1. Tectonic Hazards | 板块构造灾害术语
Plate boundary (plate margin) – the edge where two tectonic plates meet. See it as the ‘fence’ between neighbours. There are constructive (plates move apart), destructive (plates move together), and conservative (plates slide past) boundaries.
板块边界（板块边缘）——两个板块相遇的边缘。把它想象成邻居间的‘篱笆’。分为建设型（板块分离）、破坏型（板块汇聚）和守恒型（板块平移）。
Subduction zone – a destructive margin where a dense oceanic plate sinks beneath a lighter continental plate. Think ‘sub’ = under; the ocean floor dives down, generating deep trenches and explosive volcanoes.
俯冲带——发生在破坏型边界，密度大的海洋板块沉入较轻的大陆板块之下。联想到‘sub’表示‘下’，洋底向下俯冲，形成深海沟与爆裂式火山。
Focus vs Epicentre – the focus is the underground point where an earthquake begins; the epicentre is the point on the surface directly above it. Link: ‘Epicentre’ sounds like ‘epidermis’ – the skin surface.
震源与震中——震源是地下地震起始点；震中是其正上方的地表点。联想：‘Epicentre’ 音似 ‘epidermis’（表皮），都在表面。
Richter scale – a logarithmic scale measuring earthquake magnitude. Each whole-number increase means 32 times more energy released. Memorise: ‘Richter’ rhymes with ‘sifter’ – it sifts out tiny shakes from giant ones.
里氏震级——测量地震震级的对数标度。数值每增加 1，释能约增 32 倍。记忆：‘Richter’ 与 ‘sifter’（筛子）谐音，能筛出微震与强震。

Hydraulic action – the sheer force of water hitting the bed and banks, trapping air in cracks. Link to ‘hydraulic’ car brakes: pressure does the work.
水力作用——水体冲击河床和河岸，把空气压入裂隙。联想到汽车‘液压’制动：压力做功。
Meander – a winding curve in a river’s middle/lower course. On the outside bend, faster flow erodes a river cliff; on the inside, slow water deposits a slip-off slope. Draw a twisting snake to visualise.
曲流——河流中下游蜿蜒弯曲的河段。凸岸流速慢、堆积形成浅滩；凹岸流速快、侵蚀形成河蚀崖。画一条扭动的蛇来想象。
Oxbow lake – a crescent-shaped lake formed when a meander is cut off. Imagine tying a loose loop of string and snipping it off – the isolated loop becomes the lake.
牛轭湖——曲流裁弯取直后留下的新月形湖泊。想象把绳子打一个松结然后剪掉，脱落的环就成了湖。
Levee – a raised embankment along a river channel, built up by repeated flood deposition. Think ‘levee’ sounds like ‘leave-ee’ – the river leaves sediment behind.

Longshore drift – the zigzag movement of sediment along a coast, driven by waves hitting at an oblique angle. Draw a saw-tooth pattern to remember the ‘drift’ along the shore.
沿岸漂移——波浪斜向袭岸引起的沉积物锯齿状沿岸运动。画一个锯齿状图案来记住这种沿海岸的‘漂移’。

7. Settlement | 聚落术语
Site and situation – site is the actual ground a settlement is built on (e.g. flat land, near a river); situation is its location relative to other places (e.g. on a trade route). ‘Site’ = physical spot; ‘situation’ = relation to surroundings.
地点与区位——地点指聚落实际所在的土地（如平坦土地、近河）；区位指其与其他地方的相对位置（如位于商路上）。‘地点’看脚下；‘区位’看周围。
