白色的悬崖。。。东苏塞克斯(The white cliffs of... East Sussex)

东苏塞克斯郡七姐妹悬崖的绝美景色不会永远存在。虽然英格兰东南部海岸线的其他地方已经修建了海防，但这片苏塞克斯遗产海岸线估计每年会滑出30到40厘米。这些陡峭的悬崖是由大块的粉笔脱落，留下垂直的表面而形成的。海洋起到了很大的作用，但雨水也渗入白垩层，在结冰时从内部将其开裂。不断剥落的岩石使悬崖表面闪闪发光，再加上未受破坏的海岸线，使七姐妹成为电影中的热门背景，从《赎罪》、《哈利波特》到《盗贼王子罗宾汉》。

This stunning view of the Seven Sisters cliffs in East Sussex won’t be around forever. While sea defences have been built elsewhere along south-east England’s coastline, this stretch of the Sussex Heritage Coast slips away by an estimated 30 to 40cm every year. Those sheer cliffs are created when large chunks of chalk fall away, leaving behind vertical faces. The sea plays a big part, but rainwater too seeps into the chalk layers, cracking them from within as it freezes. The constant peeling away keeps the cliff face sparkling white which, combined with the unspoilt coastline, makes the Seven Sisters a popular backdrop in films, from Atonement and Harry Potter to Robin Hood, Prince of Thieves.
