In Lord of the Flies chapter1 who identifies the island as a part of the Coral Reef?

Answer 1

Nobody identifies the island as "being part of the Coral Reef." Do you perhaps mean the Great Barrier Reef which lies close to much of the Eastern coast of Australia? The location of the island is never given, it is just a typical tropical island partially protected by a coral reef. The island itself is composed of pink granite, so it was originally of volcanic origin. The island is described as being roughly boat shaped, with a mountain, falling down to the sea in cliffs at the blunt end. The mountain slopes gradually into jungle which gets flatter towards the pointed end, where it terminates in a rocky promontary, almost a small island, connected to the main island. There is a square shaped platform of pink rock that cut across the jungle and beach and juts into the lagoon like a jetty. A coral reef runs parallel to one side of the island, as if a giant had attempted to copy the shape of the island with a broken line traced in chalk. This reef protects the lagoon within from the open ocean. The other (wild) side of the island is unprotected by a lagoon.
