In this lesson, the continuation of the topic of the sea focuses on the process of erosion and its impact on coastal features and landforms around the Maltese islands. A video in Maltese is shown that discusses the famous Azure Window’s collapse, its significance in the film industry, and the reasons behind its collapse, mainly due to natural erosion and long-term stress on the rock structure. Despite the unfortunate loss of the Azure Window, efforts are being made to preserve other coastal features by studying and monitoring them extensively.
