Attrition describes the way rocks and pebbles knock into each other while being transported, becoming smoother and rounder.
磨圆作用 描述的是被搬运的岩石和卵石相互碰撞，变得更光滑、更圆润的过程。
Longshore drift is the zigzag movement of sediment along a coastline caused by waves hitting the shore at an angle.
沿岸漂移 是指波浪以一定角度冲击海岸，导致沉积物沿海岸线呈锯齿状移动的过程。
Memory hook: Picture the river as an angry chef – abrasion scrubs the pan, hydraulic action blasts with a high-pressure hose, and attrition is the stones being tossed together in a rock tumbler. For longshore drift, draw a zigzag arrow along a beach.
记忆挂钩：把河流想象成一位暴躁的厨师——磨蚀像是在刷洗煎锅，水力作用如同高压水枪喷射，磨圆作用则是把石头扔进滚筒里翻滚。对于沿岸漂移，可以沿着海滩画一个锯齿形箭头。
2. Weather and Climate | 天气与气候
Weather is the day-to-day condition of the atmosphere in a specific place, such as temperature, rainfall and wind speed.

城市化 是指一个国家居住在城镇地区的人口比例增加，常由乡城迁移驱动。
Settlement hierarchy ranks settlements by size and services, from isolated dwelling and hamlet to town and city.
聚落等级 按规模和服务功能对聚落进行排序，从孤立住宅、小村庄到城镇和城市。

10. Revision Memory Techniques | 复习记忆技巧
Mind maps help you connect related terms visually by placing a central topic in the middle and branching out with definitions, diagrams and examples.
思维导图 通过将中心主题放在中间，向外扩散出定义、图表和例子，帮助你在视觉上连接相关术语。
Flashcards with the term on one side and a simple image or mnemonic on the other are excellent for quick-fire testing.
一面写术语、另一面画简图或记口诀的抽认卡，非常适用于快速自测。
Mnemonics such as 'Shutters And Windows Let Sunshine In' for remembering coastal processes (Sliding, Abrasion, Wave pounding, etc.) turn lists into memorable sentences.
记忆术，例如用 “百叶窗和窗户让阳光进来” 的首字母记住海岸作用过程，可以把列表转化成好记的句子。
Keyword linking connects a term you are struggling with to a word you already know by sound or story; for example, 'meander' sounds like 'mean deer' – imagine a deer walking in lazy loops.
关键词链接 通过发音或故事，把你费劲的术语和一个已知词汇联系起来；例如，“meander（蜿蜒）” 听起来像 “mean deer（刻薄的鹿）”——想象一只鹿在懒洋洋地转圈。
Spaced repetition involves reviewing terms at increasing intervals, which moves them from short-term into long-term memory.
间隔复习 指以逐渐拉长的时间间隔回顾术语，从而把短期记忆转化为长期记忆。
Memory hook: Design your own A-Z geography dictionary. Every time you learn a tricky term, place it into a story that includes movement, colour or humour – the brain remembers narratives far better than isolated words.
记忆挂钩：自己编写一本 A-Z 地理小词典。每学到一个难记的术语，就把它放进一个有动作、色彩或幽默感的故事里——大脑对叙事的记忆远比对孤立单词要牢固得多。
