While erosion is the process of removing sediment, submersion is when the sediment is submerged under water and eventually replaced back to its original location. This often takes place during violent storms, when sand is dragged or pushed underwater, and it tends to return back to the visible place (via wave action) it had previously been when the seas have calmed down. At its most extreme, submersion can temporarily submerse an island, and create islands as well.
When sea levels rise, submersion has a larger impact, and this can be very bad for island biodiversity. If or when an island that had previously not been affected by submersion is suddenly at risk, trees, plants, and animals are at risk. If the submersion of the island becomes regular, it will be more difficult for plants to grow and flourish, which begins a new cycle of coastal erosion and the negative impacts that come with it, including increased erosion and possibly permanent loss of the island, depending on how much of an island it is. The island below is very vulnerable to these threats, but an island like Hawaii would not be as such.
