Chapter 5: Problem 9

Describe the kind of rock found in a typical organic reef.

Short Answer

Expert verified

The kind of rock typically found in an organic reef is limestone, primarily composed of calcium carbonate (CaCO3). This rock is formed from the accumulation of organic material, including coral exoskeletons, shells, and other calcareous organisms, and provides a solid, stable foundation for the growing reef ecosystem.

Step by step solution

Understand an organic reef

An organic reef is a structure formed by the accumulation of marine organisms, such as corals, algae, and other marine invertebrates. These organisms can create massive underwater structures that serve as habitats for numerous other species.

Identify the main components of a reef

The primary components of an organic reef are the living organisms that build the reef structure, such as corals and algae. Corals are marine animals that create hard, protective exoskeletons made of limestone (calcium carbonate). As more and more coral colonies grow and die, their exoskeletons accumulate and harden, forming the basis of the reef structure. Additionally, calcifying algae and other marine creatures can contribute to the development of the reef structure.

Describe the rock found in a typical organic reef

The kind of rock usually found in a typical organic reef is known as limestone, which is primarily composed of calcium carbonate (CaCO3). Limestone is formed from the accumulation of organic material, including the remains of coral exoskeletons, shells, and other calcareous organisms. Over time, as these remains build up and are compressed by the weight of the overlying material, limestone rock forms. This rock provides a solid, stable foundation for the growing reef ecosystem.
