How could changes in the sea level cause islands to disappear?

Answer 1

Changes in sea level could cause islands to disappear through various mechanisms such as:

1. Inundation: If the sea level rises, low-lying islands may become completely submerged underwater, causing them to disappear. This process is known as inundation.

2. Erosion: Rising sea levels can lead to increased erosion along the coastlines of islands. This erosion can gradually wear away the landmass of the island, eventually causing it to disappear entirely.

3. Saltwater intrusion: Higher sea levels can lead to saltwater intrusion into freshwater sources on islands. This can have detrimental effects on the vegetation and wildlife on the island, ultimately leading to its disappearance.

4. Storm surges: Higher sea levels can result in more frequent and severe storm surges, which can cause significant damage to the infrastructure and ecosystems of islands. Continued damage from storm surges can eventually lead to the disappearance of the island.

Overall, changes in sea level can have a range of impacts on islands, ultimately leading to their disappearance if the changes are significant and sustained.
