Islands can disappear due to erosion.

Erosion, caused by natural processes like wave action and weathering, can lead to the disappearance of islands over time. The constant wearing away of land can cause significant changes to the shape and size of islands, eventually causing them to vanish entirely. Rising sea levels due to climate change can exacerbate this process, posing a threat to low-lying islands around the world. Understanding the impact of erosion on islands is crucial for conservation efforts and the preservation of these unique ecosystems and habitats.
