物质。全球水循环实质上是封闭系统，因为总水量固定。记忆：’封闭=仅能量 一 像密封水杯，水出不去。’
Dynamic equilibrium: A state of balance maintained by constant adjustments through feedback. A beach profile can remain stable if erosion equals deposition. Visual cue: scales constantly moving but overall balanced.
动态平衡： 通过反馈不断调节而维持的平衡状态。例如海滩侵蚀与堆积相等时剖面稳定。视觉提示：天平微微晃动但整体平衡。
Positive feedback: An initial change amplifies itself, moving the system away from equilibrium. Melting ice → lower albedo → more absorption → further melting. Remember ‘snowball effect’ – runaway loop.
正反馈： 初始变化自我放大，使系统偏离平衡。融冰 → 反照率降低 → 吸收更多辐射 → 进一步融化。记住’雪球效应’ 一 失控循环。
Negative feedback: Counteracts change, pushing the system back towards equilibrium. Increased CO₂ boosts photosynthesis, which removes CO₂. Mnemonic: ‘Negative = Neutralise the change – think thermostat.’
负反馈： 抵消变化，使系统回归平衡。CO₂升高促进光合作用，从而移除CO₂。记忆：’负=中和变化 一 就像恒温器。’
2. Water Cycle Terms | 水循环术语
Water cycle processes and hydrograph analysis are central to the Physical Systems component. Key terms often appear in data-response questions.
水循环过程与流量过程线分析是自然系统模块的核心。关键术语常出现在数据分析题中。
Evapotranspiration (ET): Combined water loss from evaporation (land/water surfaces) and transpiration (plants). Often the largest output in a water balance. Think ‘ET leaves the landscape’.
蒸散发： 地表蒸发与植物蒸腾作用的总水分损失。通常是水量平衡中最大的输出项。联想”ET外星人带走水分”。
Infiltration: Downward movement of water from surface into soil. High infiltration rates reduce surface runoff. Mnemonic: ‘In-FILTER-ation – soil acts as a filter.’
入渗： 水从地表向下进入土壤的运动。高入渗率降低地表径流。记忆：”入渗=渗入土壤过滤”。
Base flow: The sustained groundwater contribution to a river, maintaining flow between storms. It is crucial in recession limbs of hydrographs. Tip: ‘Base = baseline flow, always there.’
基流： 地下水持续补给河流的量，维持无雨期间的径流。它是流量过程线退水段的关键。提示：”基=基础流量，一直存在”。
Lag time: The delay between peak rainfall and peak discharge in a river. Urbanisation shortens lag time, increasing flood risk. Remember: ‘Lag = Late arrival of the flood peak.’
滞后时间： 降雨峰值与河道流量峰值之间的延迟。城市化缩短滞后时间，增加洪水风险。记住：”滞后=洪峰晚到”。
Water balance equation: A fundamental budget expressing the relationship between inputs, outputs and storage changes in a drainage basin.
水量平衡方程： 表达流域输入、输出与储存量变化关系的基本公式。

Carbon sequestration: The long-term storage of carbon in sinks such as forests, oceans, and geological formations. Quick memory: ‘Sequester = lock carbon away in a safe.’
碳封存： 碳在森林、海洋及地质构造等碳汇中长期储存。速记：”封存=把碳锁进保险箱”。
Carbon sink: A system that absorbs more carbon than it releases. Tropical rainforests and peatlands are major sinks. Mnemonic: ‘Sink swallows carbon – like a kitchen sink.’
碳汇： 吸收碳多于释放碳的系统。热带雨林和泥炭地是主要碳汇。记忆：”汇=汇集碳，如水槽汇集水流”。
Ocean acidification: Decline in seawater pH caused by absorption of excess CO₂, harming marine life. The chemical equation: CO₂ + H₂O → H₂CO₃ (carbonic acid). Remember ‘ACID-ification = lower pH.’
海洋酸化： 因吸收过量CO₂导致海水pH下降，危害海洋生物。化学式：CO₂ + H₂O → H₂CO₃（碳酸）。记住”酸化=pH降低”。
Weathering (carbonate): Chemical weathering of rocks (e.g., limestone) removes CO₂ from atmosphere. Rainwater + CO₂ forms weak carbonic acid that dissolves rock. Think ‘Weathering Weaken rocks and stores carbon.’
化学风化（碳酸盐）： 岩石（如石灰岩）化学风化消耗大气CO₂。雨水+CO₂形成弱碳酸溶解岩石。联想：”风化消碳，岩石变弱”。
Photosynthesis: Plants convert CO₂ and H₂O into glucose and O₂ using sunlight. It is the primary flux from atmosphere to biosphere. Equation reminder:
光合作用： 植物利用阳光将CO₂和H₂O转化为葡萄糖和O₂。是大气碳进入生物圈的主要通量。方程提示：
6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
4. Glacial Systems | 冰川系统
Glacial landscapes are dynamic systems driven by accumulation and ablation. Correctly using termini can gain marks in explain and assess questions.

积累： 冰川获得的冰和雪，主要通过降雪和雪崩。主要发生在积累区。记忆：”积=增加”。
Ablation: Loss of ice from a glacier via melting, sublimation, and calving. Remember ‘Ablation = Away-lation – ice goes away.’
消融： 冰川通过融化、升华和崩解损失冰量。记忆：”消=消失，冰不见了”。
Glacial budget: The balance between accumulation and ablation over a year. A positive budget leads to glacier advance.
冰川物质平衡： 一年内积累与消融的收支。正平衡导致冰川前进。
Glacial Budget = Accumulation – Ablation
Equilibrium line: The boundary separating the zone of accumulation (net gain) from the zone of ablation (net loss). Visual cue: a contour where budget is zero.
平衡线： 分隔积累区（净收益）与消融区（净损失）的界线。视觉提示：预算为零的等高线。
5. Coastal Landforms and Processes | 海岸地貌与过程
Coastal terminology blends processes and landforms. Often, processes create diagnostic features that can be identified from photographs or OS maps.

Eustatic change: Global sea level change due to water volume variation (e.g., ice sheet melt) or ocean basin shape. ‘Eu-static = truly global sea level.’
海面升降变化： 因水量变化（如冰盖融化）或洋盆形状引起的全球性海平面变化。联想’eustatic’是真正的静态变化。
Isostatic change: Local vertical land movement in response to loading/unloading of ice. Crust rebounds after ice retreat. Mnemonic: ‘ISO-static = same land rebounding after ISO-lation of ice.’
地壳均衡变化： 地壳对冰加载/卸载的局部垂直运动。冰川消退后地壳反弹。记忆：”均衡=地壳找平衡”。
6. Space, Place and Identity | 空间、地方与认同
These terms sit at the heart of Human Geography. They explore how individuals and groups perceive and shape their environments.
