Islands formed by limestone animal skeletons?
Islands formed by limestone animal skeletons are called atolls. These structures are typically circular or oval shaped with a lagoon in the middle, and they are found in tropical regions with coral reefs. Atolls begin as volcanic islands and gradually sink as coral grows on the surrounding reefs, leaving a ring of limestone behind.
What are atolls?
Atolls are ring-shaped coral reefs, often found in the open ocean and surrounding a lagoon. They form from the growth of coral reefs around a submerged volcanic island that erodes over time, leaving a ring of coral islands. Atolls are typically found in tropical areas with warm, shallow waters.
What island is build from coral that forms on the flank of sinking volcano?
The island that is built from coral that forms on the flank of a sinking volcano is called an atoll. Atolls are usually ring-shaped islands formed from coral reefs that grow around the submerged crater of a volcano. Over time, as the volcano sinks, the coral continues to grow upwards, creating a circular or oval-shaped island.

What is a ring-shape coral island or string of islands surrounding a lagoon?
An atoll is a ring-shaped coral island or string of islands that surround a lagoon. Atolls typically form from volcanic islands that sink into the ocean, leaving a coral reef formation around the edge of the submerged island. The lagoon in the center of an atoll is often shallow and can support diverse marine life.
Example of atoll?

Are atolls high islands or low islands?
Atolls are low-lying coral islands that are formed from coral reefs growing around the rim of an ancient volcanic island that has sunk below sea level. They are characterized by a central lagoon surrounded by a ring of coral reef and sandbars.
