1. Map Skills and Grid References | 地图技能与网格参照
Grid reference: A set of numbers used to locate a specific point on a map, often given as a four-figure or six-figure reference. It uses eastings (across) and northings (up) to pinpoint places within a grid square.
网格参照：用于在地图上定位特定点的一组数字，通常提供四位或六位参照。它使用东距（横向）和北距（纵向）在网格方格内精确定位位置。
Contour line: A line on a map joining points of equal height above sea level. Closely spaced contours indicate a steep slope, while widely spaced ones show gentle terrain.
等高线：地图上连接海拔相等各点的线。密集的等高线表示陡坡，稀疏的等高线则表示平缓地形。
Scale: The relationship between a distance on the map and the actual distance on the ground. A scale of 1:50 000 means 1 cm on the map equals 50 000 cm (500 m) in reality.
比例尺：地图上的距离与地面实际距离之间的关系。比例尺 1:50 000 表示地图上 1 厘米等于实际 50 000 厘米（500 米）。
Compass rose: A symbol on a map that shows the directions: north, south, east and west, along with intermediate points like northeast. It helps orient the map correctly.
指南针玫瑰图：地图上的一个符号，标示北、南、东、西以及东北等中间方向。它有助于正确摆放地图。
Legend (key): An explanatory box on a map that explains the meaning of symbols, colours and patterns used. Always check the legend before interpreting any map.
图例：地图上的注释方框，解释所用符号、颜色和图案的含义。解读任何地图前务必先查阅图例。
Spot height: A point on a map with its exact altitude given in metres. It is often marked by a small dot and a number, unlike a contour line that shows continuous height.

2. Physical Landscapes: Rivers and Coasts | 自然地貌：河流与海岸
Erosion: The wearing away and removal of rock and soil by natural forces such as running water, waves, wind or ice. Rivers erode their banks and beds through actions like hydraulic action and abrasion.
侵蚀：流水、波浪、风或冰等自然力量对岩石和土壤的磨损和搬运。河流通过水力作用和磨蚀等作用侵蚀河岸和河床。
Deposition: The dropping of material that has been carried by water, wind or ice. A river deposits sediment when its speed decreases, forming features like floodplains and deltas.
沉积：由水、风或冰搬运的物质的堆积过程。河流在流速下降时沉积泥沙，形成泛滥平原和三角洲等地貌。
Meander: A winding bend in a river channel, usually found in the middle and lower courses. Erosion occurs on the outside of the bend, while deposition builds up the inside, forming a slip-off slope.
曲流：河床中的蜿蜒弯道，常见于中游和下游。弯道外侧发生侵蚀，内侧则因沉积形成浅滩。
Oxbow lake: A crescent-shaped lake formed when a meander is cut off from the main river channel. Over time, the narrow neck of the meander is breached during floods, leaving an isolated water body.
牛轭湖：曲流被截断后形成的月牙形湖泊。随着时间推移，曲流狭窄的颈部在洪水时被冲破，留下孤立的水体。
Longshore drift: The movement of sediment along a coastline caused by waves hitting the shore at an angle. It shifts sand and pebbles in a zigzag pattern, gradually building up beaches or spits.
沿岸漂移：由波浪斜向冲击海岸引起的沉积物沿海岸线运动。它以之字形移动沙子和卵石，逐渐堆积海滩或沙嘴。
Headland and bay: A headland is a resistant rock outcrop that sticks out into the sea, while a bay is a crescent-shaped indentation where softer rock has been eroded more quickly. These form along discordant coastlines.
岬角与海湾：岬角是突出海中的坚硬岩石露头，而海湾是软岩石被更快侵蚀后形成的月牙状凹陷。它们沿着不整合海岸线形成。
