Chapter 5: Problem 10

Where is a lagoon in relation to a barrier reef? Where is it in relation to an atoll?

Short Answer

Expert verified

In relation to a barrier reef, a lagoon is located between the reef and the mainland, providing a protected area parallel to the coast. In relation to an atoll, a lagoon is situated at the center, enclosed by the circular or horseshoe-shaped coral reef, and may contain one or more islands within it.

Step by step solution

Understanding Barrier Reefs and Atolls

Barrier Reefs are long, continuous coral reef systems that run parallel to the coastline and are separated from the mainland by a deep lagoon. An Atoll is a circular or horseshoe-shaped coral reef, enclosing a central lagoon. It may sometimes have one or more islands inside the lagoon, and usually forms around a volcanic island that has subsided below the ocean surface.

Position of Lagoon in Relation to Barrier Reef

A lagoon is a shallow body of water, usually separated from a larger body of water by landforms such as barrier islands, reefs, or sandbars. In relation to a barrier reef, a lagoon is found between the reef and the mainland. The lagoon is protected from the open ocean by the barrier reef, which absorbs the energy of the waves and reduces erosion along the shoreline. The lagoon will be parallel to the coast and closer to the mainland.

Position of Lagoon in Relation to Atoll

In relation to an atoll, a lagoon is found in the central part, enclosed by the circular or horseshoe-shaped coral reef. The atoll's reef surrounds and protects the lagoon from the open ocean, creating a calm and sheltered environment for marine life. It is important to note that the lagoon is the central feature of an atoll and could contain one or more islands within it. In summary, a lagoon in relation to a barrier reef is found between the reef and the mainland, while in relation to an atoll, the lagoon is in the center, enclosed by the circular or horseshoe-shaped coral reef structure.
