What is a notable characteristic of Europe's coastline?

Europe's coastline is notable for its large and varied structure, which reflects the continent's complex geological history and diverse environmental factors. The intricacies of Europe's coastline are evident through the presence of numerous fjords, bays, islands, and peninsulas, resulting from both tectonic processes and the effects of erosion by waves and tides over time.

This variety means that different regions exhibit unique coastal features, such as the rugged cliffs found along parts of the British Isles, the sandy beaches common in southern regions, and the intricate inlets characteristic of Scandinavian coastlines. The sheer diversity of coastal landscapes enhances not only ecological richness but also cultural and economic activities associated with maritime environments.

The other options do not accurately represent the complexity of Europe's coastline. For instance, asserting that it is predominantly straight and uniform overlooks the many natural formations that define it. Moreover, comparing its significance to Africa underestimates the intricate relationships between European nations and their coastlines in terms of trade, tourism, and biodiversity. Similarly, stating that the coastline is mainly rocky without sandy beaches fails to acknowledge the numerous beach areas that are vital for recreational activities and coastal ecosystems.
