Answer:
Coral
Step-by-step explanation:
A low island is an island that was formed from coral. There are two main ways in which a low island can be formed. First, it can be the result of sedimentation upon a coral reef. The second option is the uplifting of such islands. Low islands are usually made of poor, sandy soil, which means that it is usually not a good location for farming to develop, and they tend to be uninhabited, or inhabited by a very small number of people.
