Why are the Maldives so flat?

I would have thought that, as islands, they would be the "peaks" of mountains/volcanoes sticking out of the water meaning they would be hardly flat at all.

The Maldives are coral islands. Coral starts to grow in reasonably shallow warm water and stops growing at sea level. Sea level changes and geological uplift can then move the coral tops slightly above sea level but it’s unlikely to get very high before it is eroded back.
