What is low islands?

Low islands are a type of island that are typically flat and have a low elevation. They are often formed from coral reefs and are found in tropical and subtropical regions. Low islands are also known as coral atolls, and are typically surrounded by shallow lagoons. Many low islands are home to unique and diverse ecosystems, including coral reefs, mangrove forests, and sea grass beds, which are important habitats for a variety of marine plants and animals. Due to their low elevation, low islands are also vulnerable to rising sea levels and storm surges caused by climate change.
