the breakdown of rock into sediment

Explanation:

The sedimentary rocks are a product of the sediments of the igneous rocks. The igneous rocks are the ones that form first, but over the course of millions of years the weathering and erosion processes start to break them and move the fine material. As the sediments are moved, they eventually come into a situation where there's conditions which make the small sediments merge. In general it is heat and pressure that do this process, being finalized with the process of cementing. Once they are cemented naturally, the sediments form a unit, thus give birth to a certain type of sedimentary rock.
