掌握关键的地理术语就像拿到了一张世界地图的钥匙——一旦理解了这些语言，每一种地貌、过程和模式都开始变得有意义。这份指南将剑桥9年级地理最重要的词汇拆分成易于记忆的小块，利用词源、视觉想象和简单的对比，帮助你自信地记住每一个术语。
1. River Processes and Landforms | 河流过程与地貌
Abrasion (corrasion) – The wearing away of the river bed and banks by the load of sand, pebbles and boulders bouncing along the river. Think of sandpaper rubbing against a wooden surface; the particles act like an abrasive cleaner.
Abrasion (磨蚀/刻蚀) – 河床和河岸被携带的沙粒、卵石和巨石不断撞击而磨损。把它想象成砂纸摩擦木头表面；这些颗粒就像“磨料清洁剂”一样。
Attrition – Rocks and pebbles carried by the river knock against each other, becoming smaller, rounder and smoother over time. Picture stones in a rock tumbler – they lose their sharp edges.
Attrition (磨圆作用) – 河流搬运的岩石和卵石彼此碰撞，久而久之变得更小、更圆、更光滑。想象一下滚筒抛光机里的石头——它们失去了锋利的棱角。
Hydraulic action – The sheer force of water crashes into cracks in the river bed and banks, compressing trapped air and widening the cracks. Visualise a powerful jet of water breaking apart a wall.
Hydraulic action (水力作用) – 水流强大的冲击力冲进河床和河岸的裂缝，压缩被困的空气并使裂缝扩大。想象一股强大的水流冲垮墙壁。
Solution (corrosion) – Slightly acidic river water dissolves soluble minerals in rocks such as limestone and chalk, carrying them away invisibly. It is like a fizzy drink slowly dissolving a piece of chalk.
Solution / Corrosion (溶蚀) – 略带酸性的河水溶解岩石（如石灰岩和白垩）中的可溶性矿物，并无形地将它们带走。就像汽水慢慢溶解粉笔一样。
2. Coastal Erosion and Deposition | 海岸侵蚀与沉积
Longshore drift – The zigzag movement of sediment along a coastline caused by waves hitting the shore at an angle. Swash carries material up the beach at an angle; backwash pulls it straight back down. Remember “beach zigzag” and picture a leaf moving sideways along the shoreline.
Longshore drift (沿岸漂移) – 波浪以一定角度冲刷海岸时，沉积物沿海岸呈之字形移动。冲流将物质斜向推上海滩，回流则将其垂直带回。记住“沙滩之字形”，想象一片叶子沿着海岸线横向移动。
Abrasion (coastal) – Waves hurl sand and pebbles against cliffs, scraping and wearing them away. The cliff is sandpapered by the sea. Tip: same word as river abrasion – just the “tool” is waves instead of river flow.
Abrasion (coastal) 海蚀/磨蚀(海岸) – 海浪将沙子和卵石抛向悬崖，刮擦并磨损崖壁。悬崖被大海“砂纸打磨”。提示：和河流磨蚀是同一个词——只是“工具”变成了海浪。
Hydraulic action (coastal) – Waves force air and water into cracks in the cliff face, compressing air pockets that burst and weaken the rock. Think of a powerful wave exploding into a cave, shaking the rock.
Hydraulic action (coastal) 水力作用(海岸) – 海浪迫使空气和水进入悬崖表面的裂缝，压缩空气囊使岩石破裂和弱化。想象一股巨浪冲入洞穴，震动岩壁。
Attrition (coastal) – Rock fragments carried by the waves collide and gradually break down into smaller, more rounded pebbles. It works exactly like a sea-powered rock tumbler.
Attrition (coastal) 磨圆作用(海岸) – 海浪搬运的岩石碎片相互碰撞，逐渐破碎成更小、更圆的卵石。它就像一个用海浪驱动的滚筒抛光机。
Deposition – The dropping of transported sediment when a river, wave or wind loses energy. Remember “deposit” in a bank: you drop off your money. In geography, the energy drops and the material is left behind.
Deposition (沉积) – 当河流、波浪或风失去能量时，搬运的沉积物就会沉淀下来。记住银行存款“deposit”：你把钱存进去。在地理中，能量下降，物质就被“存放”在原地。
3. Types of Weathering | 风化类型
Weathering vs. erosion – Weathering is the breakdown of rock in situ (without moving), while erosion involves movement. An easy shortcut: Weathering breaks it down, erosion takes it away.
Weathering vs. erosion (风化与侵蚀) – 风化是岩石在原地的分解（不移动），而侵蚀则涉及搬运。一个简单的口诀：风化破坏它，侵蚀带走它。
Freeze-thaw weathering (frost shattering) – Water seeps into cracks, freezes and expands by about 9%, widening the cracks. Repeated freezing and thawing eventually shatters the rock. Imagine a water-filled bottle left in the freezer – it bursts.
Freeze-thaw weathering / frost shattering (冻融风化/冰冻破碎) – 水渗入裂缝，结冰时体积膨胀约9%，使裂缝扩大。反复冻融最终使岩石破碎。想象一瓶装满水的瓶子放进冰箱——它会爆裂。
Biological weathering – Plants, animals and microorganisms break down rocks. Tree roots grow into cracks and prise rocks apart; animals burrow. Think of a tree root lifting a pavement slab.
Biological weathering (生物风化) – 植物、动物和微生物使岩石破碎。树根长入裂缝并撬开岩石；动物打洞。想象树根顶起人行道石板。
Chemical weathering (carbonation) – Rainwater mixed with carbon dioxide forms a weak carbonic acid that dissolves rocks like limestone. Associated with cave, sinkhole and limestone pavement formation. Recall the word “carbon” in carbonation to link with carbon dioxide.
Chemical weathering / carbonation (化学风化/碳酸化) – 雨水与二氧化碳混合形成弱碳酸，溶解石灰岩等岩石。与洞穴、天坑和石灰岩路面等地貌有关。回想“carbonation”中的“carbon”（碳），与二氧化碳联系起来。
