在海洋和陆地的交界处,大浪和岩石交战,结果不断改变着地球上的海岸线。受到海浪和海流能量的推动,海水就一直移动着。在海浪一波波冲向海岸时,如果岩石上有裂缝或小洞,它们就首先受到侵蚀。举例来说,海湾就是海浪挖走软岩石后形成的景观。坚硬岩石山崖的底都也会受到海浪的侵蚀,下部的岩石一旦被挖空,上面的岩石就会崩塌。海浪会把侵蚀下来的岩块分类,小的随浪逐流,大的则在原地形成海滩。细沙和砾石也能在海岸边上造出指状的新生地。这幅跨页图显示出海洋一直在重塑英格兰多塞特地区的海岸线。
At the junction of the ocean and the land, big waves and the rock battle, the result is constantly changing the coastline on Earth. The sea water has been moving thanks to the waves and currents. When the waves hit the shore, they are first eroded if there are cracks or holes in the rocks. For example, the gulf is the landscape that forms when the waves excavated the soft rock. The bottom of hard rock cliffs are also eroded by the waves, and the rock below it will collapse once the lower rock is hollowed out. Waves will be eroded rock classification, a small wave by the crowd, the big is the formation of the beach in situ. Fine sand and gravel can also make finger-shaped new ground on the coast. The spreadsheet shows the ocean has been reshaping the coastline of Dorset England.
