Is chalk a sedimentary rock.

The Three Types of Rocks. Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.Sedimentary rocks are made of particles of sediments such as sand and clay, or the skeletons and shells of sea creatures. When layers of loose sediment are buried and pressed down under more layers, the particles slowly cement together and lithify (form rock). ... It is often found as bands within chalk.
